Create a UML diagram based on the Java code linked to later on this page.

There are two Java interfaces.

These must be "abstract classes" in UML notation $($e$.$g$.,,$ the class names need to be italicized$).$

ASIDE: If italics is not available or if hand$-$drawn then one must used the $"\{$abstract$\}"$ classifier which must appear below the name of the class$/$interface that is abstract$.$

One of the Java interfaces is a generic interface so such must be shown as parameterized type.

All public, protected, and private methods must be properly indicated.

There are three Java classes.

All public, protected, and private properties and methods must be properly indicated.

With all of code, involved types must be indicated.

In UML types are always the name followed by a colon followed by the type.

e$.$g$.,$ "alpha : int" $($without the quotes$)$ would be a variable of type int called alpha

e$.$g$.,$ "foo$($a : int, b : float$)$ : string" would be a function called foo having two parameters a and b where a is an int, b is a float, and the function returns a string

the Java code is below:

GenericPoint$2$D$.$java

interface GenericPoint$2$D

$\{$

public E getX$()$;

public E getY$()$;

$\}$

GPoint$2$D$.$java

class GPoint$2$D implements GenericPoint$2$D

$\{$

private E x;

private E y;

public E getX$()\{$ return x; $\}$

public E getY$()\{$ return y; $\}$

protected void setXY$($E x$,$ E y$)$

$\{$

x $=$ x;

y $=$ y;

$\}$

$\}$

Point$2$D$.$java

class Point$2$D extends Point$2$DBase implements Point$2$DInterface

$\{$

private boolean flag;

public double getX$()$

$\{$

return super.x;

$\}$

public double getY$()$

$\{$

return super.y;

$\}$

protected void setXY$($double x$,$ double y$)$

$\{$

super.x $=$ x;

super.y $=$ y;

$\}$

$\}$

Point$2$DBase.java

class Point$2$DBase

$\{$

protected double x;

protected double y;

$\}$

Point$2$DInterface.java

interface Point$2$DInterface

$\{$

public double getX$()$;

public double getY$()$;

$\}$
