public class StringCompare { 

 public static void main(String[] args) { int i; 

 String s1 = new String("Test"); String s2 = new String("Test"); String [] a = {s1, "test", "TEST", "TeSt"}; if (s1 == s2) System.out.println("Same"); for (i = 1; i < 3; i ++) 

 if (s2.equals(a[i-1])) s2 = s2 + " same as " + a[i-1]; 

 System.out.println(s2); } 

}

Can someone explain why this code prints what it prints? Please, explain how each line works. Thank you!
