Print Maximum And Minimum Values Of Integers From User Input

Apr 27, 2015

So I'm learning java from a website and I was tasked with creating a simple program which allows the user to enter a series of integers, then finally when they decide to input a non-integer the program will print the maximum and minimum values of the integers they entered. So for example if they entered 5, 4, 3 and 2 then enter a non-integer the program would output 5 (maximum value), then 2 on a new line (minimum value).

Here is my code:

import java.util.Scanner;
public class MaxMinPrinter {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int max = Integer.MIN_VALUE;
int min = Integer.MAX_VALUE;

[Code] ....

And this is what the output looks like:

Actual output
-------------------------------------------
Enter an integer: 5
- 10
-
- Enter an integer: -4
- 8
- -6
-
- Enter an integer: 11
- -1
-
- Enter an integer: q
- -1
- -6

When it's supposed to look like this:

Expected output
-------------------------------------------
Enter an integer: 5
Enter an integer: 10
Enter an integer: -4
Enter an integer: 8
Enter an integer: -6
Enter an integer: 11
Enter an integer: -1
Enter an integer: q
11
-6

Car Rental Program - Display User Who Spent Maximum And Minimum Rent

Apr 22, 2015

I am working on this rental program and got stuck in the last part. The program is about renting a car; after completing the rent process it displays the user who spent maximum and minimum rent. This is where I can't proceed. The program displays maximum values for both max and min. Here's the code I have written:

import java.util.Scanner; // program uses Scanner 
public class CarRentalTest {
public static void main( String[] args )
{
System.out.println("Welcome to Rental Portal");
Scanner input = new Scanner( System.in ); // create Scanner to obtain input from command window
CarRental details=new CarRental();

i need to calculate the minimum and the maximum, actually it seems to be easy but, the minimum should be the smallest number but 0..this is my code

Java Code:

Scanner s = new Scanner (System.in);
int max = 0 ;
int min = 0 ;
System.out.println(" Please enter 3-5 numbers");
int a = s.nextInt();
int b = s.nextInt();
int c = s.nextInt();

Write TreeMap That Can Hold Maximum Of 20 Colors And Minimum Of 8?

Dec 11, 2014

I am trying to write a TreeMap that can hold a max of 20 colors and a minimum of 8. I have a while loop using pollLastEntry to limit the max but I can't figure out how to set the minimum. The hex number is the map's key and the color name is the value. I tried to use entrySet() and iterator to just double the size of the map but map can't have multiple keys with the same value. It also seems that to set a minimum would require some kind of further input(which I'm trying to avoid) of colors and their hex numbers.

//Method to hard code the colors into the map
public TreeMap<String, String> cm() {
//Color Map <Hex number, Color name>
//Uses a TreeMap to keep all the colors organized by key
TreeMap<String, String> cMap = new TreeMap<String, String>();
cMap.put("FFFF00", " Yellow");

Pair Of Two Numbers - Return Average / Distance / Maximum And Minimum Value

Sep 27, 2013

I have been having difficulty with the weeks concepts in my online Java class, the program is to be as followed:

For this exercise you will implement a class called Pair, that represents a pair of two numbers.The Pair class should include the following constructor and methods:

CONSTRUCTORS
public Pair(double num1, double num2) -- Creates an object that represents a pair of double values

METHODS

public double getAverage() -- Returns the average value of the two numbers
public double getDistance() -- Returns the absolute vale of the distance between the two numbers
public double getMaximum() -- Returns the maximum value of the two numbers
public double getMinimum() -- Returns the minimum vale of the two numbers

Write a class called PairTest that tests your Pair implementation. The PairTest should prompt the user for the two values, create a Pair object with the values and then print the average, distance, maximum, and minimum of the pair. The input / output should look like the following:

Enter the first number: 5.5
Enter the second number: 3.0

Average: 4.25
Distance: 2.5
Maximum: 5.5
Minimum: 3.0

NOTE: For this exercise, your solution should not use any conditional statements. Instead you should use the methods provided by thejava.util.Math.

