embedded devices and mobile phones on the low

end, to enterprise servers and supercomputers on

the high end. Java is nearly everywhere in mobile

phones, Web servers and enterprise applications,

and while less common on desktop computers; Java

applets are often used to provide improved

functionality while browsing the World Wide Web.
