Thread: Can you guys help me fix my assignment

this is the program that i need to do

You are required to write a command line program in Java that declares three numbers.
Write a method called calc() that takes in the three numbers as parameters. Inside this
method, you must add the first two numbers together and divide the answer by the
third. The value of the sum must be returned. Write another method called display()
that prints the following to the screen:
******************************************
* *
* This is a simple program *
* that performs a mathematical *
* calculation. The answer is: *
* [answer] *
******************************************



so far i made this.

import java.util.Scanner;

public class assignmentB
{
public int calc(){

int number1;
int number2;
int number3;
int sum;

Scanner scan=new Scanner(System.in);

System.out.println("Please enter 1st number: ");
number1 = scan.nextInt();

System.out.println("Please enter 2nd number: ");
number2 = scan.nextInt();

System.out.println("Divide the sum of the two numbers by: ");
number3 = scan.nextInt();

sum = (number1 + number2)/ number3;

return sum;

}


public String display(){

System.out.println("****************************** ***");
System.out.println("* *");
System.out.println("* This is a simple program *");
System.out.println("* that performs a mathematical *");
System.out.println("* calculation. The answer is: *");
System.out.println("* "+ sum +" *");
System.out.println("* *");
System.out.println("****************************** ***");

}
}



can anyone fix this for me? so it will work as state above.

 import java.util.Scanner;
 
public class assignmentB
{
public int calc(){
 
int number1;
int number2;
int number3;
int sum;
 
Scanner scan=new Scanner(System.in);
 
System.out.println("Please enter 1st number: ");
number1 = scan.nextInt();
 
System.out.println("Please enter 2nd number: ");
number2 = scan.nextInt();
 
System.out.println("Divide the sum of the two numbers by: ");
number3 = scan.nextInt();
 
sum = (number1 + number2)/ number3;
 
return sum;
 
}
 
 
public String display(){
 
System.out.println("****************************** ***");
System.out.println("*                                                         *");
System.out.println("*        This is a simple program                 *");
System.out.println("*      that performs a mathematical           *");
System.out.println("*         calculation. The answer is:            *");
System.out.println("*                    "+ sum +"                        *");
System.out.println("*                                                         *");
System.out.println("****************************** ***");
 
}
}

basically my instructor wants me to make a program. his guidelines is this.

You are required to write a command line program in Java that declares three numbers.
Write a method called calc() that takes in the three numbers as parameters. Inside this
method, you must add the first two numbers together and divide the answer by the

Ok, that seems like a pretty straight forward assignment... What I would do:

1. Write a method that reads that users input;
2. Write a method that does that calculation, per the requirements;
3. Write a method that displays the result.

In the main method would call the methods in the order above... Done deal. The solution described would have less lines than what it took to write what I would do, but I am not a believer of giving the answers, but direction..

If you have specific questions, let me know, but to tell you the answer 100%, doesn't help you outside of satisfying your assignment, which is not the reason for taking thr class in the first place...

For starters, your calc method is supposed to allow three parameters into it, which it doesn't how it is written. Your instructor wants you to pass the three numbers into your calc method, not have your calc method do everything. It should look something like this.

public int calc(int num1, int num2, int num3) {
     //Do your calculations and return the result
}

You will also have to provide a main method to actually be able to call these methods and have it run in the console. Hope this helps.

Well, I would actually pass floats (and return) instead of ints, unless you need even further precision, where doubles would be used. But again three methods would be written in my solution.
