The following code implements an equals method for the Triangle class. The Triangle class includes both a base and a height field of type double.

public $\_\_\_\_\_\_\_\_\_\_\_$ equals$($Object obj$)\{$

if $($obj $\_\_\_\_\_\_\_\_\_\_$ Triangle$)$

return this.base $==((\_\_\_\_\_\_\_\_\_)$ obj$).$base &&

this.height $==((\_\_\_\_\_\_\_\_\_)$ obj$).$height;

else

return $\_\_\_\_\_\_\_$;
