The sample output is shown above as well as the running of the Java virtual machine.
JAVA FOR LOOP UPDATE
infinite loop because update statement It runs from 1 to 10 generating all the natural numbers in between. There are three phases in the loop statement.
JAVA FOR LOOP CODE
The sample code is given below as well as the output. In the first example, we are going to generate the first 10 numbers in a Java program using for loop. The syntax of a for loop in a Java program can be easily executed using the following.įor (initialization condition testing condition įollowing are the different examples: Example #1 Java is an entry-controlled loop as the condition is checked prior to the execution of the statement. Terminating the Loop– When the condition doesn’t satisfy in the testing condition phase, the loop closes and doesn’t work anymore.There can also be a decrement of 1 to the loop control variable if the condition of the program demands so. Incrementing/Decrementing Condition– In this phase, the loop control variable or the counter variable is incremented by 1 generally to move the code forward.Sometimes the print statement is also used within this phase. Statement Execution– In this phase, the print statement or the variable inside the for loop is executed making it easier to generate the output.Testing Condition– In the test condition, one of the counter variable variables is checked whether it is greater than or less than a certain quantity.Generally, the variables are initialized as zero or one. Initializing Condition– In the Initialization phase, we introduce the variables to be used in the Java program.

Let’s take an example to demonstrate how enhanced for loop can be used to simplify the work.
Note: The object/variable is immutable when enhanced for loop is used i.e it ensures that the values in the array can not be modified, so it can be said as a read-only loop where you can’t update the values as opposed to other loops where values can be modified. It is inflexible and should be used only when there is a need to iterate through the elements in a sequential manner without knowing the index of the currently processed element. Enhanced for loop provides a simpler way to iterate through the elements of a collection or array. Java also includes another version of for loop introduced in Java 5. The for loop has ended and the flow has gone outside.Įxample 1: This program will try to print “Hello World” 5 times.Updation takes place and the flow goes to Step 3 again.The statements inside the body of the loop get executed.If Condition yields false, the flow goes outside the loop.If Condition yields true, the flow goes into the Body.Update Expression: After executing the loop body, this expression increments/decrements the loop variable by some value. Otherwise, we will exit from the for loop.ģ. If the condition evaluates to true then, we will execute the body of the loop and go to update expression. Test Expression: In this expression, we have to test the condition. Initialization Expression: In this expression, we have to initialize the loop counter to some value.Ģ.
