Answer:
The GUI component is defined as follows
abstract interface GUIComponent {
public abstract void onClick(int a);
public abstract void onCursorFocus(int a);
public abstract boolean move(int a, int b);
public abstract boolean move(Position a);
public abstract boolean move(Dimension a);
public abstract boolean resize(int a, int b);
}
Explanation:
Here the first line is the definition of the interface GUIComponent with the type abstract.
The second line is the public abstract with no return onClick function for int a.
The third line is the public abstract with no return onClickFocus function for int a.
The fourth line is the public abstract with boolean return moving the cursor to int a and int b.
The fifth line is the public abstract with boolean return moving the cursor to Position a.
The sixth line is the public abstract with boolean return dimensioning the cursor to Position a.
The seventh line is the public abstract with boolean return resizing to int a and int b.
