一个简单的颠倒数组的代码

public class ConvertArray{
public static void main(String[] args){
int[] a = {1,2,3,4,5};
int[] b = convert(a);

for(int i = 0;i < b.length;i++){
System.out.println(b[i]);
}
}

/**
* 反转数组
* @param src 源数组
* @return 转换后的数组
*/
public static int[] convert(int[] src){
if(src == null){
return null;
}

int length = src.length;
int temp = 0;
//反转
for(int i = 0;i < length / 2;i++){
temp = src[i];
src[i] = src[length - i - 1];
src[length - i - 1] = temp;
}

return src;
}
}
