[java] finding in a HashSet

[mickey]

Hello,
I'm new to java and my problem is this:

class Word {
    private String _value;
    public Word(String value) { _value = new String(value); }
}
 
 
//main
HashSet< Word >  dictionary = new HashSet< Word >();
dictionary.add( new Word( "goodbye" );
dictionary.add( new Word( "hi" );
dictionary.add( new Word( "hello" );
 
if ( dictionary.contains( Word( "hello" ) )) ) { //how to to this?
 
}

class Word {
    private String _value;
    public Word(String value) { _value = new String(value); }
}


//main
HashSet< Word >  dictionary = new HashSet< Word >();
dictionary.add( new Word( "goodbye" );
dictionary.add( new Word( "hi" );
dictionary.add( new Word( "hello" );

if ( dictionary.contains( Word( "hello" ) )) ) { //how to to this?

}

I need to know if dictionary contains that word. I know it's simple but I can't do it

Any hints, please?
