//主要用到: Collections.sort方法:
package com.tom.compare;import java.util.ArrayList;import java.util.Collections;import java.util.ComparaTor;import java.util.List;public class CompareClient {/** * @param args */public static void main(String[] args) { // TODO Auto-generated method stub List list = new ArrayList(); list.add(new Content(15000,"1asdfasd5000")); list.add(new Content(10000,"10000")); list.add(new Content(20000,"20000")); list.add(new Content(30000,"30000")); list.add(new Content(25000,"25000")); list.add(new Content(13000,"13000")); list.add(new Content(15000,"15000")); list.add(new Content(89000,"89000")); ContentComparaTor comp = new ContentComparaTor(); Collections.sort(list,comp); Content content; for(int i = 0; i " content.getName() " + content.getName()); }}}package com.tom.compare;import java.util.ComparaTor;public class ContentComparaTor implements ComparaTor {public int compare(Object o1, Object o2) { // TODO Auto-generated method stub Content c1 = (Content) o1; Content c2 = (Content) o2; if (c1.getKey() > c2.getKey()) { return 1; } else { if (c1.getKey() == c2.getKey()) { return 0; } else { return -1; } }}}package com.tom.compare;public class Content {private long key;private String name;public Content(long key, String name) { this.key = key; this.name = name;}public long getKey() { return key;}public void setKey(long key) { this.key = key;}public String getName() { return name;}public void setName(String name) { this.name = name;}}
结果是:
content.getName() 10000content.getName() 13000content.getName() 1asdfasd5000content.getName() 15000content.getName() 20000content.getName() 25000content.getName() 30000content.getName() 89000
