Java interface to compare various data types

Question

I need to have an interface that will allow this to work for all data types if implemented with generics. Something to this effect.

  if (myIter.myDataType < SearchDataType){
      return myIter;
  }

or

  if (myIter.compareTo(SearchDataType)){
      return myIter;
  }

needs to work with integers, char, strings and even Boolean if possible. I'm new to java so I'm not aware of something that does this.

Answer 1

Something along the lines of:

class MyDataType<T extends Comparable<T>>{
    T data;

    public MyDataType(T _data){
        data = _data;
    }
}

Feels like a homework question. ;)
