Help with compareTo()

[Santhan Rajah]

Hi!
Can anyone tell me what�s wrong here?
Pls, any help is appreciated.
Here is my code:
import java.util.*;

class Testa implements Comparable
{
public static void main (String argv [] )
{
String one="one";
String two="two";
int number=compareTo();

}
public static int compareTo()
{
int resultat=one.compareTo(two);
return resultat;
}
}
---------------------------------------------
Here is the compiler errors:
G:\Documents and Settings\Santhan\My Documents\Java\Testa.java:4: Testa should be declared abstract; it does not define compareTo(java.lang.Object) in Testa
class Testa implements Comparable
^
G:\Documents and Settings\Santhan\My Documents\Java\Testa.java:18: cannot resolve symbol
symbol : variable two
location: class Testa
int resultat=one.compareTo(two);
^
G:\Documents and Settings\Santhan\My Documents\Java\Testa.java:18: cannot resolve symbol
symbol : variable one
location: class Testa
int resultat=one.compareTo(two);
^

Will you please post the compiler errors that you get? This will help us teach you what they mean so that you will know when you get similar errors in the future.

Take a good look at the first compiler error? What's it saying?
It's saying that your class doesn't have a method called compareTo that takes an Object as the only argument.
The Testa class declaration says that it implements Comparable. The Comparable interface declares a method named compareTo that takes an Object as the only argument. So, the Testa class must implement such a method (or the class must be declared to be abstract).

import java.util.*;
class Testa implements Comparable
{
 public static void main (String argv [] )
 {
  String one="one";
  String two="two";
  //Here you should pass the String varible
  //one,two to the mothod
  int number=compareTo(one,two)
  //int number=compareTo();
  System.out.println(number);
 }
 //Here you should add the parameter to which 
 //call this method
 public static int compareTo(String one,String two)
 //public static int compareTo()
 {
  int resultat=one.compareTo(two);
  return resultat;
 }
}
 

You can copy and paste it to the compiler to run the programme and get the result
I hope that I can help you to finish programme
