    Default Re: Please answer this questions?

    Why not answer the question by writing a test program to print out the default value? Or...another way, do an internet search? One of the top hits for the keywords in your post, one which contains the answer:
    Primitive Data Types (The Java™ Tutorials > Learning the Java Language > Language Basics)
    Sorry to be blunt, but either way it's problem solving - a rather important trait in the world of programming.

    		System.out.println("byte default value: " + dtd.byteValue);
    		System.out.println("short default value: " + dtd.shortValue);
    		System.out.println("int default value: " + dtd.intValue);
    		System.out.println("long default value: " + dtd.longValue);
    		System.out.println("float default value: " + dtd.floatValue);
    		System.out.println("double default value: " + dtd.doubleValue);
    		System.out.println("char default value: " + dtd.charValue);
    		System.out.println("boolean default value: " + dtd.booleanValue);
    		System.out.println("String default value: " + dtd.stringValue);
