Hello I am having errors when I compile, I left my code below

Using as reference the design model below, write the java code for the implementation of the classes

public class Point2D { // - denotes private, + denotes public access // these variables are private and cannot be accessed outside of this class

private float x, y, point ;

// default constructor with no arguments, sets value public Point2D() { this.x = 0.0f; this.y = 0.0f;

}

// 2nd constructors

public Point2D(float x, float y) { this.x = x ; this.y = y ; }

// getX

public float getX() { return this.x; }

// setX

public void setX(float x) { this.x = x; }

// getY public float getY() { return this.y; }

// setY public void setY(float y) { this.y = y; }

// setXY with x and y lol

public void setXY(float x, float y) { this.x = x; this.y = y; }

// getXY return 2 element in int array containing x and y

public float[] getXY() { float[] result = new float[2]; result[0] = this.x; result[1] = this.y;

return result;

}

// Return "(x,y)" public String toString() { return "(" + this.x + "," + this.y + ")"; } }

//Point3D class

public class Point3D extends Point2D

{

Private float z;

public Point3D(float x, float y, float z)

{

super(x,y);

this.z = z;

}

public Point3D()

{

super();

this.z = 0.0f;

}

public float getZ()

{

return this.z;

}

public void setZ(float z)

{

this.z = z;

}

public void setXYZ(float x, float y, float z)

{

super(x,y);

}

public String toString()

{

return "(" + super.getX() + "," + super.getY() + "," + this.z + ")";

}

}
