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
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 condition) is reached. Written out, it looks like this: int i = 0; while ( i <= 5 ) { System.out...
while循环示例(简单版): class WhileLoopExample { public static void main(String args[]){ int i=10; while(i>1){ System.out.println(i); i–; } } } 输出: 10 9 8 7 6 5 4 3 2 while循环示例(死循环): class WhileLoopExample2 { public static void main(String args[]){ int i=10;...
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...
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...
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...
