Hi all..i'm urgently need any attention here..pliz help to solve this problem..
The description of my problem is like dis >> let say now i have 100 length of a text. Now , i need to break it into multiple parts, accordingly to the max lenght of a part for one time is 30.So, it should be to returned like dis >>
text [1]="blablabla.." -->text.length =30
text [2]="blablabla.." -->text.length =30
text [3]="blablabla.." -->text.length =30
text [4]="blablabla.." -->text.length =10
I have write a pieces of code that may explain what i try to do..but its not really work..i hope anybody out there can help me..thanks a lot..
code:
          for (int i=0; i<fullMsg.length(); i++){
               singlLen ++;
          if (singlLen == LEN-1){
                    System.out.print("splitMsg: i="+i+"\n");
                    System.out.print("splitting new msg["+msgCnt+"]="+fullMsg.substring(beginPos, i)+"\n");
                    msg[msgCnt] = fullMsg.substring(beginPos, i);
                    singlLen = 0;
                    msgCnt ++;
                    beginPos = i+1;
               }

Answer 1

     public static void main(String[] args) {
          String LONG = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
          int MAX_LEN = 30;
          ArrayList<String> strList = new ArrayList<String>();
          int i = 0;
          while (i < Math.floor(LONG.length() / MAX_LEN)) {
               strList.add(LONG.substring(i * MAX_LEN, MAX_LEN * (i + 1)));
               i++;
          // now get the remainder
          i--; // decrement it to get how many MAX_LEN chunks we have
          int remainder = LONG.length() % MAX_LEN;
          strList.add(LONG.substring(MAX_LEN * (i + 1), MAX_LEN * (i + 1)
                    + remainder));
          System.err.println(strList.toString());
     }I'm not sure if this is what you want... Say you have 75 chars in string.
Prepares an array with 3 strings,
first len 30,
second len 30,
last len 15
makes 75 in total
