the body. 

Syntax
initialization;
while(condition)

-----
body;
----
increment/decrement;

{

Inner-loop:(no of columns)

{

----

Ex

Scanner sc=new Scanner(System.in); //System.in defines standard input device i.e. Keyboard.

for getting the input from keyboard the statement should be in the format shown below

String ss=sc.next(); 

String ss=sc.nextline();     (From topic Getting input from Keyboard)
