3. Infinite While Loop 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 termina...
The while loop loops through a block of code as long as a specified condition is true:SyntaxGet your own Java Server while (condition) { // code block to be executed } In the example below, the code in the loop will run, over and over again, as long as a variable (i) is less ...
class WhileLoopExample2 { public static void main(String args[]){ int i=10; while(i>1) { System.out.println(i); i++; } } } 在while后面的括号里面的循环条件是i>1,因为i的初始值是10(>1),在循环代码里面又不停地给i的值进行递增(i++)操作,i的值会越来越大,这样循环条件(i>1)永远返...
A while loop has a boolean test and a body containing statements, like this: int count = 0; while (count < 100) { // test: boolean test within (..) System.out.println("count:" + count); // body: statements within {..} count = count + 1; } System.out.println("all done!
In this tutorial, we will learn how to use while and do while loop in Java with the help of examples.
Outer Loop: 1 Inner Loop: 1 Inner Loop: 3 Outer Loop: 2 Outer Loop: 3 In the above example, we have used the nested while loop. Note that we have used the continue statement inside the inner loop. if(j == 2) { j++; continue: } Here, when the value of j is 2, the value...
inti=1;while(true){// Cannot exit the loop from hereif(i<=10){System.out.println(i);i++;}else{break;// Exit the loop}} OR, we know how to use them inswitchstatements. switch (switch-expression) { case label1: statements; break; case label2: statements; break; default: statement...

Loop unrolling: the Server VM features loop unrolling, a standard compiler optimization that enables faster loop execution. Loop unrolling increases the loop body size while simultaneously decreasing the number of iterations. Loop unrolling also increases the effectiveness of other optimizations. ...
