Program To Display Both Largest And Smallest Of A Series Of 5 Integers
Apr 27, 2014
Here is a simple program on applets that is giving me a bit of headache since it cannot always display the two numbers that it is supposed to: the largest and smallest of the five input integers.....I cannot see where i went wrong, you can always create separately the HTML file to load the applet in an appletviewer of your won size.
*
23.6 (Largest and Smallest) Write an applet that reads five integers, determines which are the largest and smallest integers in the group and prints them. Draw the results on the applet.
*/
import java.awt.Graphics;
import javax.swing.JApplet;
import javax.swing.JOptionPane;
I have to get the user to enter in 10 numbers and with those 10 numbers I have to find the total, average, smallest, largest numbers in the set the user inputs. I have the total and average already figured out but how would you go about trying to find the largest and smallest numbers within this set of code.
import java.util.*; public class testhw7 { public static void main (String [] args) { Scannernumberin = new Scanner (System.in); doublevalue[]; doubletotal;
Write a program that finds both the largest and smallest of several integers. T. For example, a program that determines the winner and loser of a sales contest would input the number of units sold by each salesperson. The salesperson who sells the most units wins the contest; the salesperson who sells the least units loses the contest. Write a pseudocode program, then a Java program that inputs a series of 10 integers and determines and prints the largest integer and the smallest integer. Your program should use at least the following four variables: counter, number , largest and smallest. After i run the code i just get the largest input without the smallest .
This is my code :
import java.util.Scanner; // program uses scanner // main Class begins public class Largest12 { public static void main(String[] args) //main method begins { //Initial variables int counter = 0; // initiate counter int number=0 ;
I want to reverse grades that i have put using JOptionPane from largest to smallest and the corresponding names..
import javax.swing.*; import java.util.Arrays; public class ArrayUtils { public static void main (String[]args){ String length = JOptionPane.showInputDialog("Number of students");
I know it is possible to do this using the Array class but I don't want to use that. I am trying to use selection or bubble sort but I believe selection is what I want. This program asks the user to input 2 arrays with 10 integers each, sorts them from smallest to largest, then states whether they are the same or not. Comparing the two arrays.
import java.util.Scanner; public class SetDifference { public static void main (String args[]) { Scanner sc = new Scanner (System.in); int array1[] = new int[10]; int array2[] = new int[10];
I have to create a method with the following header :
public static <E extends Comparable<E> > void sort ( ArrayList<E> list , int left, int right)
i also had to create a swap cells method and position of max integer method. and also had to read the preserved data file in with a scanner. I implemented the comparable interface I am having difficulty sorting my list by the area. It has to be in descending order.
Geometric Object class: since it has comparator also am interested if i need to change this?
CODE:
Driver: public static void main(String[] args) throws IOException, ClassNotFoundException { Circle c1 = new Circle (4, "red", false); Circle c2 = new Circle (2, "blue", true); Circle c3 = new Circle (10, "blue", true); Rectangle r1 = new Rectangle (10, 6, "yellow", true); Rectangle r2 = new Rectangle ( 5, 11, "green", true); ArrayList <GeometricObject> list = new ArrayList();
Suppose s, t, and w are strings that have already been created inside main. Write a statement or statements, to be added to main, that will determine if the lengths of the three strings are in order by length, smallest to largest. That is, your code should determine if s is strictly shorter than t, and if t is strictly shorter than w. If these conditions hold your code should print (the boolean value) true. If not, your code should print false. (Strictly means: no ties)
/* Purpose: To write the methods and the rest program. The program should fill a 4 X 4 2 dimensional array with random numbers between 100 and 200. The program should then determine and print the largest and smallest values within the array using two Methods Largest and Smallest. The program should then determine and print the number of values within the array that are even using a function called Even. The program should also enter a loop that will only terminate when the user inputs a -1 as a choice. The loop should continue to ask the user to guess a number that was randomly generated. The program should call the Findit function to determine if the number was in the array. The program should print out the values in the array when the user selects a -1 and then terminate. */
import java.util.Scanner; import java.util.Random; public class LNFI_2DArray { public static void main(String[] args) { int guess; int[] array = new int[4];

I just had this code working, then all of a sudden i was hit with a 'keyboard leak' error code.
A java program to print 10 random numbers between 512 and 1024 and then finds the smallest and biggest numbers from the list using only one loop
class BSLab4d { public static void main (String[] args){ int[] nums = new int[10]; int largest = nums[0]; int x = 0; int smallest = nums[0]; int y = 0;
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++)
tfrreee i want to display given series in ascending order in java prog here is an error : E:Javajdkin>java ascend 505671Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 7 at ascend.main(ascend.java:9)
Java Code:
class ascend { public static void main (String args[]) { int s[]={ 50,71,81,21,7}; int i; for(i=0;i<=s.length;i++)
Description of the program: read a sequence of positive integers from terminal. When user types
-1, the program will print out the largest number and exit.
