Hi :-) I can do it with "J2SE1.3 + winnt40", do you use another kind of J2SE?
the following is testing code, as a reference.
BTW, if the constructor only "throw" "unchecked exceptions" such as Error or
RuntimeException, you don't need to:
- "throws" them in constructor
- "try-cacth" them when you make a instance of that class(so constructor is invoked)
public class override_nonnameClass{
public static void main (String args[]){
//try{
new AnotherClass(0){
public void myMethod(){
System.out.println("after overrided...");
}
}.myMethod();
//}catch(/*Throwable*/ /*Exception*/ ClassNotFoundException
te){te.printStackTrace();}
}
}
class AnotherClass{
private int i;
public AnotherClass(int i) /*throws*/ /*Throwable*/ /*Exception*/
/*ClassNotFoundException*/{
this.i=i;
if(i==0) {throw new /*Throwable()*/ Error() /*Exception()*/ /*RuntimeException()*/
/*ClassNotFoundException()*/ ;}
}
public void myMethod(){
System.out.println("before overrided...");
}
}
