how to fill the string to length = 256

[Guest]

Now, I am using below code, how to fill the string to length = 256 or more ?
inputLine = inputLine.substring(0,inputLine.length()) +
" " +
" " +
" "


/* decode 23.18.14

javac decode_mrp.java

*/
import java.io.*;

public class decode_mrp {
public static void main(String[] args) throws IOException {
String inputLine , outputLine;
String item,site;
BufferedReader in
= new BufferedReader(new FileReader(args[0]));

while ((inputLine = in.readLine()) != null) {

inputLine = inputLine.substring(0,inputLine.length()) +
" " +
" " +
" "
;
// System.out.println(inputLine.substring(2,14) + "<");
if (inputLine.substring(2,14).equals("Item Number:")) {
item = inputLine.substring(15,29);
site = inputLine.substring(121,129 );
System.out.println(item + " " + site);

}
}

}

}

Thank. It works

public final class test_string {
public static void main(String[] args) {
String s = new String("eric");
s = s + rep(' ',10) + "<";
System.out.println(s);
}


public static String rep(char c, int count) {
char[] s = new char[count];
for (int i = 0; i< count ; i++) {
s = c;
}
return new String(s).intern();

}

}
