What happens when you don't return anything?

you use void when you don't expect any value to be returned from that method. for example int height = calculateHeight (); then you expect the method will return integer value. But if you want your method only to do something then you can use void

we can use void so that there is no need of return to be used....but once you r using int we need to return the value otherwise garbage value
