what is meaning of public static void main in java?
and what the difference between public and private?
|
|
|
|
|
|
The JVM is the key player here... it is going to execute your program... so public static void main is like an accessibility option for the JVM...
public ==> so that the jvm can access your program/class from any where (since it is public as the name suggests)... change it to private and your program wont work... because the jvm cannot access private stuff... and if the jvm cant access the class/program it cant execute it
static ==> so that the jvm does not need to create an object for your class to run your program
void ==> your main function is not going to return any value to the jvm
main ==> this is like the cue music to the jvm... this is the stating point of your program... this is the function that your jvm calls so as to execute your program

That means you are expected to write it, as it is your assignment. If you have specific questions then ask them, but do not expect people here to write the entire assignment for you.

Hello everyone,
Is it possible to serialize null as just null in java?
For example, if I have a row such as below,
Col1 Col2 Col3
---- ---- ----
A null B
Is it possible to seriazle the row above to the json below?
{"Col1":"A", "Col2":null, "Col3":"B"}
Thanks for taking your time and help a lot.
Best regards,
Zaw Min Tun

In fact, I'm doing this in Java, it's a Maven project and hosted as a web service on GlassFish. The service returns the data in json format. The problem is when the values are null, I have to serialize them as "" or "null". I want to return as just null. However, I still can't find a way.

Thanks a lot for this useful information.

Just noting that I do JSON all the time and I definitely do not program in javascript. I use it in Java and C#.

Thanks for the information. About the only thing I know about it is what JSON actually stands for, which, according to http://json.org/[^], is JavaScript Object Notation.

I am a third year computer science student and have a project to build. I am to build a restaurant reservation system, considering most activities about a restaurant. I can only do basic java. Any ideas on how to implement this idea?

You really need to have a good understanding of the use of classes and their methods and properties for such a project. However, the first thing you need to do is work on the actual design of your project. The data store, what information you need to keep, and how you will access it. The inputs, how customers will request reservations. The outputs, how information will be displayed etc. All of that needs to be designed before you can start writing any code.
