多选题 Given the design implied by this partially implemented class:
2. public class RobotDog {
3. int size;
4. void bark() { /* do barking */ }
5. int getSize() {return size; }
6. {size = 16; }
7. int getNetworkPrinterID() {
8. /* do lookup */
9. return 37;
10. }
11. voidprintRobotDogStuff(intprinterID) { /*print RobotDog stuff*/ }
12. }
Which are true? (Choose all that apply.)

A、 Compilation fails.
B、 To improve cohesion, the size variable should be declared private.
C、 To improve cohesion, the initialization block should be placed inside a constructor.
D、 To improve cohesion, printRobotDogStuff() should be moved to a different class.
E、 To improve cohesion, getNetworkPrinterlD0 should be moved to a different class.
