Java do-while loop is an Exit control loop.Therefore, unlike for or while loop, a do-while check for the condition after executing the statements or the loop body. For multiple statements, you need to place them in a block using {}.

First of all, let's discuss its syntax: while (condition(s)) {// Body of loop} 1. Java For Loop. With loops, we can simply write the print statement one time and run it for any number of times.It's just a simple example showing the importance of loop in computer programming. The statement is given in the do while loop, the statement execute for one time after that it only gets executed when the condition is true. In this tutorial, we learn to use it with examples. The condition evaluates to true or false and if it's a constant, for example, while (x) {…}, where x is a constant, then any non zero value of 'x' evaluates to true, and zero to false.Loop body is executed till value of variable a is greater than value of variable b and variable c isn't equal to zero.3.
