Java do while loop / Chapter -4/ Flow Control

Java do while loop:-

If we want to execute loop body at least once then we should go for the do-while loop.

Syntax:-

do
{
         body
}  while (b);         

                         Where; the semicolon is mandatory and b always should be a boolean type.



1. The arguments should be a boolean type. If we are trying to provide any other type then we will get compile time error.

example:
int b=10;
do
{
         body

}  while (b); 

Compile Time Error: Incompatible Type
Found: int
Required: boolean