So far I have:

import java.lang.Math;
import java.util.Scanner;
public class Main
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
{
System.out.println("Please enter a value for the first number");

Identifying Difference Between Integers And Words From User Input

Feb 24, 2015

I am currently taking a computer science class in high school, and its my first time programming (2 weeks since i started). I have currently finished my program however there were a few details that bothered me. I was supposed to create a program which can calculate average of individual marks and then calculate all of the average marks previously entered by user. However I noticed something that bothered me, which was the fact that if i were to enter a number when asked to enter a name, it would assume that number is a name. Also when I asked for the 5 marks the program would run fine until an error occurs if i accidentally type in a letter or word. I have done some research and found system scanners however i still don't understand the concept in a looping situation. Here is what I have so far.

import java.io.*;
public class loopingEx6Final {
public static void main(String args[]) throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
double average, totalaverage = 0;
int Mark, Marktotal=0, marktotalsum=0, count=0;

Allow User To Input One Or More Integers And Store Them In Vector For Manipulation Later On In Program

Oct 1, 2014

I'm playing with vectors for the first time... What I'm trying to do is to allow a user to input one or more integers and store them in a vector for manipulation later on in the program... Here's the portion of the program I'm working with:

Java Code:

package com.itse2317;
import java.util.*;
public class VectorTest
{
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);

[code]...

My question is this: Is there any way to move from inputting integers to printing them, without entering a non-integer (for example, hitting enter)? I looked at the API for the Vector class, and either I'm not thinking about the problem the right way to be able to find an answer, or it's just not there.

Program That Find Minimum Value In Array Of Integers

Feb 3, 2014

I'm required to create a program that finds the minimum value in an Array of integers.

Here is my approach :

public class Person {
public static void main(String [ ] args){
int theArray[]=new int [10];
int result = 0;
for (int i:theArray){
if (i < Integer.MAX_VALUE)

[Code]...

I can't really progress from this position. I keep getting told to change the return type to int on main method, then when i do it says change it to void..

How To Change Value In Array Through User Input And Print Out Result

Dec 14, 2014

I have to do a small program about parking. In the 2-d array (parking lot), contains different kinds of cars, the user have to :

1)enter which car he wanna move,
2)what direction (w,a,s,d) and after that,
3) how many moves( not out of bound) he wants to make, and finally
4) we print out the new parking lot for his next move

And i am stuck at how to move the car to corresponding position and then prompt user for the next move?

For example:

I want to move A to the right by 1 (d)

擷取.PNG
print result:
擷取1.PNG

How do I do that? The code that i have right now

public class CarParkGame {
public static void main( String [] args) {
  String carPark[][] = new String [6][6] ;
carPark[0] = new String[] {"A","A","A","0","0","0"};
carPark[1] = new String[] {"b","0","0","0","0","c"};
carPark[2] = new String[] {"b","X","X","0","0","c","<exit>"};

How To Find Maximum Of Two Enum Values

Oct 6, 2014

I have a set of enum values (let's call then ONE, TWO, THREE.....). I want to find the larger of two of them. But max(ONE,THREE) gives a compile error as MAX isn't defined for type-safe enums. Fair enough.
 
I also agree that one shouldn't be able to use arithmetic functions on enums.
 
But as Enum implements Comparable, one can write a function which implements max and min, rather inefficiently I assume.
 
Is there a better way of getting the max/min of an enum? And if not, can the Java team be persuaded to implement it?

Input 10 Integer Numbers Into Array And Determine Maximum Value Entered

Apr 22, 2015

a. Write a Java program to input 10 integer numbers into an array named fmax and determine the maximum value entered. Your program should contain only one loop, and the maximum should be determined as array element values are being input. (Hint: Set the maximum equal to the first array element, which should be input before the loop used to input the remaining array values.)

b. Repeat 1a, keeping track of both the maximum element in the array and the index number for the maximum. After displaying the numbers, display these two messages:

The maximum value is: _________
This is element number __________ in the list of numbers

Have your program display the correct values in place of the underlines in the messages.

c. Repeat 1b, but have your program locate the minimum value of the data entered.

I did parts a and b but for part see i just want to know if i did it correctly or not

import java.util.Scanner;
public class MinimumValueArray {
public static void main(String[] args) {
//Variable Declaration
Scanner keyboard = new Scanner(System.in);
int size = 10;

[Code] ,.....

