4) Assume that the following statements are executed in some method: int a = 42; Rectangle rect = new Rectangle (10, 20, 30, 40); // (x, y, width , height) We can then sketch a "memory map" showing the values of the local variables at this point. For a primitive type like int, the variable stores the actual value. For an object, the variable stores a reference to the object (which is somewhere else in memory) Rectangle rect y 20 width 30 height |40 a 42 (local variables) Then, trace execution of the remaining statements below. Sketch what the memory map looks like after all statements have executed, and show what the output is from the println ) statements Rectangle rect2 = new Rectangle (2, 4, 6, 8); int b = a; Rectangle rect3 = rect; rect3.setWidth (99); rect2. setX (137); b=b+5; System. out.println (a);' System. out.println (b); System. out.println (rect.getwidth ))
