You should be defining your method outside of main, like:

public class YourClass
{
    public static void main(String... args)
    {

    }

    public char yourMethod()
    {
         //...
    }
}

Java does not support nested methods; however, there are workarounds, but they are not what you're looking for.

As for your question about args, it is simply an array of Strings that correspond to command line arguments. Consider the following:

public static void main(String... args) //alternative to String[] args
{
    for (String argument: args)
    {
        System.out.println(argument);
    }
}

Executing via java YourClass Hello, World!

Will print

Hello,
Word!
