java中ASCLL與字符串的互轉

其實在java中，ascii碼與字符串的互轉，通過對int型和char型的強制轉換就可以了

public class Change{

  //字符串轉換為ascii
  public static String StringToA(String content){
    String result = "";
    int max = content.length();
    for (int i=0; i<max; i++){
      char c = content.charAt(i);
      int b = (int)c;
      result = result + b;
    }
    return result;
  }

  //ascii轉換為string
  public static String AToString(int i){
    return Character.toString((char)i);
  }
  public static void main(String args[]){
    //請在終端運行
    System.out.println(StringToA(args[0]));
    System.out.println(AToString(new Integer(args[1])));
  }
