Hi Friend,

Differences:

1) Java is a Object Oriented programming language developed by Sun Microsystems, while JavaScript is a scripting language that was introduced by Netscape.
2) Java creates applications that run in a virtual machine while javaScript code is run on a browser only.
3) Java code needs to be compiled while JavaScript code are all in text.
4) Java can only be used as a back-end language within a web environment while Javascript is used for front-end web development.
5) Java follows strong type checking where as Javascript

is very flexible in datatype(loosly typed).
Ex : Variables in Java:
int num;String st;
Variables in Javascript:
var name;
6) Java support function declarations, with access specifiers,parameter datatype,return type while Javascript does not.
Ex: function declaration in java:
public int functionName(int no){
}
function declaration in javascript:
function fcnName(str){
}

Core Java" is basically the language, coupled with the standard core API that comes with any Java distribution.
