Nested forloop in Java language

In this tutorial, we will discuss the concept of Nested forloop in Java language.

When a forloop exists inside the body of another forloop, it is known as nested forloop in java

Syntex

for (initialization; boolean_expresion; increment or decrement){
    // statement(s) inside the body

for (initialization; boolean_expresion; increment or dicrement){

      // statement(s) inside the body

}
}

Here we can see, a for loop is inside the body another for loop

Example programs     

Program 1 

This program displays square number pattern using nested whileloop

class forloop
{
public static void main(String args[])
              {

for(int x=1;x<=10; x++)   //Outer for loop
           {
System.out.println();
for(int y=1;y<=10; y++)
                           {
                                 System.out.print(y);
                            } 
                }
           }

}

When you execute the above code, it produces the following result
