Lady_Fox [76]

Answer:

Window.java

public class Window {
int width;
int height;
public Window(int width, int height){
this.width = width;
this.height = height;
}
public int getWidth(){
return width;
}
public int getHeight(){
return height;
}
public int getClientAreaHeight(){
return getHeight();
}
}

Main.java

public class Main {
public static void main (String [] args) {
Window win1 = new Window(12, 15);
System.out.println(win1.getClientAreaHeight());
}
}

Explanation:

Window.java

There is a Window class with two int type attributes, width and height (Line 1 - 3).

The constructor of this class will take two inputs, width and height and set these input to its attributes (Line 5 - 8). There are two methods getWidth and getHeight which will return the value of attributes width and height, respectively (Line 10 - 16).

The required new method getClientAreaHeight is defined in line 18 -20. This method will call the getHeight method to return the height value of the window (Line 19).

Main.java

We test the Window class by creating one Window instance and call the getClientAreaHeight method and print the return output (Line 1 -6).

We shall see 15 is printed.
