}
//public interface Comparator<T>
class Student implements Comparator<Student>{
private String name;
private int age;
public Student(String name,int sex)
{

import java.util.Arrays;
public class Test {
public static void sort(short[] a,
int fromIndex,
int toIndex){
}
public static void main(String[] args) {
Student[] a = new Student[] {
new Student("zhangsan", 20),
new Student("lisi", 22),
new Student("wangwu", 18)

Arrays.sort(a);//要求学生按年龄从小到大进行排序
System.out.println(Arrays.toString(a));
}
}
