Question

What would an example of java code look like?

Producer class

- Declaring toolsPerHour as an instance variable

- Creating constructor that takes toolsPerHour

- Creating getter for toolsPerHour

- Method for calculating days produced

Tester class

- Creating 3 producer objects using constructor

- Setting toolsPerHour

- Calling methods

- Displaying output

public class Producer {

    // Declaring toolsPerHour as an instance variable
    private int toolsPerHour;

    //- Creating constructor that takes toolsPerHour
    public Producer(int toolsPerHour) {
        this.toolsPerHour = toolsPerHour;
    }

    //- Creating getter for toolsPerHour
    public int getToolsPerHour() {
        return toolsPerHour;
    }

    //- Method for calculating days produced
    public int days(int tools) {

        if (toolsPerHour != 0) {
            // assumping the plan operates 8hrs a day
            int totalHoursNeeded = tools / toolsPerHour;
            return totalHoursNeeded / 8; // return the number of days
        } else {
            return 0;
        }
    }
}

public class Tester {

    public static void main(String[] args) {
        //- Creating 3 producer objects using constructor
        Producer one = new Producer(10); // Setting toolsPerHour to 10
        Producer two = new Producer(20); // Setting toolsPerHour t0 20
        Producer three = new Producer(50); // Setting toolsPerHour to 50

        //- Calling methods
        //- Displaying output
        System.out.println("Days needed to produce 1000 tools by Producer 1 = " + one.days(1000) + " days");
        System.out.println("Days needed to produce 1000 tools by Producer 2 = " + two.days(1000) + " days");
        System.out.println("Days needed to produce 1000 tools by Producer 3 = " + three.days(1000) + " days");


    }
}
