Write Code To Execute Before Main Method

[rashmi_ay]

Hello, I am learning Java programming language. And completed the course also. But, few days ago one of my friend told me to write the code which will execute before the main method and I was unable to do that. Can anyone tell me how to write a code which will execute before main method. Can anyone tell me how to write this particular code. I am waiting for your reply.

I don't think that this would be possible. As when you write any type of code first execution is done with the Main Method and then only you will able to get to execute all other line of code. So, it would be impossible to execute any type of code of line from the program which will able to execute before the Main method.

It may be possible as below done. Here your main method is defined into the Interface, which mean your interface is executed first and then your main method will execute.

public interface InterfaceMain
{
public class Main
{
public static void main(String [] args){
System.out.println("Main inside interface");
}
}
}

Yes, you can do that. If you don't provide any type of main method then also you can provide any message as below:

public class Trial
{
static 
{       
        System.out.println("Hello");
        System.exit(0);
}
}

I have searched for this on internet, but not find any type of solution for your problem. I think you need to make use of different books for getting solution for this purpose. I don't think that you will able to get any type of this information directly. You need to read books which will provide your tricks in java programming. For that you can make use of the Tricks of the Java Programming Gurus book also.

It is quiet simple to execute code before Main Method, you just need to use the static keyword in your program as below:

      static
      {
      //Provide your source code here
      }
