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
