Java EE (Java Enterprise Edition) General Discussion

The subject really says it all. From what I can gather, the three have the same basic structure, but named differently depending on what context they are used? For instance, could the following class be any of the three:

public class Person {
  private String name;

  public void setName( String name ) {
      this.name = name;
  }

  public String getName ( ) {
      return ( this.name );
  }
}

Is my understanding correct?

Thanks,
Isaac
