Suppose there is an array of names and we want to print all the names in that array. The for loop is distinguished from other looping statements through an explicit loop counter or loop variable which allows the body of the loop to know. Lets take an example to demonstrate how enhanced for loop can be used to simplify the work. For loop is a programming language conditional iterative statement which is used to check for certain conditions and then repeatedly execute a block of code as long as those conditions are met. We recommend using this form of the for statement instead of the general form whenever possible.(as per JAVA doc.) 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.Īlso note that 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 read-only loop where you can’t update the values as opposite to other loops where values can be modified. 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. Loop termination:When the condition becomes false, the loop terminates marking the end of its life cycle.Increment/ Decrement: It is used for updating the variable for next iteration.Statement execution: Once the condition is evaluated to true, the statements in the loop body are executed.It is also an Entry Control Loop as the condition is checked prior to the execution of the loop statements. Testing Condition: It is used for testing the exit condition for a loop.An already declared variable can be used or a variable can be declared, local to loop only. Initialization condition: Here, we initialize the variable in use.Unlike a while loop, a for statement consumes the initialization, condition and increment/decrement in one line thereby providing a shorter, easy to debug structure of looping.įor (initialization condition testing condition for loop: for loop provides a concise way of writing the loop structure.ISRO CS Syllabus for Scientist/Engineer Exam.ISRO CS Original Papers and Official Keys.
