java 中文字符串数组按照音序排列

浅沫记忆

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：

String[] str = {"北京","中国","亚运会"}; 
Arrays.sort(str,new SortComparator()); 
for(int len=0;len<str.length;len++){ 
System.out.println(str[len]); 
}
