11. The code shown in Figure 3, can deadlock if bidirectional transfers happen at the same time, i.e. transfer from tank A to tank B happens at the same time (concurrent) that there is another transfer from tank B to tank A. [7 points] a. Explain why it will deadlock. [2 points] b. Rewrite the method transfer To so that it will not deadlock. [4 points] c. Explain why your solution in 11 b. is deadlock free. [1 point] public final class Water Tank { .. private int water TankId; // Unique Identifier public synchronized void fillTank(int noliters) {...} public synchronized void drainTank(int noliters) {...} public synchronized void transferTo(int noliters, Water Tank wtRight) { this.drainTank(noLiters); wtRight.fillTank(noLiters); } } Figure 3: WaterTank Class
