    You need a static void main() function that creates an instance of the IfExamples class. The main() function can then call the Example1 method with values that you want to test.

    The main() function can be in a separate class in a separate file that is part of your project, or it can be in the same class that you are testing.

    Here's how the IfExamples file can be organized if you want to put the main method in the same class and in the same file:
    //
    //IfExamples.java
    //
    public class IfExamples 
    {
        public IfExamples() {}
     
        public void Example1(int x)
        {
     
            //
            // The stuff that you already have;
            //
     
        } // End of Example1 method
     
        public static void main(String [] args) {
     
            // Create an IfExamples object
            IfExamples example = new IfExamples();
            //
            // Call example.Example1(x) with the values of x that you want to test
            //
     
        } // End of main method
    } // End of IfExamples class definition


    Cheers!

    yes, you need the public static void main(String args[]) to run the program.
    Any Reply is Appreciated
