JAVA编写程序，对英文单词按照字母顺序进行排序（升序or降序）

Question

降序排序后 Peter John Bill
改下面的，变成降序
import java.util.ArrayList;
import java.util.Collections;
public class Main {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
String target="John Bill Peter ";

ArrayList<String> list=new ArrayList<String>();
for(String temp:target.split(" "))
{
list.add(temp);
}

Collections.sort(list);

for(String temp:list)
{
System.out.print(temp+" ");
}

}

}

Answer 1

Easy!

import java.util.ArrayList;
import java.util.Collections;

public class Main {

/**
* @param args
* the command line arguments
*/
public static void main(String[] args) {
String target = "John Bill Peter ";

ArrayList<String> list = new ArrayList<String>();
for (String temp : target.split(" ")) {
list.add(temp);
}

Collections.sort(list);

for(int i = list.size(); i > 0; i--){
System.out.println(list.get(i-1) + " ");
}

}

}
