For example, you could search through an int array looking for a specific value. The continue statement works similar to break statement. The while loop loops through a block of code as long as a specified condition is true: Syntax 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 than 5: Click the following links to check their detail. java for-loop infinite-loop. Here we'll use the boolean literal true to write the while loop condition: Now, let's use the for loop to create an infinite loop: An infinite loop can also be created using the less common do-while loop in Java.
