yes java support call by reference only using StringBuffer
class.

Here, is an example of call by reference

public class PassByReference
{
public static void passref(StringBuffer s)
{
s = s.insert(8, "j2ee & ");
System.out.println(s);
}
public static void main(String[] args)
{
StringBuffer str = new StringBuffer("Welcome java
program");

System.out.println(str);

passref(str);

System.out.println(str);
}
}


output :-

Welcome java program
Welcome j2ee & java program
Welcome j2ee & java program

how come we know the object is no more used in the class?
