写的时候就出现这个情况
package collections;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class collections {
public void sort1()
{
List<String> mylist=new ArrayList<String>();
mylist.add("Kobe");
mylist.add("James");
mylist.add("Druant");
collections.sort(mylist);
}
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
