Answer 1

Dear Student,

Here i have written the two Java programs for each equation...

NOTE: Please note that the following programs have been tested in an online compiler.

Program:1

-----------------------------------------------------------------------------------------------------------------------------------------

import java.util.Scanner;

public class CollectionTest {

    public static void main(String args[]) {
   
        int x = 20;
  
        int y = 10;
  
   
        //adding two numbers in Java by calling method
      
       System.out.printf(" Addition of numbers %d and %d is %d %n", x, y, sum(x,y));
     
        //Multiplying two numbers in Java by calling method
      
       System.out.printf(" Multiplication of numbers %d and %d is %d %n", x, y, mul(x,y));
      
        //Division of two numbers in Java by calling method
       System.out.printf(" Division of numbers %d and %d is %d %n", x, y, div(x,y));
     
     
    }

    public static int sum(int x, int y)
  
    {
  
      
    return x + y;
  
    }
  
    public static int mul(int x, int y)
  
    {
  
      
    return x * y;
  
    }

    public static int div(int x, int y)
  
    {
  
      
    return x / y;
  
    }
}

------------------------------------------------------------------------------------------------------------------------------------------

Here i have attached the output of the program as a screen shot...

Output:1:

-------------------------------------------------------------------------------------------------------------------------------------

Output: Addition of numbers 20 and 10 is 30 Multiplication of numbers 20 and 10 is 200 Division of numbers 20 and 10 is 2

--------------------------------------------------------------------------------------------------------------------------------------------

program2:

===============================================================

import java.util.Scanner;

public class CollectionTest {

    public static void main(String args[]) {
   
        int x = 0;
        int y = 3;
      
        double w = 4.1;
      
        double q = 2.0;
  
   
        //adding two numbers in Java by calling method
      
       System.out.printf(" Addition of numbers %d and %d is %d %n", x, y, sum(x,y));
     
  
       System.out.printf(" Addition of numbers %f and %f is %.1f %n", w, q, sum(w,q));
     
     
    }

    public static int sum(int x, int y)
    {
      
    return x + y;
  
    }
    public static double sum(double w, double q)
    {
      
    return w + q;
  
      
    }

  
}

-----------------------------------------------------------------------------------------------------------------------------------

Here i have attached the output of the program as a screen shot...

Output:1:

-------------------------------------------------------------------------------------------------------------------------------------

Output Addition of numbers 0 and 3 is 3 Addition of numbers 4.100000 and 2.000000 is 6.1
