| 1. 7. 1. The Method main |
|
|
- A special method called main provides the entry point to an application.
- An application can have many classes and only one of the classes needs to have the method main.
- This method allows the class containing it to be invoked.
|
The signature of the method main is as follows. |
|
public class MainClass {
public static void main(String[] args) {
}
}
|
|
- In addition, you can pass arguments to main when using 'java' to run a class.
- To pass arguments, type them after the class name. Two arguments are separated by a space.
|
|
java className arg1 arg2 arg3 ...
|
|
All arguments must be passed as strings. For instance, to pass two arguments, "1" and "mode" when running the Test class, you type this: |
java Test 1 mode |
