Create a package MCA which will have 2 classes as class Mathematics with a methods to add two numbers, add three float numbers and class Maximum with a method to find maximum of three numbers.

package MCA;
import java.io.*;
class Mathematics
{
    float a,b,c;
    int p,q;
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

    public int add_i()
    {
        try
        {
        System.out.println("Enter two integers");
        p=Integer.parseInt(br.readLine());
        q=Integer.parseInt(br.readLine());
        }
        catch(Exception ex){}
        return (p+q);
    }

    public float add_f()
    {
        try
        {
        System.out.println("Enter three floats");
        a=Float.parseFloat(br.readLine());
        b=Float.parseFloat(br.readLine());
        c=Float.parseFloat(br.readLine());
        }
        catch(Exception ex1){}
        return (a+b+c);
    }
}

class Maximum
{
    int x,y,z,max;
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

    public int check_max()
    {
        try
        {
        System.out.println("Enter three integers");
        x=Integer.parseInt(br.readLine());
        y=Integer.parseInt(br.readLine());
        z=Integer.parseInt(br.readLine());
        if(x>y&&x>z)
            max=x;
        else if(y>z)
            max=y;
        else
            max=z;
        }
        catch(Exception ex3){}
        return max;
    }
}


class Test
{
    public static void main(String args[])
    {
        Mathematics m=new Mathematics();
        System.out.println("Addition of two integers is "+m.add_i());
        System.out.println("Addition of three floats is "+m.add_f());
        Maximum m1=new Maximum();
        System.out.println("Maximum amongst three integers is "+m1.check_max());
    }
}



D:\Rushi>javac -d D:\Rushi Test.java
D:\Rushi>java -cp D:\Rushi MCA.Test
Enter two integers
20
30
Addition of two integers is 50
Enter three floats
12.5
52.2
36.4
Addition of three floats is 101.1
Enter three integers
2
5
8
Maximum amongst three integers is 8
