Question

Create a program in Java that has the following functions:

add: which takes 2 input numbers and computes their sum

subtract: which takes 2 input numbers and performs their subtraction

multiply: which takes 2 input numbers and computes their product

divide: which takes 2 input numbers and performs their division

add3: which takes 3 input numbers and computes their sum

multiply3: which takes 3 input numbers and computes their product

All numbers can be considered doubles. In the main program perform all mathematical equations using the above functions to demonstrate their use. For example: double example1 = subtract(100, sum(multiply(2,4), divide(10,2) ) );

Explanation / Answer

Source code is below :

/*

class Test1
{
    public double add(double arg1, double arg2)
    {
        return (arg1+arg2);
    }
  
    public double subtract(double arg1, double arg2)
    {
        return (arg1-arg2);
    }
  
    public double multiply(double arg1, double arg2)
    {
        return (arg1*arg2);
    }
  
    public double divide(double arg1, double arg2)
    {
        return (arg1/arg2);
    }
  
    public double add3(double arg1, double arg2, double arg3)
    {
        return (arg1+arg2+arg3);
    }

    public double subtract3(double arg1, double arg2, double arg3)
    {
        return (arg1-arg2-arg3);
    }

    public double multiply3(double arg1, double arg2, double arg3)
    {
        return (arg1*arg2*arg3);
    }
  
}

public class Test
{
public static void main(String[] args)
    {
        Test1 t1 =new Test1();

       double example1 = t1.subtract(100, t1.add(t1.multiply(2,4), t1.divide(10,2) ) );
        System.out.println("Result is: "+example1);
    }
}

Output is :

Result is : 70
