Java String Interview Question
Q
If we have the following in a Java code:
String s="abc"; String s2="abc";
Then what will be output of:
System.out.println("s.equals(s2) = "+s.equals(s2));
System.out.println("s==s2 = "+(s==s2));

The correct answer is:
s.equals(s2) = true s==s2 = true
The following answer is wrong. Because both literals of the same string are interned as a single object by the Java compiler, as pointed out by Kevin.
s.equals(s2) = true s==s2 = false
