Question

Design a JAVA program with the class named Computer that creates a computer object that stores the computer's brand, model, memory (in GB) and storage (in GB). The class must contain the following instance variables and methods. All variable and method names must match the specifications listed below exactly.

Instance Variables:

- a String variable named brand
- a String variable named model
- an int variable named memory
- an int variable named storage

Methods:

The accessor and mutator methods for all four data fields. The names of the accessor (getter) methods must be the following:
- getBrand
- getModel
- getMemory
- getStorage

The names of the mutator (setter) methods must be the following:
- setBrand
- setModel
- setMemory
- setStorage.

Answer 1

public class Computer {

    private String brand;
    private String model;
    private int memory;
    private int storage;

    public String getBrand() {
        return brand;
    }

    public String getModel() {
        return model;
    }

    public int getMemory() {
        return memory;
    }

    public int getStorage() {
        return storage;
    }

    public void setBrand(String brand) {
        this.brand = brand;
    }

    public void setModel(String model) {
        this.model = model;
    }

    public void setMemory(int memory) {
        this.memory = memory;
    }

    public void setStorage(int storage) {
        this.storage = storage;
    }
}

class ComputerTest {

    public static void main(String[] args) {
        Computer computer = new Computer();
        computer.setBrand("Dell");
        computer.setModel("XPS-15");
        computer.setMemory(16);
        computer.setStorage(500);

        System.out.println("Brand: " + computer.getBrand());
        System.out.println("Model: " + computer.getModel());
        System.out.println("Memory: " + computer.getMemory() + " GB");
        System.out.println("Storage: " + computer.getStorage() + " GB");
    }
}
