Generic Classes

[marciojc]

hi folks,
i have a problem with a generic class.

abstract class Label<B extends Comparable<B>> implements Comparable<Label<B>>,Semiring<Label<B>>{

	private B value;
	
	/**
	 * Label constructor.
	 * Sets the value of Label <tt>value</tt>.
	 * 
	 *  @param value
	 */
	public Label(B value){
		this.value = value;
	}
	
	/**
	 * Returns the value of Label <tt>value</tt>.
	 * 
	 * @return <tt> B </tt> , the label value
	 */
	public B getValue(){
		return value;
	}

anda i have 5 instance of Label, for Integer, Double, ...
Because the operations define in Semiring are diferent for each type.

public class LabelInteger extends Label<Integer>{

	public LabelInteger(){
		super(0);
	}

	public LabelInteger(Integer value){
		super(value);
	}
...
}

Other class that i have is

when i make a new Label, i do

 Label<Integer> label1 want = new LabelInteger(1);

i want to do

 Label<Integer> label1 = new Label<Integer>(1);

any suggestion??
