java how to "I love you my 123 abc " into "I love you [Aa] [Bb] [Cc] I 123"

java how to "I love you my 123 abc " into "I love you [Aa] [Bb] [Cc] I 123"
------ Solution ---------- ----------------------------------
If we say , simply convert the string you give it, It can be processed .
assume that all strings to "String - letters - characters - numbers" such treatment , then, need to be adjusted.
I novice , as follows , and all the great God laughed . ( Also see instructions )

  public class ConvertTest {
  	/**
  	 * java中如何将"我爱你abc我123"转换成"我爱你[Aa][Bb][Cc]我123"
  	 * @author Milo 2013-9-10
  	 * @param args
  	 */
  	public static void main(String[] args) {
  		String s = "我爱你abc我123" ;
  		System.out.println("Start with : " + s);
  		String result = myString(s) ;
  		System.out.println("End with : " + result);
  	}
  	public static String myString(String s){
  		String[] st = new String[]{"我" , "爱" , "你"} ;
  		StringBuffer sb = new StringBuffer() ;
  		char[] ch = s.toCharArray() ;
  		for(char cha : ch){
  			for(String str : st){
  				if(String.valueOf(cha).equals(str)){
  					sb.append(str) ;
  				}
  			}
  			if(cha >=48 && cha <=57 ){
  				sb.append(Integer.parseInt(String.valueOf(cha))) ;
  			}
  			else if(cha >=97 && cha <=122){
  				sb.append("[") ;
  				sb.append(String.valueOf((char)(cha - 32))) ;
  				sb.append(String.valueOf(cha)) ;
  				sb.append("]") ;
  			}
  		}
  		return sb.toString() ;
  	}
  }
  //结果：
  //Start with : 我爱你abc我123
  //End with : 我爱你[Aa][Bb][Cc]我123
  

------ Solution ------------------------------------- -------
landlord just put lowercase becomes [ uppercase + lowercase ] do

  String str = "我爱你abc我123";
  StringBuilder sb=new StringBuilder();
  for(int i=0;i<str.length();i++){//循环字符串
     char c=str.charAt(i);
     if(Character.isLowerCase(c)){//当碰到小写的时候变成[大写+小写]
  	sb.append("["+Character.toUpperCase(c)+c+"]");
     }else{//其它情况直接添加
  	sb.append(c);
     }
  System.out.println(sb.toString());

search string, and then replace the abc [Aa] [Bb] [Cc]

; and I know so dry , singles I do not know how to write , you can write a demo I see no

I suggest not to use assic code conversion, because some Chinese characters also in the case of ASSIC code value intermediate

I suggest not to use assic code conversion, because some Chinese characters will be in the middle of sensitive aSSIC code value  

Thank pointing. However, I was also the first time I heard the Chinese characters in the ASCII code of the intermediate case . Detailed few examples can do ? Thank you !
