Comparing Object references after modification

Class Rectangle is defined as:

class Rectangle {
 public Rectangle(int l, int w) { 
    length = l;
    width = w;
 }
 public int length;
 public int width;
}

An object of type Rectangle is created and its reference r1 is assigned to another reference r2.

Rectangle r1 = new Rectangle(50,30);
Rectangle r2 = r1;

What will be the result of equality comparison r1 == r2 after modifying r2.length:

// modify r2.length
r2.length = 55;
// compare and print result   
System.out.println( r1 == r2 ? "Equal" : "Not Equal");
