java - Using Switch and Try Statement to Validate user Input -

I am working on it for a while and will not compile it. It tells me an error

switch variable option (^) ^ may not have been ^ ^
but I have that variable in the program Set up. So I do not know what the problem is? Is it really something else that is keeping it from the compilation? Import java.io. *; Import javax.swing.JOptionPane; Public Class MyType {Public Static Zero Main (String [] Args) {String Strawwise = "", Stratry String, Strategy Init, Strategy Double; Integer options, tryInt; Repeat the double try; Boolean did = wrong; While (! Done) {try {string reply = joppenpane.shownputdream (empty, "what is my type \ n \ n \ n1) string \ n2) integer \ n3) double \ n4) Skip program"); Choice = integer Parasont (Stroshowice); // Examination for valid code of 1, 2, 3, or 4 (if option & lt; 1; option & gt; 4) New Number Format Suggestions (); Others did = true; } Hold (Number Format Exception E) {JOptionPane.showInputDialog (blank, "Please enter 1, 2, 3, or 4", "Error", JOSEPHEN.INFORMATION_MESSAGE); Switch (Preferred) {Case 1: Javanpanpan. Show Messagidoug (empty, "right, any input can be saved as a string"); break; Case 2: Jobpaction. Show message dialects (empty, "right!"); TryInt = integer Paracetrain (Stroshouis); break; Case 3: Jobpaction.

Integrate flash games in android app? -



    3 is a flash game that I want to integrate into a menu / list in the Android app. So when the user selects the game from the list, the game starts with the help of the Android Flash Player.   Is it better or better with webwave?   Is there any good tutorial?   Thank you! Adobe Flash provides a good way: you can create a breeze for the Android app.    Use this to create your menu and compile three games in your air app.   Here are some tutorial links about how to publish AiI for Android applications and:   PART1: AIR for Android, PART2:   Publication for Android apps: Ai:   I do not believe that the Android Flash Player can be launched with a single intention so far, so using Java Android will not solve it (now ) And   and a third approach Whatever you mentioned, it should work - using the webwave.
