The method name "equals" suggests that it is used for object comparison. The parameter is of type Stock which means it accepts a Stock object argument. The return type of the method is boolean, which implies that the method returns true or false to indicate whether the two Stock objects are equal or not. The fact that it is not specified as private implies that it is a public method accessible from other classes.
