When I input a string of 4500 characters followed by a newline feed in Java console, it displays input line is too long runtime error in the terminal.
I have tried using both Scanner and BufferedReader, but no success.

Have you tried putting the `String` in a file first and read it from there? – Frank Andres Apr 11 '15 at 17:15

Is there any line breaks in the String input? Or is it a continuous String of text? – user3437460 Apr 13 '15 at 05:27

My advice when working with big strings is to use StringBuilder Class, here is an example:
import java.util.*;
public class Main {
public static void main(String[] args) {
String someString;
Scanner scanner = new Scanner(System.in);
StringBuilder builder = new StringBuilder();
builder.append(scanner.nextLine());
someString = builder.toString();
System.out.println(someString);
}
}

What if input contains continuous spaces or tabulators? `next()` will ignore them. – Pshemo Apr 11 '15 at 17:26

Sorry I didn't get your question firstly, if you want not to ignore them you should change scanner.next() with scanner.nextLine() – Shota Apr 11 '15 at 17:38

StringBuilder builder = new StringBuilder(); //sumit = ab.nextLine(); for (int jc=0;jc
