1: Byte b1 = new Byte("127");
2:
3: if(b1.toString() == b1.toString())
4: System.out.println("True");
5: else
6: System.out.println("False");
The above code will print False? Why? In line 3, if replace "==" by equals() method, will output change? Thanks.
Luk

Hi Luk
By the "toString" method, two objects are created which are different , so the answer is FALSE.
If you replace '==' by 'equals' then answer is true, because String class overrides the equals methods and compare the contents of String objects.
Hope this clarifies.
