How can I create an utility class?

Question

Can anyone help me how I can able to create a class using utility methods, what is the best approach to do it?

Answer 1

You can take the below code as a reference to make a utility method:

public final class ExampleUtilities {

    // Example Utility method

    public static int foo(int i, int j) {

        int val;

        //Do stuff

        return val;

    }

    // Example Utility method overloaded

    public static float foo(float i, float j) {

        float val;

        //Do stuff

        return val;

    }

    // Example Utility method calling private method

    public static long bar(int p) {

        return hid(p) * hid(p);

    }

    // Example private method

    private static long hid(int i) {

        return i * 2 + 1;

    }

}

I hope this will help.
