Core java - Interview Questions and Answers for 'Ibm pune' - 1 question(s) found - Order By Newest

Frequently asked to fresh graduates and less experienced.
 Q1. Why do we write public static void main ? Can we use some other syntax too for main ?Core Java
Admin

Ans.
1. public is the access modifier that makes the method accessible from anywhere, static is the keyword that makes it accessible even without creating any object and using class name only , void means it doesnt return anything , String args[] is the array of argument that this method receives.

2. If I use Main , it will compile correctly as Java will treat it as just another method but it wont be the method "main" which Java looks for when it looks to execute the class and hence will throw

Error: Main method not found in class , please define the main method as:
public static void main(String[] args)

3. Main is not a keyword but a special string that Java looks for while initiating the main thread.
