Hi This is a dummy text

To reach the line where the actual problem is

REPLACE==ZZZZ== by ==WORK==

Hi1 ZZZZ at TCS

The ZZZZING HOURS are from 9AM TO 6PM

REPLACE OFF

This marks the replace off so do not replace text after this

testing ZZZZ

it should still stay ZZZZ



Finding Solution

import java.io.File;

import java.io.IOException;

import java.util.*;



class base{

public static void main(String[] args) throws IOException {

Scanner sc = new Scanner(new File("file.txt"));

sc.useDelimiter("\n");

while (sc.hasNext()) {

String s = sc.next();

if (s.trim().isEmpty()) {

continue;

}

String ip = s;

System.out.println(ip);



// String text= new String(ip);

// String[] sentences = text.split("\\.");

// System.out.println(Arrays.toString(sentences));

// String[] sen = Arrays.toString(sentences);

// String op = ip.replace("ZZZZ", "WORK");

}

}
