Khalid's Question

[Arathi Rajashekar]

Hi,
Which expressions will evaluate to true if preceded by the following code
String a="Hello";
String b=new String(a);
String c=a;
char[] d={'H','e','l','l','o'};
Select all valid answers
(a=="Hello"); True
(a==b); False
(a==c); True
(a.equals(b); True
(a.equals(d); False
Are my answers correct?
My question is if we change "Hello" to "hello", the first line will result in false. Why is it so?
Can we define static method in abstract class?
I feel the answer is no

When using == with references, you're using the == operator to test if L.H.S. is the same reference as R.H.S. Hello and hello will be two different string literals, which is why the first line will result in false.
