JAVA怎么样把词语按顺序字母排列

词全存在
String dictionary[]里
怎么样按字母表顺序排列,如
about
advertisement
apple
bad
big
horse
....
是按字母顺序排列..

忘了说啊,不能用SORT()~~~

Answer 1

通过String的compareTo()方法比较大小
冒泡法排序
package com.zhh.test;

public class SreachC {

public static void sort(String[] list){
int len = list.length;
String temp = null;
for( int i = 0; i < len - 1; i++){
for( int j = 0; j < len - 1 - i; j++){
if((list[j].compareTo(list[j + 1])) > 0){
temp = list[j];
list[j] = list[j + 1];
list[j + 1] = temp;
}
}
}

}

public static void print(String[] list){

for (String str :list){
System.out.println(str);
}
}
public static void main(String[] args){

String[] list ={"apple","add","address","ban","ben","even","day"};
sort(list);
print(list);
}

}

Answer 2

String dictionary[]={"你的单词"};
Array.sort(dictionary);

for(int i=0;i<dictionary.length;i++){
System.out.println(dictionary[i]);
}
使用Array 的方法很方便的按字典顺排序
