Username And Password In Java Code

Username And Password In Java Code

In this article we will show you the solution of username and password in java code, in most cases, the terms "username" & "password" relate to the credentials needed for authentication. A "username" is a special label given to a user, & a "password" is a code used to confirm that person's identity.

These words are frequently used as variable names in Java programming to denote the values supplied by a user for verification.

To check if the supplied credentials are legitimate, the code may compare the input values of the "username" & "password" variables with predetermined values or check them against a secure data source.

The security and integrity of a system or application depend on the proper handling and storage of user names and passwords.

We'll talk about the username and password concepts in Java programming now.

Step By Step Guide On Username And Password In Java Code :-

import java.util.*;
public class Tk
 public static void main(String args[])
  String user_name = "Talkerscode";
  String password = " Talkerscode ";
  if(user_name.equals("Talkerscode ") && password.equals("Talkerscode "))
   System.out.println("Authentication Successful");
   System.out.println("User name/ Password not matching");
  1. The login information and the password are written within the Java code, as you can see.
  2. Importing the Java utility package enables the programme to use classes like Scanner for input. Our code begins with the import statement "import java.util.*;".
  3. Then, we use the "public class" keyword along with the class name "Tk" to declare a public class with the name "Tk".
  4. The main method is then defined.
  5. The Java program's main function is called "public static void main(String args[])" and serves as its entry point.
  6. It accepts string input arguments in the form of an array.
  7. Next, variables are declared and set to initial values. Two String variables named "user_name" & "password" are defined and initialised with the words "Talkerscode" and "Talkerscode," respectively.
  8. After that, a "if" statement is used to determine whether the "user_name" and "password" input values match the hardcoded values.
  9. The String values are then compared using the ".equals()" method, which compares the contents of the strings instead of their memory addresses.
  10. The programme prints "Authentication Successful" using the "System.out.println()" method if the input values match the encoded values. If not, "User name/Password not matching" is displayed.
  11. Closing braces within the if-else block & the main method are then used to signify the end of the code.

Conclusion :-

As a result, we were able to learn about the password and username in Java code.

Additionally, we discovered how to compare user input with a hardcoded username and password using an if statement, which then generates the appropriate output based on the comparison's results.

It illustrates how to use String variables, compare strings using the ".equals()" function, and publish output to the console using the "System.out.println()" method.

I hope this article on username and password in java code helps you and the steps and method mentioned above are easy to follow and implement.
