![]() ![]() You can understand the while loop more clearly if you view the syntax and flowchart side by side. ![]() While the condition is true, the loop iterates. Any expression that meets the criterion is true, and a nonzero value does too. A single remark or a group of statements are both acceptable in this context. While loops are employed to execute statements up until a specified condition returns false continually. The loop will stop running if the condition is met. As long as the stated condition is true, it will repeat whatever many times it wants to. The iteration statements loop in Java is as follows:Īs long as the condition is true, a loop simply repeats a block of instructions. The same instructions are carried out by iteration statements up until a termination condition is satisfied. Iteration is the process of repeatedly running the same piece of code until a predetermined condition is met. Loops are produced by iteration statements in a program. When repeats are necessary during implementation, looping should be used instead of repeatedly writing the same statements. Why do we need looping?Ĭode repetition is the loop’s primary goal. Iteration statements are known as loops because of the way they repeat the execution of the statements in a circular pattern. In this instance, the loop’s execution ends when the condition becomes false. Looping is the process of continually executing a statement or set of statements up until the condition is met. Let’s first grasp what a loop is, why we need one, and the many sorts of loops that may be used in a Java program before learning how to use the while loop. Therefore, the terms "looping" and "iteration" have equivalent meanings. Iteration Statements are another name for looping statements. Please read our earlier articles, where we covered Java Language problems, The use of loop control statements is crucial for logical programming. So, quitting the while loop.While Loop in Java Language with Definitions, Syntax, Flow Charts, and Examples will be covered in this article. In the following example we are using the while loop to print integer value from 1 to 10.īut we will jump out of the while loop if the value is a multiple of 7. When the value of counter variable becomes 11 then the while loop condition fails and so, we come out of the loop.Įxample #2: Write a program in Java to print 1 to 10 using while loop but quit if multiple of 7 is encountered We are also incrementing the value of counter by 1 using the ++ increment operator. Inside the body of the loop we are printing "Hello World" using the println() method. This means we will execute the code inside the body of the while loop as long as counter is less than or equal to 10. So, we start with counter = 1 and the condition for the while loop is counter <= 10. We will execute the body of the while loop till counter <= 10. To solve this problem we will use a counter variable and initialise it with integer value 1. Or, we use the break statement to jump out of the loop.Įxample #1: Write a program in Java to print "Hello World" ten times using while loop To come out of the loop we make the condition false by updating its value in the body of the loop. Where, condition is some condition and if it is satisfied then we execute the body of the while loop otherwise, we ignore it. ![]() If we use the above approach then it's going to take a while to code and it will be an inefficient way of solving the problem. ![]() But now lets say the requirement changed and we are now required to display "Hello World" 1,000,000 times! To solve this we can print "Hello World" five times like the following. So, imagine we are given a task to write a program in Java to print "Hello World" 5 times. In this tutorial we will learn about while loop in Java programming language.Ī loop is a block of code getting executed over and over again as long as the given condition is satisfied. ![]()
