Hi Sandeep Gupta, I think it is one.

sql tutorials and online test papers on

new String() creates a copy of "Hello Java" (which is an object itself), thus a second object.

If it was the same, then "Hello Java"==s would be true, but this isn't the case.

If we did String s = "Hello Java", and then did "Hello Java"==s, it would be true.

If we use the equals method, s.equals("Hello Java"), it will be true because that is comparing the contents of the strings.

Here's a quick example:

public static void main(String[] args) {
String a = "Hello Java";
String b = new String("Hello Java");
String c = b;
String d = a;

System.out.println("Hello Java"==a);
System.out.println("Hello Java"==b);
System.out.println("Hello Java"==c);
System.out.println("Hello Java"==d);

}

This prints out

true - a references the object "Hello Java"
false - b doesn't reference the object "Hello Java"
false - c doesn't reference the object "Hello Java"
true - d references the object "Hello Java"

When you use a literal in a java program, it creates an interned string object. So in the following:

String s = new String("Hello Java");

You've created an interned String object with "Hello Java" and a copy of that object in s.
