Answer:
A Java application always contains a single method called the "main" method. This method serves as the starting point of the application and is the first method that is executed when the program is run. The signature of the main method is as follows:
public static void main(String[] args)
The keyword "public" specifies that the main method is accessible from anywhere in the program. The keyword "static" means that the method can be called without creating an instance of the class that contains the main method. The keyword "void" indicates that the method does not return any value. The parameter "String[] args" is an array of strings that can be passed to the main method when the program is run.
