    Default Compiling Error on Print method

    I'm creating a program as an exersize which is supposed to take command-line arguments and print out their values.

    Here is my code:

    class InputDataTypes {
    	public static void main(String args[]);
    		Boolean a = Boolean.valueOf(args[0]);
    		Character b = Character.valueOf(args[1]);
    		Byte c = Byte.valueOf(args[2]);
    		Short d = Short.valueOf(args[3]);
    		Integer e = Integer.valueOf(args[4]);
    		Long f = Long.valueOf(args[5]);
    		Float g = Float.valueOf(args[6]);
    		Double h = Double.valueOf(args[7]);
    		System.out.println(a);
    		System.out.println(b);
    		System.out.println(c);
    	}
    }

    These are the error messages I'm receiving:

    InputDataTypes.java:11: error: <identifier> expected
    System.out.println(a);
    ^
    InputDataTypes.java:11: error: <identifier> expected
    System.out.println(a);
    ^
    InputDataTypes.java:12: error: <identifier> expected
    System.out.println(b);
    ^
    InputDataTypes.java:12: error: <identifier> expected
    System.out.println(b);
    ^
    InputDataTypes.java:13: error: <identifier> expected
    System.out.println(c);
    ^
    InputDataTypes.java:13: error: <identifier> expected
    System.out.println(c);
    ^
    InputDataTypes.java:15: error: class, interface, or enum expected

    Every single print method is giving an error. I'm not sure why this is happening.

    You need to use {}s with a method to enclose all the statements that are in the method.

    All the statements before the print statements are valid outside of a method.
    The print statements must be defined inside of a method.
    If you don't understand my answer, don't ignore it, ask a question.

    Ah I can't believe I forgot to put the opening bracket after the main method. That's what I get for code late at night.
