When you enter the value 8, none of the cases will be
matched. Hence, the default case will be executed and
the output “Invalid day number” will be displayed on the

i + LOOPING STATEMENTS
Looping statements are the control flow statements that allow us to repeatedly execute a set of
statements for a given number of times. These are also called iteration statements or loops. Java
provides three kinds of looping statements, which are as follows:
• while • do-while • for
However, the for loop is more commonly used as compared to the while and do-while loops.
Let us learn about these in detail.
Start
The while Loop
The while loop is a flow control statement in Java. It is used
to execute a block of statements repeatedly until a given
condition becomes false. In a while loop, the condition is
Conditional False
evaluated first and if it returns true, then the statements
Expression
inside the loop are executed.
The syntax of the while loop is as follows:
True
while(< conditional expression >)
{ Body of while loop
[statements]
[increment/decrement expression]
}
For example:
public class WhileLoop
Stop
{
public static void main(String args[]) Flowchart of while loop
