Well i will not provide u the basics of Java coz we all are smart programmers, I will touch areas which are essential for programming but at the same time we don't have sufficient resources to get solution.
My First topic will be to create a jar File
How to create a Jar file? ( very common question )
Well many of us use IDEs (Netbeans or eclipse) to create jar files which is the easiest method.
But there are various tricks in which we have to create jar files manually ( these tricks will be provided in future posts NOT TO WORRY :) ) & for starters this is the best place to learn to create jar files using cmd/terminal
Steps are as follows
1. Make a folder and in that folder compile your .java files. [let the folder location be C:/../Desktop/x]
2. Now after successful compiling the .java files open your notepad and type in it
Main-Class: <your .java file name which u want to run when you run jar file> <Note:press enter after this line>
[optional] Class-Path: <if you are using any library write them here and separate file name with space> <Note:press enter after this line>
Eg: Suppose my main java file name is “main.java” and i am using three libraries “c.jar lib/a.jar lib/b.jar” . So my notepad will contain
Main-Class: main <Note:press enter after this line>
Class-Path: lib/a.jar lib/b.jar c.jar <Note:press enter after this line>
Save as the file “main.mf” at the location “C:/../Desktop/x/main.mf”
3. Now open your cmd/terminal and type in it cd C:/../Desktop/x press enter
4. Now type the command “jar cvfm <your jar file name>.jar main.mf *.class” and press enter
5. Thats it in 4 steps you created your jar file congrats to all :)
Thats it for this post
Enjoy
