Hi
variables defined in a for-loop are local to the forloop. Code outside the for loop can't access the local variables defined in a for-loop.

But the above program is giving compilation error. Can any one of u tell me the reason?

Hi!

But the loop can access the method variables, that's why the compiler finds two i variables IN the loop, the local one and the method one.

Hope it helps

I arranged the code given and hand no compiler error. Hope this helps.

class Test{

int i=5;


public static void main(String args[]) {

for(int i=1;i<=5;i++,System.out.println("welcome"));


}
}
