protected voiddoClass(java.lang.String className)

			System.out.println(Modifier.toString(c.getModifiers()) + ' " + c + " {");

			int mods;

public static voidmain(java.lang.String[] argv)
Simple main program, construct self, process each class name found in argv.

		MyJavaP pp = new MyJavaP();

			System.err.println("Usage: MyJavaP className [...]");
			System.exit(1);
		} else for (int i=0; i<argv.length; i++)