When I run it i get this The minimum value is 0.0

The element that holds the value is 0 right away. is this right for the minimum or am i supposed to enter values and it will display the minimum value like in parts a and b wit the maximum? will the minimum just always be 0 or ?

Writing A While Loop To Read Positive Integers From User Until User Enters EOF Character

Feb 24, 2014

import java.util.Scanner;
public class Project_5
{
public static void main (String[] args)
{
Scanner input= new Scanner (System.in);

[code]....

So I'm attempting to have this program take the users input of integers, pressing enter in between each one. If they enter a negative number it lets them know that its invalid. At the end of the program it takes all of the valid integers entered and must add them and average them. I've put the final println in there as a placeholder. If the user types in "6" then presses enter and types in "3" , the output is:

There were 3 valid numbers entered.
The sum of the valid numbers was --- and the average was ---.
There were 0 invalid numbers entered.

It then continues on allowing the user to enter more values. Here is the example output for correct code"

Enter a positive value (EOF to quit): 4
Enter a positive value (EOF to quit): 7
Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 2
Enter a positive value (EOF to quit): -1
The number "-1" is invalid.

Enter a positive value (EOF to quit): 8
Enter a positive value (EOF to quit): 0
Enter a positive value (EOF to quit): -4
The number "-4" is invalid.

Enter a positive value (EOF to quit): CTRL-D

There were 6 valid numbers entered.
The sum of the valid numbers was 29 and the average was 4.83.
There were 2 invalid numbers.

Unable To Print Repeating Integers In Array

Aug 5, 2012

I have a problem where i have to write some code to read through an int array and print out the different integers and how many times they occur. For example:

if the array contained the numbers 1,4,2,3,5,4,4,7,5,4,3,6,8,6,4,

i would need the print to appear something like this

integer: 1, times: 1
integer: 4, times: 5
integer: 2, times: 1

etc

as the array is read sequentialy from element 0 to the end. the program should find the integer value in the first element (increment a counter by 1) and then search all other elements to see if the integer reoccurs (counter++ for each time it reappears). obviously the counter would be the 'times' value in the second column.

My problem is i can get this accomplished yet i cant get the program to recognise when it has already registered an integer in a previous element and skip to the next element looking for a new integer. SO for each element in the array it prints the integer and then searches the entire array for the integer again and increments the counter accordingly. so in essence there is a line printed for each integer the number of times it actually occurs.

I simply wish to have my code to find an integer and the number of times it occurs. and then disregard the elements it has registered the previous integer in.

Also, keep in mind that i am NOT permitted to use any new data structures/arrays for storing/remembering values. I can only use int and double variables throughout.

what i have so far is this: with the array being customerID[] :

Java Code:

int num;
int counter;
for(int count = 0; count < customerID.length; count++)
{
counter = 0;
num = customerID[count];
for(int count2 = 0; count2 < customerID.length; count2++)

[Code]...

The output for the int array 1,1,3,0,3,2,0,4,1,3, looks something like this:

Integer: 1, Times: 3
Integer: 1, Times: 3
Integer: 3, Times: 3
Integer: 0, Times: 2
Integer: 3, Times: 3
Integer: 2, Times: 1

[Code]...

and as you can see lines are repeated for each time the same integer occurs in a new element. i just need my code to skip an element if the integer has been previously encounterd and recorded. i.e i need it to look more like this :

Integer: 1, Times: 3
Integer: 3, Times: 3
Integer: 0, Times: 2
Integer: 2, Times: 1
Integer: 4, Times: 1

with the first encountered integer being checked throughout the array and then moving to the next integer/element which is not the same as any previous.

Displaying Random Value Of Integers And Then Finding Missing Integer From Values In Array

I have a problem where I have to create random integers from 1 to n + 1. When the array is displayed I have to find the missing integer from the values that are displayed and show that value. I have to use O(n^2) and O(n) operations. I have created this code so far but I cannot figure out how to make my values display n + 1. It is only displaying values 1, 2, 3, 4 and 5 in random order. I also cannot figure out how to find the missing value. I have created a boolean displayed statement but can't determine how to use it in this code.

int[] numbers = new int[7]; //create array of numbers
Random random = new Random();
boolean displayed = false; //boolean value to determine if number was displayed
