I am writing the code shown below:

```
String s1=new String("hi");
System.out.println(s1.hashCode());
String s2=new String("hi");
System.out.println(s2.hashCode());
String s3=s1.intern();
String s4=s2.intern();
System.out.println(s3.hashCode());
System.out.println(s4.hashCode());

```

When I run the code the same hashcode is printing for all variables:

```
3329
3329
3329
3329

```

Is it correct output for the above code?
