Java (Do while loop)

DO WHILE LOOP IN JAVA

INTRODUCTION
In the Do while loop, statements (loop's body part instructions) executes first then, it will check the test condition and if the condition turns out to be true then the statements are executed again.


A do while loop runs at least once even though the test condition given is false.


int a=1;

do

{

System.out.println(a);

a=a+1;

}

while(a >10);

         OUTPUT 
----------------------------
1

Program Explanation: The above program will print only 1, because the do-while loop execute at-least once, even it test condition would be false.
