Question

Take your code from Assignmnet#4 Task 1 and Task 2 change the source code to reflect an object orientated model for programming. Use Constructors, Parameters, and arguments as needed. Write a program that has 2 methods. 1 method will convert Seconds into minutes 1 method will convert seconds to hours, minutes, and seconds Use the modulus arithmetic symbol for part of the calculation/conversion if you like. Outpute Show number of seconds, conversion to minutes, and remaining seconds. or Show number of seconds, converted to hours, converted to minutes, and remaining seconds.

All information about the question (Task 1 and task 2) are down below

Programming Assignments

Task 1 –

Page 39. in Programming A Comprehensive Introduction

Update your program from Assignment 2, Task #2

Allow the user to input their weight for the earth weight to moon weight conversion problem. Add an ifstatement that prompts the user if she inputs 0 or a negative number for her earth weight.

#13. Mars’ gravity is about 17 percent less that of the earth’s. (Meaning you weigh less on the moon). Write a program that computes your affective weight on Mars.

P9. 29 in book

2nd Task: Write a simple program displaying knowledge of if conditional statements and using the Scanner input method.

Create 2 input integer (int) variables. The input numbers should not be set by the programmer but entered by the user.

Have 2 simple equations that solve for a the variable ( c ).      c = a – b    and    c = b – a

Create statements for if (c) is a negative or non-negative number for each equation.

Display the possible outputs for in each equation.

Please enter an integer:               //Prompt the user

7                                  // Integer entered by the user not by the programmer.

Please enter an integer:               //Prompt the user

9                                  // Integer entered by the user not by the programmer.

a = 7                           // display the value of a

b = 9                                       // display the value of b

a is less than b                    // display the difference the relationship between and b

// Create space between each output

c = a – b                              

c = -2

c is negative             //create a statement stating whether c is negative or positive.

c = b - a

c = 2

c is non-negative

If Else Ladder Example and Scanner Class Demo. Scanner is a class which is used to read the input from the keyboard. Here we read the value of n from the keyboard and display the result using if else ladder. import java.io.*; import java.util.*; public class IfElseIfLadder { public static void main(String args[]) { int n; System.out.println( " Enter the value of n- n=1 Hello, n=2 Hi, n=3 Good else No Match Found"); Scanner s =new Scanner(System.in); // read the value of n using the keyboard n=s.nextInt(); if(n==1) { //This block will be executed only if "n" is equal to 1 System.out.println("Hello"); } else if(n==2) { //This block will be executed only if "n" is equal to 2 System.out.println("Hi"); } else if(n==3) { //This block will be executed only if "n" is equal to 3 System.out.println("Good"); } else { System.out.println("No Match Found"); } } } Output: Enter the value of n- n=1 Hello, n=2 Hi, n=3 Good else No Match Found 3 Good. program displaying knowledge of if conditional statements and using the Scanner input method. import java.io.*; import java.util.*; public class Scanner_Demo { public static void main(String args[]) { int a,b,c; System.out.println(" Enter the values a and b"); Scanner s = new Scanner(System.in); a=s.nextInt(); b=s.nextInt(); System.out.println(" Value of a is : " +a);   System.out.println(" Value of b is : " +b); if (a<b)   System.out.println(" a is less than b"); else System.out.println(" a is greater than b"); c=a-b; System.out.println(" Value of c=a-b is : "+ c); if(c>0)   System.out.println(" Value of c is positive"); else System.out.println(" Value of c is negative"); } } Output: Enter the values a and b 3 1 Value of a is 3 Value of b is 1 a is greater than b Value of c=a-b is 2 C is positive

}
public static void main (String[] args) throws java.lang.Exception
   {
   int n;
   Scanner s =new Scanner(System.in);
   System.out.println("Enter Seconds : ");
   n=s.nextInt();
   Codechef obj=new Codechef();
   obj.convertToMinutes(n);

   }
   void convertToMinutes(int s)
   {
   System.out.println("---------------CONVERSION TO MINUTES----------------");
   System.out.println("Seconds before Conversion : "+s);
   minutes=s/60;

   System.out.println("Seconds before Conversion : "+s);
   minutes=s/60;
   hours=minutes/60;
   minutes=minutes%60;
   seconds=s%60;
   System.out.println("Hours after Conversion : "+hours);
   System.out.println("Minutes after Conversion : "+minutes);
   System.out.println("Seconds after Conversion : "+seconds);
   }
}

OUTPUT

Console View Applet View Log View Enter Seconds 3661 CONVERSION TO MINUTES---- Seconds before Conversion 3661 Minutes after Conversion 61 Seconds after Conversion 1 Seconds before Conversion 3661 Hours after Conversion:1 Minutes after Conversion 1 Seconds after Conversion 1
