Ho to solve this problem using java

A couple of for loops could handle this:

e.g.

class Splitter {
	public static void main(String[] args) {
		String input = "01234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890012345678900123456789001234567890";

		for (int counter = 0; counter < input.length(); counter++) {
			for (int line = 1; line <= 10; line++) {
				System.out.print("Line " + Integer.toString(line) + " : ");

				if (counter < input.length()) {

Thanks Kufmed, it is ver helpful, I have to add it each line in an xml element.  How do I do that?

startElement("p_text");
            addNode("type", 2);
            String notes = getNotes();
            if(null!= notes){
                  System.out.println("Notes Length is " +notes);
                  for(int counter=0; counter<=notes.length();counter++){
                        for (int line = 1; line <= 10; line++) {
                              addNode("textine" + line , text will go here inside a node );
                              
                        }      
                  }

            }

            endElement("p_text");

      }


 protected void addNode(String name, int data) throws SAXException {
            addNode(name, String.valueOf(data));
    }

I'm not exactly sure of your requirements. If we change the single line length limitation to 4 and the total line limitation to 40 in your example (just to make it easier for testing), then a string of 13 characters, say 'abcdefghijklm' should produce the following 10 lines?:
1-4   abcd
5-8   efgh
9-12  ijkl
13-16 m
17-20 blank
21-24 blank
25-28 blank
29-32 blank
33-36 blank
37-40 blank

And a string of 50 characters, say 'abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwx',   should produce the following lines?:

1-4   abcd
5-8   efgh
9-12  ijkl
13-16 mnop
17-20 qrst
21-24 uvwx
25-28 yzab
29-32 cdef
33-36 ghij
37-40 klmn

and also the folloowing lines?:
41-44 opqr
45-48 stuv
49-52 wx
53-56 blank
57-60 blank
61-64 blank
65-68 blank
68-72 blank
73-76 blank
77-80 blank

If that's correct, then what do you want to do with them? Also, what is meant by including space? If that's not correct, can you provide a little more clarification. Perhaps some actual data and the anticipated output.

this is exactly what i needed
