Hello,

I encountered a compile error in one of my classes when using the statement
"return super;" and compiling it with javac or jikes. JBuilder does not
complain. In my example doSomething() in class B contains this statement.

The error reported is:

Error in file ReturnType.java at line 31, column 37: '.' expected

I am wondering now whether the statement is valid or not? And of course why?

regards Ralph


public class ReturnType
{

 public class A
 {
  public String a = "A";

  public A doSomething()
  {
   return this;
  }
 }

 public class B extends A
 {
  public String b = "B";

  public A doSomething()
  {
   return super;                    <---- error
  }
 }


 public ReturnType()
 {
  B b = new B();

  A a = b.doSomething();
 }

 public static void main(String[] args)
 {
  ReturnType r = new ReturnType();
 }
}
