Q$4)$ Complete the following $($Java$)$ method to draw the following shape:

void draw $($int x$,$ int y$,$ int w$,$ int h$,$ Graphics g $)\{$

int x$1,$ x$2,$ x$3,$ y$1,$ y$2,$ r$,$ xLeft, yLeft; $//$ Calculation in terms of x $,$ y$,$ w$,$ h

g$.$drawRect$($x$-$w$,$ y$,$ w$,$ h$)$;

x$1=($int$)($Math$.$round$($ x$+\_\_\_\_\_\_\_\_\_\_))$ ;

x$2=\_\_\_\_\_\_\_\_$;

x$3=\_\_\_\_\_\_\_\_\_\_\_$;

y$1=\_\_\_\_\_\_\_\_\_\_$;

y$2=\_\_\_\_\_\_\_\_\_\_$ ;

r $=\_\_\_\_\_\_\_\_\_$;

xLeft$=\_\_\_\_\_\_\_\_\_$;

yLeft$=\_\_\_\_\_\_\_\_\_\_$ ;

g$.$drawLine$($ x$1,$ y$1,$ x$2,$ y$1)$;

g$.$drawLine$($ x$1,$ y$1,$ x$3,$ y$2)$;

g$.$drawLine$($ x$3,$ y$2,$ x$2,$ y$1)$;

g$.$drawOval$($ xLeft, yLeft, $2*$r $,2*$ r$)$;
