In this section, you will create your first programming loop in Java using thewhilekeyword. You’ll use a singleintvariable to control the loop. Theintvariable will be calledxand will have an initial value of3.
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...
Java For Loop Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops un...

Or suppose you want to raise the price of everything in your store by 5 cents. Instead of doing these tasks manually, you would want to use a loop. In Java, for loops are used to run a specific task multiple times. Here’s the syntax for a for loop in Java: for (initialization;...
The difference between while and do-while in Java In addition to the while-loop in Java, there is also the do-while-loop. This not only has a similar name, but also works almost exactly like the while-loop. The main difference is that the head-controlled while-loop checks the terminat...
Can I use break in a while loop? Yes, the break statement can be used in any loop structure in Java, including while and do-while loops. What happens if I don’t use break in a loop? If you don’t use a break statement, the loop will continue to execute until its condition evalu...
