关于选择排序的方法,该怎么处理

关于选择排序的方法
我的类程序：
package com.sodi.test;

public class Ssort {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int []intArray={12,11,45,6,8,43,40,57,3,20};
int keyValue;
int index;
int temp;
System.out.println("排序前的数组");
for (int i = 0; i < intArray.length; i++) 
System.out.println(intArray[i]+"");
System.out.println();
for (int i = 0; i < intArray.length; i++) {
index = i;
keyValue = intArray[i];
for (int j = i; j < intArray.length; j++) {
if (intArray[j]< keyValue) {
index = j;
keyValue=intArray[j];
}
temp =intArray[i];
intArray[i]=intArray[index];
intArray[index]=temp;
}
}
System.out.println("排序后的数组");
for (int i = 0; i < intArray.length; i++) 
System.out.println(intArray[i]+" ");

}

}

运行后：数组排序不对，请问有什么问题吗？
排序前的数组
12
11
45
6
8
43
40
57
3
20

排序后的数组
6  
11  
12  
45  
8  
43  
40  
57  
3  
20

[code=Java][/code]public static void main(String[] args) {

int keyValue;
int index;
int temp;
System.out.println("排序前的数组");
for (int i = 0; i < intArray.length; i++)
System.out.print(intArray[i] + " ");
System.out.println();
for (int i = 0; i < intArray.length; i++) { 
index = i;
keyValue = intArray[i];

intArray[index] = intArray[i];
intArray[i] = temp;
}
System.out.println("排序后的数组");

keyValue = intArray[i];
for (int j = i; j < intArray.length; j++) {

}
temp = intArray[index];
intArray[index] = intArray[i];
intArray[i] = temp;
}


这段循环中,循环j的大括号放错地方了~
[解决办法]

Java code

        int [] intArray={12,11,45,6,8,43,40,57,3,20};        Arrays.sort(intArray);        System.out.println(Arrays.toString(intArray));

真是无语啊，你在J循环里面干嘛要用到I，这样子你每次都是跟固定的值在比较了，这明显是错误的啊。
