Abreakstatement is used to exit the loop in awhile-loopstatement. It is helpful in terminating the loop if a certain condition evaluates during the execution of the loop body. inti=1;while(true)// Cannot exit the loop from here{if(i<=5){System.out.println(i);i++;}else{break;// E...
In computer programming, loops are used to repeat a block of code. 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, ...
