代码如下:
public class SortComparator implements Comparator{
public int compare(Object o1,Object o2) {
try{
byte[] buf1 = ((String) o1).getBytes("unicode");
byte[] buf2 = ((String) o2).getBytes("unicode");
int size = Math.min(buf1.length, buf2.length);
for (int i = 0; i < size; i++) {
if (buf1[i] < buf2[i])
return -1;
else if (buf1[i] > buf2[i])
return 1;
}
return buf1.length - buf2.length;
}catch(UnsupportedEncodingException ex) {
return 0;
}
}
}
调用：
代码如下:
String[] str = {"北京","中国","亚运会"};
Arrays.sort(str,new SortComparator());
for(int len=0;len
