Programmers makes mistake. If theconditional-expressiongiven in while loop never terminatesthen the loop will result in an infinitewhile-loop. For example, in the previous program, if theindexvalue is not incremented after each iteration, then the condition will never terminate. In the next example...
If the body of loop has only one statement, it's not necessary to use curly braces{ }. Example: Compute sum of Natural Numbers // Program to compute the sum of natural numbers from 1 to 100.funmain(args:Array<String>){varsum =0vari =100while(i !=0) { sum += i// sum = sum...
A basic example of the Java while loop. Other supporting code was removed to improve readability and keep the code short. int x = 0; while (x < 5) { System.out.println(x); x = x + 1; } 0 1 2 3 4 As shown above, the while loop printed out all the numbers from 0 to 4....
truein the do while loop. Here is a simple do while java infinite loop example. package com.journaldev.javadowhileloop; public class DoWhileTrueJava { public static void main(String[] args) throws InterruptedException { do { System.out.println("Start Processing inside do while loop"); // l...

Java For and While LoopsThis handout introduces the basic structure and use of Java for and while loops with example code an exercises. See also the associated CodingBat java loop practice problems using strings and arrays. Written by Nick Parlante. ...
Example 1: while Loop using System; namespace Loop { class WhileLoop { public static void Main(string[] args) { int i=1; while (i<=5) { Console.WriteLine("C# For Loop: Iteration {0}", i); i++; } } } } When we run the program, the output will be: C# For Loop: Iterati...
In this program, the statement under Do would run at least once before the condition is evaluated. Even if you were to change ‘while(count < 1)’, the output would show at least “Count is: 1” Let’s see how Do While loop works with an example. ...
int loop = 1; while(loop<=5){ Integer.parseInt(JOptionPane.showInputDialog("Enter a number: ")); if(num<0) negative++; if(num>=0) positive++; loop++; } JOptionPane.showMessageDialog(null,"Negative numbers in the program: " + negative + "\nPositive numbers in the program: " + pos...
To properly explain the NullPointerException, we will consider the following Java program: class NullPointerExample { public static void main(String[] args) { String name = "James Gates"; System.out.println(name.length()); // Prints 11 name = null; // assigning a value of null to name...
