Loop isn't breaking when a specific string is inputted

Question

When the user inputs pBreak, it should break the while loop. However, this isn't working and I'm confused on why. Could somebody please help me?

package main;

import java.io.*;
import java.util.*;

public class TextFiles {
    public static void main(String[] args) {
        try {
            BufferedWriter out = new BufferedWriter(new FileWriter("file.txt"));
            Scanner input = new Scanner(System.in);
            while (true) {
                String line = input.next();
                if (line == "pBreak") {
                    break;
                }
                out.write(line);
                out.newLine();
            }
                out.close();
        } catch (IOException e) {
            System.out.println("Error!");
        }
    }
}

Answer 1

Use equals instead of ==. Consider, null-safe equals

 if ("pBreak".equals(line)) {

Answer 2

This code will also work:

if (line.equals("pBreak")) {
    break;
}

Answer 3

== operator will compare the references of the two operands. As line variable is a different string object's reference ,it will not match to string literal constant reference pBreak while comparing.

if (line .equals("pBreak")) {
  break;
}

So equals() method has to be used to compare the String.enter code here

Answer 4

Change:

if (line == "pBreak") {

to

if (line.equals("pBreak")) {

== compares object references, .equals(String) compares String values.
