weird problem with println

hello, i have this weird problem, i built a method to replace all non letter charecters with blank space, when i put small string it works perfectly, but when i put large string into it, it wont print the result (system.out.println), but when i place the method output into txt file, it writes it just fine . but later when i try println from the file it wont print either.

here's the method, maybe you can tell me what i'm doing wrong

Code:

---

public static String clearTokens(String text){
               
                String lowerCase = text.toLowerCase();
               
                StringBuilder buf = new StringBuilder( text );
               

                for(int i = 0 ; i< lowerCase.length() ;i++ ){
                        if((lowerCase.charAt(i)< 'a') || ( lowerCase.charAt(i)>'z' )){                               
                                buf.setCharAt(i,' ');
                    }
                                               
                }
               
                return buf.toString();               
        }

i need this method to clear special chars from downloaded url.
the input is about 50000 chars

thank you for any help...

If you are running the program from within an IDE it might object to a line 50k characters long.

Eclipse certainly does. The following creates a one line file but nothing appears in the IDE's console.

Code:

---

import java.io.File;
import java.io.FileWriter;

public class StringCleaner {
    public static void main(String[] args) throws Exception {
        StringBuilder buf = new StringBuilder();
        for(int i = 0; i < 50000; i++) {
            char ch = (char)('a' + (i % 26));
            buf.append(ch);
        }
        System.out.println(buf);
        FileWriter out = new FileWriter(new File("c:/longString.txt"));
        out.write(buf.toString());
        out.close();
    }
}

thanks,
i use eclipse, i tought so to, but the weird thing is, when i try to print the original string with the special chars, it prints it just fine on screen, but when i clean the string with this method, it goes crazy, and wont show me a thing on screen, tried to run it in debug step by step, at first all works fine, but something in the loop makes him go crazy :confused:

thanks for the replay anyway, i think i'll just split the string to array, and run cell by cell :o
