以相反的方式将每个字符串存储在句子中

Question

i try with buffered string.reverse(); but i want reverse each word of sentence. so i try with this..

 for(int a = 0;a <= msgLength; a++){
           temp += msg.charAt(a);
           if((msg.charAt(a) == '')||(a == msgLength)){
           for(int b = temp.length()-1; b >= 0; b--){
               encrypt_msg += temp.charAt(a);
               if((b == 0) && (a != msgLength))
                   encrypt_msg += "";
           }
           temp = "";
       }
       }

plz help me to simplify this logic. string is user defined. i wanted to print reversed string in jtextfields.

Answer 1

Try following simple code:

String sentence= "This is sentence";
String[] words=sentence.split(" ");
for(String word: words){
 System.out.println(new StringBuilder(word).reverse());
}

Answer 2

there is a method named split()

you can separate the tokens using this method like this.

String s = "hello how are you";
String[] s2 = s.split(" ");

now s2 contains each word as array element.

now you can reverese by traversing the array.

Answer 3

there your answer...

StringTokenizer st = new StringTokenizer("this is a test"); String strRev="";

    while (st.hasMoreTokens()) {
     StringBuffer revers=new StringBuffer(st.nextToken());
     strRev=strRev+" "+revers.reverse().toString();
 }

try it..!!
