basicgenerator.java

看thinkinjava学习java时

package myutils;

public class BasicGenerator<T> implements Generator<T>{
	private Class<T> type;
	public BasicGenerator(Class<T> type){this.type = type;
	}
	public T next(){
		try{
		//Assumes type is a public class
		return type.newInstance();
	}catch(Exception e){
		throw new RuntimeException(e);
	}
	}

	//Produce a Default generator given a type token;
	 
	public static <T> Generator<T> create(Class<T> type) {
		return new BasicGenerator<T>(type);
		

	}
	
}
