Question

I am somewhat new to JAVA. I’ve been working with it in college, but I have to admit, my instructor is of absolutely no help. She hardly knows JAVA herself, but that is another issue all in itself. I’ve been confused as to how methods and classes work. I’m creating this program that uses two files, one “main” file, and a “test” file. I can’t seem to get the “main” file correct, as the compiler keeps telling me that it cannot find the symbols, even though they are. In the “test” file, I can’t seem to get the compiler to recognize the methods from the “main” file. I have made sure that the files are in the same folder. I want to combine them into one file for simplicity, but I will lose points. I’ve included my code so far. I’m not looking for a “fix-it” solution, I just want to figure out why it’s not working. ANY help is appreciated, since my instructor isn’t of much assistance Thank you kindly!

MAIN FILE:

import java.util.Scanner;

class Fruit1 {
    static Scanner console = new Scanner(System.in);

    public static void main(String args[]) {

        String color;
        String taste;
    }

    public Fruit1() {
        // generic constructor

        color = "red";
        taste = "yum";

    }

    public Fruit1(String aColor, String aTaste) {
        // constructor with parameters
        color = aColor;
        taste = aTaste;
    }

    public Fruit1(String bColor, String bTaste) {

        color = bColor;
        taste = bTaste;
    }

    String getTaste() {
        return taste;
    }

    String getColor() {
        // Accessor method
        return color;
    }
}

TEST FILE:

import java.util.*;

public class Fruit1Test {

    static Scanner console = new Scanner(System.in);

    public static void main(String args[]){

        Fruit1 a = new Fruit1("pinkish-red", "sweet-tart");
        Fruit1 l = new Fruit1("yellow", "tart/sour");

        a.taste();
        a.color();
        l.taste();
        l.color();

        System.out.println("Your apple is " + a.color + "in color and has a " + a.taste + " taste. ");
        System.out.println("Your lemon is " + l.color + "in color and has a " + l.taste + " taste. ");
        System.out.println();
    }
}

Answer 1

a.taste(); will try to find method taste(); in your main file i.e. in Fruit1.java file. However as same is not found, it will throw error at compile time only that Method taste() is not found…

All below 4 statements will FAIL as those are not present…

a.taste();
a.color();
l.taste();
l.color();

As you are creating object of class by using below statement, already values to taste and color by use of constructor public Fruit1(String aColor, String aTaste){.

Fruit1 a = new Fruit1("pinkish-red", "sweet-tart");

I believe you now want to print the values of color and taste. To print those use getter methods that you have (getColor() & getTaste())

System.out.println("Your apple is " + a.getColor() + " in color and has a " + a.getTaste() + " taste. ");

System.out.println("Your Lemon is " + l.getColor() + " in color and has a " + l.getTaste() + " taste. ");

Note

You don’t need to write public Fruit1(String bColor, String bTaste){ again as you have already defined above that….

Also your below statement should be before constructor and out of psvm

String color;
String taste;

Let me know if you are unclear…

Good Luck
