These statements are executed in the sequence. The loop body of the for loop can contain multiple statements. In such cases, a Java loop contains a null statement that is, an empty statement.Įxample of an empty loop: for( x = 0 x <= 10 x++) //See,the loop body contains a null statementĪn empty “for” loop finds its applications in the time delay loop where there is a need to increment or decrement the value of some variable without doing anything else, just for introducing some delay. We shall learn these methods with the help of example Java programs. In this tutorial, we will learn some of the ways to create an infinite for loop. To make the condition always true, there are many ways. When the loop-body of the for loop contains no statement, then it is called an empty loop. To make a Java For Loop run indefinitely, the condition in for statement has to be true whenever it is evaluated.
The following figure shows the working of Java “for” loop:Ĭode to illustrate the use of for statement/loop: package The “for” loop terminates if the test expression is false.
Java for loop update#
If the test expression evaluates to true, code inside the body of for loop executes and again the update expression executes.After the update expression, again, the test expression is evaluated.Statements inside the body of for loop start executing.If the test expression evaluates to true, The test expression is a boolean expression.ģ. After that, the test expression or test-condition executes. The initialization expression of the “for” loop executes only once.Ģ. The syntax of for loop is: for(initialization expression(s) test-expression update-expression(s))ġ.
All the elements of its loop-control that is, initialization, test-expression, and update-expression, gather at one place, that is, on the top of the loop within the round brackets(). The Java “for” loop is one of the easiest to understand Java loops. The number of iterations depends on the test-condition given inside the “for” loop. The “for” loop in Java is an entry-controlled loop that facilitates a user to execute a block of a statement(s) iteratively for a fixed number of times.
