java runtime environment running deadlock simulation. There are two additional process command files ("b0.dat" and "b1.dat") in the distribution. Run the deadlock simulator with this command:

1. java deadlock b 2 1 1, what happens? screenshot below

2. run java deadlock b 2 1 2 (screenshot below)

3. Why does the first command result in a deadlock but the second does not?

4. Explain your answer in terms of what is going on in the process command files, b0.dat and b1.dat
