![]() ![]() We wake up every morning and think of the tasks that we are going to accomplish in a day. To understand all these steps let us relate this to our day-to-day lives. It is also called Increment/Decrement expression since in most of the cases value of loop variables is either incremented or decremented. It is executed at the end of the loop when the loop-body has been executed and the next iteration is to start. It is used so that after some point of time the loop terminates. ![]() ![]() Update Expression(s): Here, we update the value of the loop variable(s).They are executed until the condition of the loop is true. Body of the Loop: The statements that are to be executed repeatedly are written in the body of the Loop.In an exit-controlled loop, the test expression is evaluated before exiting from the loop whereas in an entry-controlled loop the test expression is evaluated before entering the loop. If the condition is satisfied, the control goes inside the loop, otherwise, it is terminated. Its value decides whether the loop will be executed or terminated. Test Expression (Condition): It is a boolean expression.We can initialize multiple variables as well. Here, we either declare and initialize a control variable(s) or only initialize the variable(s) we are going to use in looping. Initialization Expression(s): Initialization is carried out only once before entering the loop.They also reduce the Time Complexity and Space Complexity - Loops are faster and more feasible as compared to Recursion.Loops make an easy flow of the control.Loops facilitates 'Write less, Do more' - We don't have to write the same code again and again.Eat -> Sleep -> Code -> Repeat Need for Looping Constructs in JavaĪ computer is most suitable for performing repetitive tasks and can tirelessly do tasks tens of thousands of times. for and while loops are entry-controlled loops whereas do-while loop is an exit-controlled loop.Ī very obvious example of loops can be the daily routine of programmers i.e. the for loop, the while loop, and the do-while loop. Looping Constructs in Java are statements that allow a set of instructions to be performed repeatedly as long as a specified condition remains true. ![]()
