customcomparator.java

一些基本的java程序源代码

package tree.customcomparator;
import java.util.Comparator;
public class CustomComparator<T> implements Comparator<T> {
		public int compare(T o1,T o2){
			if(((T) o1).equals(o2))
				return 0;
			return ((Comparable<T>) o1).compareTo((T) o2)*-1;
			
		}
			
}
