website templates
This is the line of code that actually web template
does all the work. In this case, I'm using some of the
code that the programmers at Sun have already created
to display the text "Hello from Java!". In
free
web templates particular, I'm using the java.lang
package's System class here. website templates Libraries
of classes are called packages in Java, and the javaJang
package is built into every Java program web site template
which means you don't have to take special steps , to
make use of it, as you do with other Java packages.
The java.lang package's System class includes a data
member named out, which is an object itself and . has
a method free website templates named println that does
the actual displaying of text. free web templates Note
also that this line of code ends with a semicolon. To
translate a Java program into a bytecode file, you use
the Java compiler called javac
(on Windows machines, this program is calledjavac.exe
and is located in the bin subdirectory). Here's how
you use javac in general: "Hm," says the novice
programmer, "I've got a problem
docile templates
This end-of-staiement convention
is something that Java has inherited website templates
from C and C++ (in fact, it inherited a lot from C and
C++). You end nearly all statements in Java with a .
semicolon. Although JavaScript, as implemented in the
major browsers, lets you drop the semicolons at the
end of each statement, Java insists that they web site
template be there, so we can't skip them here. You've
created your new application web template and stored
it in a file named app Java. What's the next step? How
do you get it to actually run? Take a look at the next
section. The big boss, while chomping on a cigar and
standing right behind you as you enter your new Java
application into a file says, "Hm" clearly
not impressed, "what's next?" "Now,"
you say, free web templates "I have to compile
the program free
website templates and then I can run it."
"OK," the big boss says, "amaze me."
fr-iwi.That's because the Date
class is part of the Java util package, and you havefree
website templates import that package before you can
use it." The NP asks, "Import it?" The
classes that Sun has created for you to use are stored
in class libraries called packages
