Read Integer From Keyboard Until Negative Number Is Entered

Apr 8, 2014

Basically i have a question ask me to write a program that read integer from keyboard until a negative number is entered, and then print out the max and min out of the number i have entered.

This is what i have done already which works, but i need to ignore the negative number when print out max and min...which i dont know how to do so. when i compile this program now it will always give me the negative number i enter at the end as minimum. which i need to ignore

Also if negative number is entered at once the program should print a error message say max and min are undefined.

public static void main(String[] args) {

Scanner in = new Scanner(System.in);
int large = Integer.MIN_VALUE;
int small = Integer.MAX_VALUE;
while(true) {
System.out.print("Enter a integer: ");
int n = in.nextInt();

[Code] ....

Accept Array Of Non-negative Integers And Return Second Largest Integer

May 22, 2015

Write a function that accepts an array of non-negative integers and returns the second largest integer in the array.

Return -1 if there is no second largest.

The signature of the function is int f(int[ ] a)

Examples:

if the input array isreturn{1, 2, 3, 4}3{{4, 1, 2, 3}}3{1, 1, 2, 2}1{1, 1}-1{1}-1{}-1 

In the signature what I understood is, I should write my function with the given signature,

The return type is "int"

method name is "f"

parameter is "a" right ?
 
Writing my doubts beside the particular line in the code

public static void main()  // In the answer why they didn't use the class ?

In main method why they didn't use parameters ?(String[] args)

{
a1(new int[]{1, 2, 3, 4}); // what is "a1" here is it array name ? this line initializing the array ?
a1(new int[]{4, 1, 2, 3});
a1(new int[]{1, 1, 2, 2});
a1(new int[]{1, 1});
a1(new int[]{1});
a1(new int[]{});


static int a1(int[] a) // what is "a" here parameter ? and "a1" is method name ? why they used the array name and method name same ?

{
int max1 = -1;
int max2 = -1;
for (int i=0; i<a.length; i++)

[Code] .....

Change Negative Number To Positive Number?

Nov 20, 2014

I am 4 weeks into my Intro to Java course and I am having a bit of trouble with my code. I need to make a program that will take a user inputted number, space the numbers out, then add them to a total sum. What I am having a hard time with is when I enter a negative number. I can't figure out what I need to do to have my program ignore the "-" in the string.

import java.util.*;

Lotto Game - Receive Integer And Check If Int Was Not Entered Before

Nov 29, 2014

We were given the assignment to program a lotto game. in our game we should do follow the following steps below, and we are supposed to use atleast tree methods. the first one to receive the array of integers and an integer and check if the int was not entered before. the user should not repeat the same number. the other method will draw all numbers of a game (quantity of numbers to draw is based on the number parameter) and returns them in an array. the last method will display the result of the game. It receives a list of all lines played and a list of all numbers draw.

these are the steps to follow:

1. Ask the user how many lines (games) the user would like to play. Each line is made of five numbers between 1 and 45 (inclusive).

2. Ask the user to enter five numbers between 1 and 45 (inclusive) for each line. The user must NOT be allowed to enter a number more than once for each line.

3. When all the numbers for all the lines are entered, the program should display all lines and asks the user to confirm the game. If the user does NOT confirm the game, the program should start all over again.

4. Draw (generate) five numbers between 1 and 45 (inclusive). The numbers should be unique within the draw.

5. Draw (generate) one number (the bonus number) between 1 and 45 (inclusive). The number should be unique within the draw.

6. Display all the lines played and the result of each line.

7. Ask the user if the person would like to play again, if so the program should start the process all over again.

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 ?

Getting Negative Number For Product Of Odd Integers

Sep 18, 2014

I am not sure what is happening with my code, but it is giving me a negative number. I am trying to write a program that calculates the product of the odd integers between 1 and 25. I messed with the program and as soon as you enter a number over 22, the end result is a negative number.

int total = 1;
for (int i = 1; i <= 25; i += 2){
total *= i;
}
System.out.println("Product:" + total);

Removing Negative Number From Array

Jul 20, 2014

Ask the user to enter a sequence of at most 20 nonnegative integers. Your program should have a loop that reads the integers into an array and stops when a negative is entered (the negative number should not be stored). Invoke the average method to find the average of the integers in the array (send the array as the parameter).

how can I remove the negative number from the array and calculate the average of the posive elements without the negative ones? This is my code so far...

import java.util.Scanner;
import javax.swing.JApplet;
public class Parameters
{
//-------------------------------------
//Calls the average and minimum methods
//with different numbers of parameters

I could initializa to null, but that still is not the first number entered.

Averaging Grades Program - Take Input From User Until They Enter Negative Number

Feb 2, 2015

Ok so I have my program working for the most part. In this program I am supposed to take input from the user until they enter a negative number and that works, the problem is that it doesn't work if I enter a negative number on the first prompt. For example if I enter a 100 it would prompt me again and if I enter a negative number it would quit and give me the average, but if I enter a negative number the first time I am prompted the program just gives me an error. How do I fix that?

import java.util.List;
import java.util.ArrayList;
import java.util.Scanner;
public class Application {
public static void main(String [] args){
Scanner input = new Scanner(System.in);
List<Integer> grades;

Exception Thrown If User Enters Negative Number - Program Gets Suspended

Oct 19, 2014

In my cs class, we have to write a program that throws an exception if the user enters a negative number, the program should prompt the user to enter only positive numbers and then let them retype the number. But everytime I throw an exception, my program gets suspended.

What am I doing wrong, or is there no way to continue a program if an exception is thrown? Does the program automatically get suspended when an exception is thrown?

try{
do
{
N = kb.nextDouble();
if(N<0) {
throw new NegativeArraySizeException();
}
else
j++;
}
while(j==0);
fill.size(N);
}
catch(NegativeArraySizeException e) {
System.out.println("The number you entered must be positive. Please try again.");

Find If Number Entered By User Consecutive Or Not

Feb 21, 2014

I need to find if the number entered by the user are consecutive or not!

Ex:this should return a true!! This should return false!

(1,2,3) (3,5,7)
(3,2,4) (1,2,2)
(-10,-8,-9) (7,7,9)

My program seems to work ok when i enter number in order like 1,2,3 = true , and all the numbers for false seem to be working as well! my problem is when i enter number like 3,2,4 that are not in order but still are consecutive!! I thought that another if statement would be the solution but i have tray several different ones and still can't make it work !!!

Java Code:

import java.util.*;
public class Consecutive{
public static void main (String [] args){
Scanner console= new Scanner(System.in);
System.out.println("Enter three numbers");
String numbers = console.nextLine();

Allow Input To Loop Until 0 Is Entered For Product Number

What I am trying to do here is allow input to loop until 0 is entered for the product number. When 0 is entered, it should then dump the total for each individual product. I've tried it about a dozen different ways and have yet to be able to get the loop to function as intended. The way I have the code below, the loop will not function at all (where as before it looped, but never finished).

import java.util.Scanner;
public class Sales {
public static void main(String[] args) {
double total1=0.0;
double total2=0.0;
double total3=0.0;
double total4=0.0;
double total5=0.0;
int product;
