What will be the output of the program?
String x = new String("xyz");
String y = "abc";
x = x + y;
Answer: Option
Explanation:
Line 1 creates two, one referred to by x and the lost String "xyz". Line 2 creates one (for a total of three). Line 3 creates one more (for a total of four), the concatenated String referred to by x with a value of "xyzabc".

String x = "xyz";
String why = "abc";
String a = x + y;
String b = x + y;
System.out.println (a == b) ; // prints false.
Plus operator with variables will always create new object.
So in the above example it creates 4 objects.
String why = "abc";
String a = x + y;
String b = x + y;
System.out.println (a == b) ; // prints false.
