Redefining the method of interface

[New ID]

Hello,
In one of my program, I use a TreeMap to stock an object of type Foo. But I need time to recover given the smallest object Foo, then I have redefined the method compares of the Comparator interface. But all of this does not work for me. Please check my code

Public class mtrmp extends TreeMap implements Comparator {
 
   Public mtrmp() {
      great();
   }
 
   Public Intl compares(Object obj1, Object obj2) {
      test test1 = (test) obj1;
      Foo foo2 = (test) obj2;
		  
      / / Here I compare whether test1 <foo2 or test1> foo2 and foo2 = test1
      ....
   }
}

Please help me with this. Thanks in advance.

Hello,
I have a code with me , I think you should try it

import java.util .*;
 
Public class mytrmp extends TreeMap implements Comparator <somegen> {
 
   Public mytrmp()
   {
      great();
   }
 
   Public Intl compares(Stamped obj1, obj2 Stamp)
   {
      ...
   }
}

Hello,
The above is correct, I think you can alternatively try the following code.

Public class mytrmp extends TreeMap implements Compare {
 
   Public mytrmp() {
      great();
   }
 
   Public Intl compares(Object obj1, Object obj2) {
      System.out.System.out.println(obj1.getClass());
      System.out.System.out.println(obj2.getClass());

      Stamped test1 = (Stamped) obj1;
      Stamped foo2 = (Stamped) obj2;
       
      / / Here I compare whether test1 <foo2 or test1> foo2 and foo2 = test1
      ....
   }
}

Hello,
Yes, this is true, I too use the custom of ca and c is wrong. But AC is still not working. The above post solution I have not tried all of them but the one which I have tried does not work for me. But I will not be changing the concept of the program , i mean to see that the basic working of the program will remain the same , so, i have the challenge of doing a code with keeping the same program result.

Hello,
It does not always work? Is what you would have a use case that highlights a malfunction (by curiosity ) So to complete my previous post you can Implementer tone comparator in an inner class, As a comparator generally corresponds to a particular object type. If you need more information on this then you can visit the sun's official site for java and all the syntax and the methods and the classes are cleanly described there.

Hello,
I just bore you with the terminology: we implement the methods of an interface, re ca no sense. In short, we need your object implements the interface Similar to something like the regular one and not the comparator. You must therefore provide your object method compareTo (Object o) which returns an integer:

0 if your 2 items are similar
< 0 if the current object is of lower order
> 0 if the current object is of higher order

After all the sorting work.
