Which two statements are true about wrapper or String classes?

1.If x and y refer to instances of different wrapper classes, then the fragment x.equals(y) will cause a compiler failure.

2.If x and y refer to instances of different wrapper classes, then x == y can sometimes be true.

3.If x and y are String references and if x.equals(y) is true, then x == y is true.

4.If x, y, and z refer to instances of wrapper classes and x.equals(y) is true, and y.equals(z) is true, then z.equals(x) will always be true.

5.If x and y are String references and x == y is true, then y.equals(x) will be true.
