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 incre
If it is now “false”, the program exits the while-loop in Java and continues through the code. Example of a simple loop A simple example of a while-loop in Java is a counter that counts up to a certain value. It does this exactly until the specified value (the termination conditio...
Example A basic example of the Java while loop. Other supporting code was removed to improve readability and keep the code short. 1 2 3 4 5 6 intx =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 number...
Here is a simple java do-while loop example to print numbers from 5 to 10. package com.journaldev.javadowhileloop; public class JavaDoWhileLoop { public static void main(String[] args) { int i = 5; do { System.out.println(i); i++; } while (i <= 10); } } do while true ja...
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. ...
For example, if you want to show a message 100 times, then you can use a loop. It's just a simple example; you can achieve much more with loops. In the previous tutorial, you learned about Java for loop. Here, you are going to learn about while and do...while loops. Java while...
while loop is terminated. Flowchart of while Loop Example: Kotlin while Loop // Program to print line 5 times fun main(args: Array<String>) { var i = 1 while (i <= 5) { println("Line $i") ++i } } When you run the program, the output will be: Line 1 Line 2 Line 3 Line...
Example: For loop inC Compiler // Program to print numbers from 1 to 10#include<stdio.h>intmain(){inti;for(i =0; i <10; i++) {printf("%d\n", i+1); }return0; } Run Code >> The above code prints the numbers from 1 to 10 using aforloop in C. ...
The Java programming language also provides a do-while statement, which can be expressed as follows: do { statement(s) } while (expression); The difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the ...
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...
