Help for java homework

Hi, I'm having a little problem doing my homework which is due in less than 24 hours. XD

Here are the attributes (please pay attention to the constant values which are the types of wine):

Java Code

private String name;
private int type;
private String origin;
private double cost;

final static int red = 1, white = 2, pink = 3;

Method toString

Java Code

public String toString(){
    	return "\n\t" + getName() + " is a " + getType() + " wine from " + getOrigin() + " and it costs " + getCost() + "$.";

My problem: I need to create a private method to get the type of wine as a string. toString will be using this private method. Can anyone please help me? Thank you in advance!

can you please elaborate more of what do you need in your program?

Sounds to me like you want to put all your toString code into a private method, then just call the private method from toString().

Or even better, instead of having static ints represent the type of wine, use an enum

Java Code

    public enum WineType {
        RED,
        WHITE,
        PINK;
    }

However if I read this question correct you want some help on implementing the getTypeAsString method I take it.

Java Code

private String getTypeAsString() {
    if type equals 1 return "red";
    else if type equals 2 return "white";
    else if type equals 3 return "pink";
    else return "unknown";
}

You have to figure out how to write the code for the actual thing but that's more or less what you can do. You can of course use a switch as well.

I don't like java... C programming was much easier for me. XD

So I did a switch...

Java Code

	final static int red = 1;
	final static int white = 2;
	final static int pink = 3;

	private String getTypeAsString() {
            switch(type){
    	         case red: return "red";
    				break;
    	        case white: return "white";
    				   break;
    	        case pink: return "pink";
    				 break;
	    }
	}

Method toString

Java Code

public String toString(){
    	return "\n\t" + getName() + " is a " + getType(getTypeAsString()) + " wine from " + getOrigin() + " and it costs " + getCost() + "$.";

JCreator LE is telling me getType() cannot be applied to java.lang.string -_- The switch would have worked in C programming...

Its probably because you're trying to pass the value of getTypeAsString into the getType method in your toString method.
