MySort的实现

代码：
package week12;
import java.util.*;
import java.lang.Integer;
public class MySort{
public static void main(String [] args){
String [] toSort = {"aaa:10:1:1",
"ccc:30:3:4",
"bbb:50:4:5",
"ddd:20:5:3",
"eee:40:2:20"};
System.out.println("Before sort:");
for (String str: toSort)
System.out.println(str);
int [] a = new int[toSort.length];
for (int i = 0; i < toSort.length; i++){
String [] tmp = toSort[i].split(":");
a[i] = Integer.parseInt(tmp[1]);
}
Arrays.sort(a);
System.out.println("After sort:");
for (int i = 0; i < a.length; i++)
for (int j = 0; j < toSort.length; j++)
if (a[i] == Integer.parseInt((toSort[j].split(":"))[1]))
System.out.println(toSort[j]);
}
}
