Predict output:

public class PrefixPostfixCheck {

	public static void main(String[] args) {
		int i=5;
		i=i++;
		System.out.println(i);
	}
}

What will be the result of trying to compile and execute of the following program?

public class TestClass{

public static void main(String args[] ){

int i = 0 ;

int[] iA = {10, 20} ;

iA[i] = i = 40 ;

System.out.println(""+ iA[ 0 ] + " " + iA[ 1 ] + " "+i) ;

}

}
