hai in our program we include java.awt.* package to use the components.
if we import this package,all the properties can used to our
program.then why
we import the java.awt.event.*?(when we use the java.awt package the
event class proprties also imported(?)

Packages are not hierarchical.

/import java.awt.*/ only imports all the classes in /java.awt/, not the
packages. So /java.awt.client.*/ classes are not imported unless you also
import that package explicitly.
