Quiz

So far, we have seen statements which have been executed one after the other in a sequential manner. Additionally, statements are provided in Groovy to alter the flow of control in a programs logic. They are then classified into flow of control statements which we will see in detail.

Loop Statement

A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages −

Groovy Loops

Groovy provides the following types of loops to handle the looping requirements:

1	While Statement The while statement is executed by first evaluating the condition expression (a Boolean value), and if the result is true, then the statements in the while loop are executed.
2	for Statement The for statement is used to iterate through a set of values.
3	for-in Statement The for-in statement is used to iterate through a set of values.
