1. Create a package P and within that package create class PackClass which have method called findmax( ) which find maximum value from three numbers. Now import the package within another class DemoClass and now display the maximum number.

/* file 1 Packclass.java */

package P;

public class Packclass

{

    public int findmax(int a,int b,int c)

    {

        int max = (a>b)? ((a>c)? a:c) : ((b>c)? b:c);

       

        return max;

    }

}

/* file 2 Program1.java */

import P.Packclass;

import java.util.*;

class Program1

{

    public static void main(String args[])

    {

        Packclass p1 = new Packclass();

        Scanner sc = new Scanner(System.in);

       

        System.out.print("enter three number: ");

        int a = sc.nextInt();

        int b = sc.nextInt();

        int c = sc.nextInt();

       

        System.out.println("\nmaximum number is: "+ p1.findmax(a,b,c));

       

    }

}
