Answer / nageswararao
javac is an copiler it compiles the actual .java file into
byte code formate.
javax.swing,awt those are packages the basic difference is
awt using system graphical user interface but swing use it's
won graphical user interface.
public means u can access the anywhere outside the class also.
private mean u ca access the variable and methods inside the
class only.
protect variable can access sub class also but not other
than sub class.
static means it maintain one copy for all.that means any
object for particular class static variable will one to
all object of that class.
