Given: 1. public class Test { 2. public static void main(String [] args) { 3. System.out.println(args.length > 4 && 4. args[4].equals(-d)); 5. } 6. } If the program is invoked using the command line: java Test One Two Three -d What is the result? true false compilation fails An exception is thrown at runtime. 22. Given: 1. public class X { 2. private static int a; 3. public static void main(String [] args) { 4. modify(a); 5.
