Program Prints 2 Values When It Should Only Print 1

Feb 4, 2015

When I run this code, it is supposed to get one value from turnTimer(); and return it, just as a test. This works when I enter a valid pit. For example. If I were to input "A" when it's player one's turn, it will return 1, like it should. However, if I were to type "H" when it's player one's turn, it returns "Not a valid pit!"(like it should) but then it also returns 12. It shouldn't know that H is 12 because it's in a separate method. I'm confused as to why it's printing both values.

import java.util.*;
public class Mancala
{
static Scanner input = new Scanner(System.in);
public static int pit;
public static void main(String[]args)
{
Mancala mancala = new Mancala();
int[] board = {0,3,3,3,3,3,3,0,3,3,3,3,3,3};

Program That Prints Repeated Integer In Array

Apr 8, 2015

So I'm trying to write a program that prints out the "most-repeated integer" in an Array.

For example: if an array contains {1,2,2,3} It would print out 2 as the result.This is what I got so far and according to my knowledge I think I'm correct but for some reason it doesn't work.. Please give me some inputs.

public class MostInt{
public MostInt (){
int[] array = {0};
for(int i = 0;i>array.length;i++){
if(i==i++){
System.out.println(i);

Write A Program That Prompts User To Enter Two Positive Integers And Prints Their Sum

Jan 9, 2015

Write a program (TwoIntegers.java) that prompts the user to enter two positive integers and prints their sum (by addition), product (by multiplication), difference (by subtraction), quotient (by division), and remainder (by modulation). When the user enters 5 and 3, the output from your program should look exactly like the following:

Enter two positive integers: 5 3
The sum is 8.
The product is 15.
The difference is 2.
The quotient is 1.
The remainder is 2.

import java.util.Scanner;
public class TwoIntegers {
public static void main(String[] args) {
System.out.println("Enter two positive integers: ");
Scanner userInput = new Scanner("System.in");
int integer1 = userInput.nextInt();
int integer2 = userInput.nextInt();

JSP :: How To Print Null Values In EL

Dec 18, 2014

The value is: ${object1.property1} If the value of the property is null, I want "null" to be printed, like this:

The value is: null But I get an empty string, like: The value is:

I know I can use a ternary operator, but isn't there a simpler/shorter solution? A function (like NVL() in SQL)?

The value is: ${empty object1.property1 ? "null" : object1.property1 }

Not only is this long, but the value expression is typed twice, which is a magnet for bugs.

Print All Values In A Format Showing Their Key

Jun 14, 2014

Java Code:

public static void main(String[] args) {
HashMap<Integer, String> stuff = new HashMap<>();
stuff.put(1, "Book");
stuff.put(2, "Pancake");
stuff.put(3, "Waffle");

for(Map.Entry thing : stuff.entrySet())
System.out.println(thing.getKey() + ": " + thing.getValue());
} mh_sh_highlight_all('java');

So I make a HashMap which is pretty simple. My book showed me how I would print all the values in a format showing their key a ": " and the the actual value. What I don't understand is why the type element for the for each loop is the interface, Map.Entry.

Sort Values In Array And Print Median Value On Console

Oct 22, 2014

Use the sort method of the arrays class to sort the values in the array, and print the median value(the 50th value) on the console followed by a blank line. Then, test this enhancement. Print the 9th value of the array on the console and every 9th value after that. Then, test this enhancement.

import java.util.Arrays;
public class ArrayTestApp
{
public static void main(String[] args) {
double [] arrayTest = new double[99];
//adding random number to each element in the array
for(int i=0; i<arrayTest.length; i++)
arrayTest[i] = 100.0*Math.random();

[Code] ....

OUTPUT

run:

The average is: 49.842845462514944
The median is: 49.68753724038633
The 9th value is: 2.599530043466969
The 9th value is: 11.486193141397095
The 9th value is: 20.14206270200648

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

For Loop To Count Values Of Stack Of Quarters From 1.00 To 3.00 And Print Value Of Each Iteration

Nov 2, 2014

I had to write a foor loop to count the values of a stack of quarters from 1.00 to 3.00 and I had to print the values, that I understood and got it working so I taught the next assignment was going to be easier but I am having a hard time with it. For this one I have to write a for loop to print all the positive integer factors of 144 and I am supposed to print of factor per line but I tried doing that but it doesn't work it just prints out 144.

This is my code. The quarter assignment is also in there because it is part of a lab so just ignore that part since it is working correctly.

public class ForLoopPractice
{
public static void main(String [] args)
{
// Write a for loop to count out the values of a stack of quarters from $1.00 to $3.00
// Print the value of each iteration. Print this all on one line, rounded to the nearest cent.
// To print rounded, use printf, with a placeholder of %.2f
// (%f is the floating-point placeholder; the .2 indicates the number of decimal places)
/* YOUR CODE HERE */
for (double q = 1.00; q <= 3.00; q += .25)

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.

Program Should Print Array As Output

Jul 11, 2014

Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.

A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.

Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:

-insertNumbers, which will take as input one integer array and store the random numbers in it.
-createTremor, which will generate the random number as the location and return it.

A sample run of the program is shown below:

Sample output #1:
Array:1 2 2 3 1 5 4 2 3 4 4 2 1 1 3 2 1 4 3 2 1
Random position: 5
Final Array:1 2 0 0 0 5 0 0 0 4 4 2 1 1 3 2 1 4 3 2 1
