every letter in a java keyword are uses as java identifiers.
an indentifer must be begin with a lower case letter , a dollar sign($),or an underscore(_);subsequent characters may be upper case letters, dollar signs, underscores
or digits.
Some Example are :
fobar      //legal
Myclass    //legal
$a         //legal
3_a        //illegal : starts with a digit
!thevalue  //illegal : bad 1st char
