Arrays And Number Generator - Determine And Print Largest And Smallest Values
Dec 4, 2014
/*
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.

I just had this code working, then all of a sudden i was hit with a 'keyboard leak' error code.
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)
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;
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 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];
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;
Im trying to make a tic tac toe game that you play against the computer using a random number generator and two dimensional arrays for the game board. Im not trying to make a GUI, the assignment is to have the board in the console, which I have done. I have run into a few problems with trying to get the computer player to correctly generate 2 integers and have those two integers be a place on the game board. Here is my code so far.
import java.util.Random; import java.util.Scanner; public class TicTacToe { private static Scanner keyboard = new Scanner(System.in); private static char[][] board = new char[3][3]; public static int row, col;
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();
So im making this ghost game where i display an 8x8 filled with 0s and a randomly generator five 1s in there I can get it to display 0s and add 1s, however sometimes the 1s that are randomly generated sometimes go on the same spot making it look like there are only four 1s. How would i go about fixing that?
package Grade12; import java.util.Random; public class Ghost { public static void main(String[] args) { Random generator = new Random(); int gameboard [][] = new int [8][8]; int randomx, randomy, counter = 0, sum = 0; for(int row = 0; row < 8; row++){ for(int col = 0; col < 8; col++){ (gameboard[row][col]) = 0; }
I am working on a little nothing project, but I wanted to create a random number generator for a silly game where the user guesses the number.I have used google, but they are using LOG statements, what it does.
I have been stuck on this for the past 2 hours, basically we have to compare user input, put user input into an array and compare for equivalency. An example of the program:
Array 1 & 2 are equal Array 1 & 3 are not equal Array 1 & 4 are not equal.
This cannot be done by importing Java.util.Array at all!! (my research only find this to compare arrays ) which is why I am having trouble starting off. My code thus far:
import java.util.Scanner; public class Lab07b { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter Integer 1:"); int a = input.nextInt();
The international Olympics Committee has asked you to write a program to process the data and determine the medal winners for the pairs figure skating. You will be given the following file: Pairs.txt
Which contains the data for each pair of skaters. The data consists of each skater's name, their country and the score from each of eight judges on the technical aspects and on the performance aspects. A typical record would be as follows:
Smith Jones Australia 5.0 4.9 5.1 5.2 5.0 5.1 5.2 4.8 4.3 4.7 4.8 4.9 4.6 4.8 4.9 4.5
The final score for each skater is the sum of the average of the two categories of score. Design a class to hold the above data and the final score. Read the data in from the file and calculate the final score for each pair. Sort the array of objects , and display the results on the screen in order, giving special prominence to the medal winners.
Here is my CLass:
public class Skaters { private String name1; private String name2; private String country; private double [] arrTech = new double [8]; private double [] arrArt = new double [8]; private double score;
[code]...
how do i print my 2 arrays using the file? i got the name1, name2 and counntry to print but im stuck on printing the scores that are stored in the arrays. Also, i have to print the average for each array. one is for techniques and the other one is artistic. as you can see i already wrote the code for it but im stuck in printing it.
public static void main(String args[]) { Scanner in=new Scanner(System.in); System.out.println("Enter the Total Number of Integers:"); int totalInteger=in.nextByte(); long largest=0; for(int i=1;i<=totalInteger;i++) { System.out.println("Enter Integer-"+i+":");
[code]...
I want to get Index of that particular number in which Value is largest.
I need to create a program that uses ArrayList to store integers the user inputs, then scan the array for the largest number. I would also like the user to be able to exit this loop if the number 0 is entered.
As you can see below, I'm not sure how to correctly exit the do-while loop. I found this on another forum, but it does not work.
Java Code:
import java.util.*; public class array { public static void main(String [] args){ ArrayList<Integer> list = new ArrayList<Integer>();
import java.util.Scanner; public class AvgLrgSml{ public static void main(String[]args){ System.out.print("Hello there. Please enter any three numbers."); Scanner keyboard = new Scanner(System.in); double num1 = keyboard.nextDouble(); double num2 = keyboard.nextDouble();
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 brand new to programming and java. I decided I wanted to learn programming so now I'm in a class. I am into my second week and my assignment is to generate 100, 3 digit numbers then add them together. I understand how vast java is, but as of right now we have only studied if/else/switch statements, I was able to get the 100, 3 digit numbers generated, but I cannot add then together.
import java.util.Random; import java.util.Math; public class ThreeDigitGenerator { public static void main(String[] args) { int sum = 0;
public class printprimes2{ public static void main(String[] args){ for( int i = 1 ; i <=199 ; i++ ) //iterate 1 - 199; 2 is prime { for ( int j = 2 ; j < i ; j++ ) //iterate 2 - potential composite EXCLUSIVELY; every number can be divided by one and itself
[Code] ....
It doesn't print only prime numbers but all numbers that range from 0 to 199. What do you think I am doing wrong?
I am new at coding and I can't seem to figure out why my random number generator (numGen) won't let me compile. this is the game class to a game i'm making called Bagels. its very similar to the game mastermind in the sense that you have to try to guess a three digit number and the computer will return feedback giving you clues that will guess the number.
import java.util.*; import java.io.*; public class BaglesGame { public static numGen() { Random Rainbow = new Random (); firstDigit = "" + Rainbow.nexInt(10);
