Can anybody give an example for this....

[Manoj Mani]

b.eqials(c) can return false even if c.equals(b) returns true.

Hi Manoj,

Don't you think, it violates the symmetric contract of the equals() method.

What is symmetric contract?
For any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.

Ya thats right?But......

Given that b and c refer to instances of wrapper classes, which two statements are true? (Choose two)
A. b.equals(b) returns true.
B. b.equals(c) returns the same result as b == c.
C. b.eqials(c) can return false even if c.equals(b) returns true.
D. b.equals(c) throws an exception if b and c are different wrapper types.
E. b.equals(c) returns false if the type of wrapper objects being compared are different.

Answer: B, C

Thats why i asked......
