Java sorting of Array objects

The following is a set of code to sort the array objects:

 PackageCom.sun;Importjava.util.ArrayList;Importjava.util.Arrays;Importjava.util.Collections;ImportJava.util.Comparator;Importjava.util.List; Public classTest09 {/**     * @paramargs*/     Public Static voidMain (string[] args) {//TODO auto-generated Method StubDog dog[]=NewDog[3]; dog[0]=NewDog ("Wangchai", 10); dog[1]=NewDog ("Laifu", 9); dog[2]=NewDog ("ww", 20);        Arrays.sort (dog);  for(inti=0;i<dog.length;i++) {System.out.println (dog[i].name); }    }}classDogImplementscomparable{ PublicInteger Tizhong = 0;  PublicString name = "";  PublicDog (String name,intTizhong) {         This. Name =name;  This. Tizhong =Tizhong; }    //Sort by age@Override/*public int CompareTo (Object o) {//TODO auto-generated method Stub Dog s= (dog) o;    Return tizhong>s.tizhong?1: (tizhong==s.tizhong?0:-1); }*/    //Sort by name/*public int CompareTo (Object o) {dog s= (dog) o;             int Result=name.compareto (s.name);       return result; }*/    //If you first sort by number and then by character, write this:      Public intcompareTo (Object o) {Dog s=(Dog) o; intresult= tizhong>s.tizhong?1: (tizhong==s.tizhong?0:-1); if(0==result) {Result=Name.compareto (s.name); }             returnresult; }}
