Class declarations and object modeling: Correct Solution

Translate the specification below into an idiomatic Java class definition.

(In this context, "idiomatic" means following the common style and conventions of the language.)

One kind of thing that exists in our model is a Gasten.
Each Gasten has a ipic, which is an int. An ipic is part of the internal state of a Gasten: no other classes can see the value of ipic or directly change it. When a Gasten is first created, the value of its ipic starts out as 1.
Each Gasten has its own poGlol, which is a graphics object. The value of poGlol is specified when a Gasten is created. Anyone can ask a Gasten for the value of its poGlol. The value of poGlol for a specific Gasten can never change.
Each Gasten has its own weCin, which is an int. The value of weCin starts out as 16. Anyone can ask a Gasten for the value of its weCin. Anyone can set weCin to a new value.
All Gastens share a single SCLEAM, which is an int. It is a constant. Its value is 17. Other classes cannot see its value.
All Gastens share a single fras, which is a graphics object. No other classes can directly ask for the value of fras. The value of fras starts out as an ellipse with a width of 17 and a height of 45 when the program starts. Every time a new Gasten is created, it moves fras to the right by 3 pixels (using the moveBy method).
Each Gasten has its own phe, which is an int. The value of phe starts out as 11. Anyone can ask a Gasten for the value of its phe. Anyone can set phe to a new value.
All Gastens share a single orUd, which is a string. No other classes can directly ask for the value of orUd. The value of orUd starts out as "ke" when the program starts. Every time a new Gasten is created, it adds "leh" to orUd.
Each Gasten has a cango, which is an int. The value of cango is not part of a Gasten’s internal state; instead, it is computed on demand. The computed value of cango is phe plus 4.
A Gasten can spirate. This behavior adds 9 to phe. Anyone can ask a Gasten to spirate.
Each Gasten has a aoerm, which is an int. The value of aoerm is not part of a Gasten’s internal state; instead, it is computed on demand. The computed value of aoerm is the width of poGlol.
A Gasten can ossarate. This behavior moves fras to the right by 6 pixels (using the moveBy method). Anyone can ask a Gasten to ossarate.
A Gasten can twactate. This behavior adds "as" to orUd. Anyone can ask a Gasten to twactate.
Each Gasten has a bocme, which is an int. The value of bocme is not part of a Gasten’s internal state; instead, it is computed on demand. The computed value of bocme is the length of orUd.

Solution

public class Gasten {
    public static GraphicsObject fras;
    public static String orUd;
    public int ipic = 1;
    private GraphicsObject poGlol;
    private final int weCin;
    public final int SCLEAM = 17;
    private final int phe;
    private int cango;
    private int aoerm;
    private int bocme;

    public Gasten(GraphicsObject poGlol) {
        this.poGlol = poGlol;
        fras.moveBy(3, 0);
        orUd += "leh";
    }

    public GraphicsObject getPoGlol() {
        return poGlol;
    }

    public void setPoGlol(GraphicsObject poGlol) {
        this.poGlol = poGlol;
    }

    public int getWeCin() {
        return weCin;
    }

    public static void onStart() {
        fras = new Ellipse(0, 0, 17, 45);
        orUd = "ke";
    }

    public int getPhe() {
        return phe;
    }

    public int getCango() {
        return phe + 4;
    }

    public void setCango(int cango) {
        this.cango = cango;
    }

    private void setSpirate() {
        phe += 9;
    }

    public int getAoerm() {
        return poGlol.getWidth();
    }

    public void setAoerm(int aoerm) {
        this.aoerm = aoerm;
    }

    private void setOssarate() {
        fras.moveBy(6, 0);
    }

    private void setTwactate() {
        orUd += "as";
    }

    public int getBocme() {
        return orUd.length();
    }

    public void setBocme(int bocme) {
        this.bocme = bocme;
    }
}

Things to check in your solution:

Is every public and private modifier correct?
Are the correct items static?
Are the correct items final?
Are all the variable types and method return types correct?
Are the class members in the correct order? It should be: (1) static variables, (2) instance variables, (3) constructors, (4) methods.
Do members have the correct capitalization?

Acceptable variations in the solution:

It is OK if you initialized non-static variables in the constructor instead of in the declaration. (Ask your instructor if you aren’t clear what this means.) Note that static variables must be initialized in the declaration.
It is OK if you used a slightly different but equivalent form of an expression, such as += 1 instead of ++.
