    Default quick question

    Greetings,

    I'm completely new to programming and thought I might give java a try.

    I'm trying to write a program that gets a password from a user. It will then be tested against a password stored in a string. I want to use a while
    loop that will repeat until the user gets the correct password.

    When I use an online compiler, it doesn't execute for me. Am I on the right path? The code is as follows...

     
    import javax.swing.JOptionPane;
    public class Password
    {
    	public static void main(String[] args) 
    	{ 
    		String yourpass, mypass;
    		mypass = "happy";
    		boolean b = false;
     
     
     
     
    		 while(!b)
     		 {
    			yourpass = JOptionPane.showInputDialog(null, "Enter password: ");
     
    			if(yourpass.equals(mypass))
    		  {
    			JOptionPane.showMessageDialog(null, "Correct password!");
    			b = true;
     
    		  }
    		  else
    		  {
    			JOptionPane.showMessageDialog(null, "Incorrect password!");
     
    	      }
            }
        }
    }
    Thank you for any sugggestions,
    Jim

    Why on earth do you use an online compiler? Compile it yourself. BTW, it looks OK, apart from the indentation.

    Just ran your code in Eclipse and it worked perfect. What online compiler are you using and what kind of errors are you getting?

    I was using compileonline and it was hanging on the executing of the file.

    is my indentation okay... outside of the curlys lining up?

    I will look at eclipse. Is this the one I install?

    Eclipse IDE for Java EE Developers.

    Thank you for the replies.

    You just need a JDK and an editor (e.g. Notepad++) to start. Learning to use eclipse is a completely different thing. You should be able to compile and run from the command line, learn the pitfalls of path, classpath and packaging, before using an IDE. It hides all that stuff, that you sooner or later have to know.

    Complete shenanigans! I've been a software engineer for 6 years and have never coded via command line. And furthermore, learning an IDE like Eclipse is crazy easy, there are many tutorials on the basics on youtube. I agree learning the basics of paths and packaging are a good idea, but that's not typically something you learn when you first start programming.
