1. Void Main Not Working Dev C++ Windows 7
2. Void Main Not Working Dev C 2b 2b 1b

Hi friends welcome to santra techspot i explained how to solve source file not compiled error in dev c compiler.dev c is a good software to write. C was originally designed to support only single thread programming. In every application, there is one default thread. The execution control would go straight to the main function (entry point for default thread), the program would execute in a pretty much sequential manner (one computation would complete before the next starts), and end of the story. Am a new c programmer. I refer to the code ' Bouncing Ball' which is a GUI, now there is a rectangle created, i managed to change the color the rectangle in the main window and what my may problem is how to make the rectangle fixed and not only increase to be a full rectangle after the ball has hit both ends, how do i achieve that?

My homework tells me to do this....

a. Create a class named Purchase. Each Purchase contains an invoice number,amount of sale, and amount of sales tax. Include set methods for the invoicenumber and sale amount. Within the set() method for the sale amount, calculatethe sales tax as 5% of the sale amount. Also include a display method that displaysa purchase’s details. Save the file as Purchase.java.

b. Create an application that declares a Purchase object and prompts the userfor purchase details. When you prompt for an invoice number, do not let theuser proceed until a number between 1,000 and 8,000 has been entered.When you prompt for a sale amount, do not proceed until the user has entereda nonnegative value. After a valid Purchase object has been created, displaythe object’s invoice number, sale amount, and sales tax. Save the file asCreatePurchase.java.

This is what I have so far......

Why isn't this working?

because you haven't called anything in main method. Your main method is empty.

What is 'Public Static Void Main' in Java?, method within the Java application. It's the core method of the program and calls all others. It can't return values and accepts parameters for complex command-line processing. On systems that doesn’t provide such a facility the return value is ignored, but that doesn’t make “void main()” legal C++ or legal C. Even if your compiler accepts “void main()” avoid it, or risk being considered ignorant by C and C++ programmers. In C++, main() need not contain an explicit return statement.

Why main is public static void method in Java?, Why is the main method in Java qualified as public static and void? My homework tells me to do this. a. Create a class named Purchase.

1)Do you get any compile time error?Method invocation of java search for main method to execute but in the current main method, It does not have anything to execute or NIL calls

So nothing will be executed.Call the methods from the main method with the required inputs so that main methods will execute with the call invocation.

public static void main(String[] args) - Java main method, , since it must be called by code outside of its class when the program is started. Static methods are the method which invokes without creating the objects, so we do not need any object to call the main() method. void: In Java, every method has the return type. Void keyword acknowledges the compiler that main() method does not return any value. main(): It is a default signature which is predefined in the JVM. It is called by

What does 'public static void' mean in Java?, Method signature is wrong. It should be public static void main(String [] args)​throws IOException instead of static void main()throws The Startup class. ASP.NET Core apps use a Startup class, which is named Startup by convention. The Startup class:. Optionally includes a ConfigureServices method to configure the app's services.

public static void main() not working?, Every word in the public static void main statement has got a meaning to the JVM. Error: Main method not found in class, please define the main method as: public As soon as the main() method terminates, the java program terminates too.

In the above example, we are creating 3 Thread objects and 2 String objects. In the first comparison, we are checking that t1 t3 or not. As we know that both t1 and t3 pointing to same object that’s why it returns true.

• You have an empty main method and you expect something to happen in your program? Its like giving you no assignments to do and then being surprised that you haven't done any assignment.
• I think your core mistake is CreatePurchase extends Purchase - there is no reason the purchase creator should extend the Purchase class.
• one of best answers in SO ever... xDDDDDD
• @JordiCastilla I use sarcasm a lot, but I'm not sure I've understood it this time :D :D
• it's simple, effective and IMHO super funny answer... not sarcasm for the answer itself, but the powerful meaning of it ;)
• you can merge both answers.
• all of these have given me multiple errors......can you guys please not make me feel stupid, i know this is probably stupid but can you just show me?
• It would be nice if you could merge both of your answers Mohan.
• Thanks Prasad.. Jose check the modified code above with the sample input and output
