Whenever I input the correct username and password it says incorrect username or password.
package taskperf6;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Scanner;
public class TaskPerf6 {
public static void main(String[] args) {
// TODO code application logic here
Scanner input = new Scanner(System.in);
System.out.println(" Welcome! ");
System.out.println("");
System.out.println("-Please choose between 1 & 2-");
System.out.println("-1. Register -");
System.out.println("-2. Login -");
int choice = input.nextInt();
input.nextLine();
System.out.println("Your choice:" + "[" + choice + "]");
System.out.println("");
BufferedWriter writer = null;
if (choice == 1) {
try {
System.out.println(" R E G I S T E R ");
System.out.print("Hi! Please input your desired username: ");
String username1 = input.nextLine();
System.out.println("");
System.out.print("Hi! Please input your desired passowrd: ");
String password1 = input.nextLine();
writer = new BufferedWriter(new FileWriter("C:\\Users\\Administrator\\Documents\\NetBeansProjects\\Temp File\\TaskPerf6_Temp\\records.txt", true));
writer.write("\nUsername: " + username1 + " | " + " Password: " + password1);
System.out.println("");
System.out.println("You have successfully registered!");
System.out.println(" Welcome! " + username1);
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (writer != null) {
writer.close();
}
} catch (IOException e) {
}
}
} else if (choice == 2) {
System.out.println(" L O G I N ");
System.out.print("Enter your username: ");
String usernameLog = input.nextLine();
System.out.print("Enter your password: ");
String passwordLog = input.nextLine();
try (Scanner scan = new Scanner(new File("C:\\Users\\Administrator\\Documents\\NetBeansProjects\\Temp File\\TaskPerf6_Temp\\records.txt"))) {
while (scan.hasNextLine()) {
String line = scan.nextLine();
if (line.contains(usernameLog + " | ")) {
String[] parts = line.split(" \\| ");
if (parts[1].trim().equals(passwordLog)) {
System.out.println("Successfully logged in!");
return;
}
}
}
System.out.println("Incorrect username or password.");
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
The output of the code (Login)
I have no problems regarding in the registration it's just on the login part.
