When a BGP router is not capable of understanding 4-byte AS numbers, it will see 4-byte AS numbers as a special, reserved, 2-byte AS number in the AS path. Which 2-byte AS number is this reserved one?()
1. class A { 2. public byte getNumber () { 3. return 1; 4. } 5. } 6. 7. class B extends A { 8. public short getNumber() { 9. return 2; 10. } 11. 12. public static void main (String args[]) { 13. B b = new B (); 14. System.out.printIn(b.getNumber()) 15. } 16. } What is the result?()
字节,记为Byte或大写B,这是计算机的最小存储单位。
class A { public byte getNumber() { return 1; } } class B extends A { public short getNumber() { return 2; } public static void main(String args[]) { B b = new B(); System.out.println(b.getNumber()); } } What is the result?()