Program mid.java import java.util.Scanner; public class test { public static int num; public static void main (String[] args) { Scanner in = new Scanner(System.in); num = in.nextInt(); int large = num; while(num > 0); { if(0 > num && num > large) large = num; } System.out.println("The largest number is : " + large); } }
write a program to determine the sum of the following harmonic series for a given value of n:1+1/2+1/3+.............................+1/n the value of n should be given interactively through the keyboard.
import java.util.Scanner; public class smallestnumber { public static void main(String args[]) { Scanner input=new Scanner(System.in); int smallest =0; int number;
[Code]...
here is the output of my code:
Enter the number 88 Enter the number 8 Enter the number 6 Enter the number 55
I am trying to write a java program that prints out the number that is the mathematical constant e. As you input a number, the larger it gets , the closer it comes to 2.71828 . Here is my code:
//taylor series that prints out e^1=1+1/1!+1/2!+1/3!+..... import java.util.Scanner; public class taylor_1 { public static void main(String args[]) { Scanner input=new Scanner(System.in); int factorial =1;
I'm trying to change the code on a Fibonacci series program that would allow me to exit the loop early if I exceed a specified number. The user enters any 2 random numbers (which will be the 1st 2 no.'s of the Fibonacci sequence printed to screen) and then continues up to a 'limit' on the number of numbers set in code. Here's the code:
int[] array = new int[limit]; //Define an array whose length is set by an int value for limit!! array[0] = x; //User supplies a int value for x which takes the 1st position in the array!! array[1] = y; //...and an int value for y in the 2nd position!! for (int i = 2; i < limit; i++) //Start from the 3rd position of the array when carrying out calculations!! { array[i] = array[i-1] + array[i-2];
[Code] ....
To exit the code/ 'limit' early if the array prints a number higher than 100, I tried putting a 'while' condition before the last line, as follows:
while (array[i] < 100) System.out.print(array[i] + " ");
Can I even use a 'while' loop within an array, or is there some other way I need to integrate it?
For the latest assignment, my instructor has asked us to create a program where we create lines of at least for integers and if the program registers there being four of the same integer horizontally, vertically, or diagonally it returns true. For example:
If the program doesn't see four integers of the same value anywhere, it is supposed to return false. I've got it so it returns true for the lines above, 6x6 lines of integers and lines where only four out of six+ integers are equal. However, I cannot get my code to return false if there are only three matching integers in a row/column/diagonal nor can I get the program to print out either true or false for lines that do not start at the top left corner. (i.e 2 3 1 1 1 1) For the former I get this error message:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4 at ConnectFour.is4Consecutive(ConnectFour.java:41) at ConnectFour.main(ConnectFour.java:32)
For the latter:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 6 at ConnectFour.is4Consecutive(ConnectFour.java:43) at ConnectFour.main(ConnectFour.java:34)
The answer to fixing my code is probably something small or something that will make me wonder why I hadn't thought of it myself... Here is my code:
import java.util.Scanner; public class ConnectFour { private static Scanner sc; public static void main(String[] args) { sc = new Scanner(System.in); System.out.print("Enter the height: "); int h = sc.nextInt(); System.out.print("Enter the width: ");
So I need to generate 10 random integers in the range 1-20 but i have to store them in an array called numbers. Then I have to call a method called displayArray which displays the contents of the array and for the assignment i have to use a for loop to traverse the array. The method header for the displayArray method is:
public static void displayArray(int[] array)
This is what I have done
public class RandomIntegers { static int numbers = 0; public static void displayArray(int[] array) { System.out.println(numbers + "Numbers Generated");
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..
Project is due before midnight eastern time (3 more hours). I have been working on this all day, we have not learned arrays or anything and just started 'for' loops. I don't really know how to implement that system yet. However, he wants us to check all the possible handwritten math ways of doing this. I have tried but I cannot return my numbers beside the card.my program only prints the type and I still have more cases to add as well..
QUESTION: Write a Java program that reads 5 integers, each of which is in the range of 1 and 13 representing a simplified poker card with no suit. Your program should then print the ranking of the hand with card number(s) beside the ranking. The rankings to determine are Four of a Kind(4 of the 5 cards of the same rank), Full House(3 of the 5 cards of the same rank, and 2 cards of another rank), Straight(5 cards of sequential rank), Three of a Kind(only 3 cards of the same rank), Two Pair(2 cards of the same rank, 2 cards of another rank, and no card of either rank), One Pair(only 2 of 5 cards are of the same rank), and High Card(no two cards of the same rank). Some sample runs are:
input: 2, 3, 2, 2, 2; output: Four of a Kind(2) input: 2, 3, 2, 3, 2; output: Full House(2, 3) input: 2, 3, 4, 5, 1; output: Straight(5) input: 1, 13, 11, 10, 12; output: Straight(1)
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.
