Follow the Sun trail "Getting Started" to create and run a simple "Hello World!" program. You will need to subscribe to JDK-CURRENT. Nothing needs to be turned in for this part of the lab.
Find the on line API documentation for the standard Java
classes, version 5. Find the documentation for the Math
class inside the java.lang package. Copy the
description of the ceil method verbatim
into a text file called API.txt and include this text file
in your lab submission.
Modify the "Hello World!" program you wrote above to instead
print an element (any element) of the args[] array
which is passed in as a parameter to the main method.
By experimenting with this different command line
invocations of your program, surmise the relationship between
the contents of args[] and the command line.
That is, describe a precise rule for determining the
contents of args[].
Hint: try using a command line invocation like
java myHello some kind of arg
Submit your modified program (the java program only, not the
.class file). The program should include comments that reflect
your answer regarding the contents of args[].
