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...
Example 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 x x Java Essentials - While loop in java Share Watch on Java...
It is up to you the coder to insure that this loop eventually has a way to get out. Java willNOTfigure this out for you. So pay attention to your condition unless you want to be stuck in an infinite loop. An infinite loop example: You now have the tools at your disposal to make ...

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...
while loop Flowchart Syntax while(test condition){ //code to be executed } If the test condition inside the () becomes true, the body of the loop executes else loop terminates without execution. The process repeats until the test condition becomes false. Example: while loop in C // ...
In the above example the loop is terminated when x becomes 5. Here we use break statement to terminate the while loop without completing it, therefore program control goes to outside the while - else structure and execute the next print statement. ...
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...
