Java
Java is a network-oriented programming language invented by Sun
Microsystems that is specifically designed for writing programs
that can be safely downloaded to your computer through the Internet
and immediately run without fear of viruses or other harm to your
computer or files. Using small Java programs (called " Applets
"), Web pages can include functions such as animations, calculators,
and other fancy tricks.
JavaScript
JavaScript is a programming language that is mostly used in web
pages, usually to add features that make the web page more interactive.
When JavaScript is included in an HTML file it relies upon the browser
to interpret the JavaScript. When JavaScript is combined with Cascading
Style Sheets (CSS), and later versions of HTML (4.0 and later) the
result is often called DHTML. JavaScript was invented by Netscape
and was going to be called "LiveScript", but the name
was changed to JavaScript to cash in on the popularity of Java .
JavaScript and Java are two different programming languages.
