String和Char[]相互转型

 1 public class StringChar {
 2     public static void main(String[] args){
 3         String s="abcdef";
 4         char[] x=s.toCharArray();     //String转为char[]数组
 5         String z=String.valueOf(x);   //char[]数据转为String
 6         System.out.println(x);
 7         
 8         for(char v:x)
 9         System.out.print(v+"*");
10         
11         
12         char[] data = {'1', '2', '3'};   //char[]数据转为String
13         String str = new String(data);
14         System.out.println(str);
15         
16     }
17 }
