1. Variable names are case-sensitive.
2. A variable’s name can be any legal identifier.
3. It can contain Unicode letter,Digits and Two Special Characters such as Underscore and dollar Sign.
4. Length of Variable name can be any number.
5. Its necessary to use Alphabet at the start (however we can use underscore , but do not use it )
6. Some auto generated variables may contain ‘$‘ sign. But try to avoid using Dollar Sign.
7. White space is not permitted.
8. Special Characters are not allowed.
9. Digit at start is not allowed.
10. Subsequent characters may be letters, digits, dollar signs, or underscore characters.
11. Variable name must not be a keyword or reserved word.

1. Java was designed by Sun Microsystems in the early 1990s.
2. Basic aim of java was to solve the problem of connecting many household machines together.
3. Project was unsuccessful because no one wanted to use it.
4. Earlier Name of Java : OAK
5. Creator of Java :  James Gosling  (the father of Java)
6. As there was another language called Oak , they decided to rename OAK. New name was given to OAK , OAK was renamed Java in 1994
7. Java was publicly released on : May 27, 1995
8. Java was targeted at :  Internet development
9. Applets Had early support from companies : Netscape Communications

Language was created with 5 main goals:

1. It should be object oriented
2. A single representation of a program could be executed on multiple operating systems
3. It should fully support network programming
4. It should execute code from remote sources securely
5. It should be easy to use
