Why is it not able to compare my input and the values from the database ??
I have also printed the values I got from the database after taking the input so that I can compare the input and the database value .
This is the java code :
public static void clogin(String username, String password) throws Exception {
String url = "jdbc:mysql://localhost:3306/Bank";
String query = "select * from admin_credentials";
String uname = "###";
String passw = "###";
Class.forName("com.mysql.cj.jdbc.Driver");
Connection con = DriverManager.getConnection(url,uname,passw);
Statement st = con.createStatement();
ResultSet rs = st.executeQuery(query);
while (rs.next()) {
String un = rs.getString(1);
String pw = rs.getString(2);
System.out.println(un + " " + pw);
if (un == username && pw == password) {
System.out.println("Login Successful!!");
}
else {
System.out.println("Invalid Credentials");
}
}
st.close();
con.close();
}
public static void main(String[] args) throws Exception {
Scanner input = new Scanner(System.in);
System.out.println();
System.out.println("Username : ");
String username = input.next();
System.out.println("Password : ");
String password = input.next();
clogin(username,password);
}
}
My Database :
Username : kushaltodi
Password : epson
My Output :
Username :
kushaltodi
Password :
epson
kushaltodi epson
Invalid Credentials
