JAC444 Workshop 11 Comparable Interface and Cloneable Interface solved

Description

Description: The tasks in this workshop is a recap of some concepts from previous workshops and some new concepts like Comparable Interface and Cloneable Interface. Task 1: Define a class named Time for encapsulating a time. The class contains the following: 1. A data field of the long time that stores the elapsed time since midnight, Jan 1, 1970. 2. A no-arg constructor that constructs a Time for the current time. 3. A constructor with the specified hour, minute, and second to create a Time. 4. A constructor with the specified elapsed time since midnight, Jan 1, 1970. 5. The getHour() method that returns the current hour in the range 0-23. 6. The getMinute() method that returns the current minute in the range 0-59. 7. The getSecond() method that returns the current second in the range 0-59. 8. The getSeconds() method that returns the elapsed total seconds. 9. The toString() method that returns a string such as “1 hour 2 minutes 1 second” and “14 hours 21 minutes 1 second”. 10. Implement the Comparable interface to compare this Time with another one based on their elapse seconds. The compareTo method returns the difference between this object’s elapse seconds and the another’s. 11. Implement the Cloneable interface to clone a Time object. Write a test program that produces the following sample run: Sample Run – 1 Enter time1 (hour minute second): 331 34 674 19 hours 45 minutes 14 seconds Elapsed seconds in time1: 1194314 JAC – 444 Semester —- Enter time2 (elapsed time in seconds): 93889345 16 hours 22 minutes 25 seconds Elapsed seconds in time2: 93889345 time1.compareTo(time2)? -92695031 time3 is created as a clone of time1 time1.compareTo(time3)? 0 End Sample Run – 1 Sample Run – 2 Enter time1 (hour minute second): 1 2 3 1 hour 2 minutes 3 seconds Elapsed seconds in time1: 3723 Enter time2 (elapsed time in seconds): 193032 5 hours 37 minutes 12 seconds Elapsed seconds in time2: 193032 time1.compareTo(time2)? -189309 time3 is created as a clone of time1 time1.compareTo(time3)? 0 End Sample Run – 2 Task 2: Write a simulation of Banks. Banks trade to other bank by lending and borrowing the money to each other. In tough economic times, if a bank goes bankrupt, it may not be able to pay back the loan. JAC – 444 Semester —- A bank’s total assets are its current balance plus its loans to other banks. • The diagram below shows five different banks (0 to 4). • The banks’ current balances are 25, 125, 175, 75, and 181 million dollars, respectively. • The directed edge from node 1 to node 2 indicates that bank 1 lends 40 million dollars to bank 2. Banks lend money to each other • If a bank’s total assets are under a certain limit, the bank is unsafe. • The money it borrowed cannot be returned to the lender, and the lender cannot count the loan in its total assets. • Consequently, the lender may also be unsafe, if its total assets are under the limit. Write a program to find all the unsafe banks. Your program reads the input as follows. 1. It first reads two integers n and limit, a. n indicates the number of banks b. limit is the minimum total assets for keeping a bank safe from the user. 2. It then reads n lines that describe the information for n banks with IDs from 0 to n-1. 3. The first number in the line is the bank’s balance, the second number indicates the number of banks that borrowed money from the bank, and the rest are pairs of two numbers. 4. Each pair describes a borrower. The first number in the pair is the borrower’s ID and the second is the amount borrowed. For example, the input for the five banks in above picture is as follows (note that the limit is 201): Current balance Bank ID Lending money JAC – 444 Semester —- Number of banks: 5 Minimum asset limit: 201 For Bank # 0 Balance: 25 Number of banks Loaned: 2 Bank ID who gets the loan: 1 Loaned Amount: 100.5 Bank ID who gets the loan: 4 Loaned Amount: 320.5 For Bank # 1 Balance: 125 Number of banks Loaned: 2 Bank ID who gets the loan: 2 Loaned Amount: 40 Bank ID who gets the loan: 3 Loaned Amount: 85 For Bank # 2 Balance: 175 Number of banks Loaned: 2 Bank ID who gets the loan: 0 Loaned Amount: 125 Bank ID who gets the loan: 3 Loaned Amount: 75 For Bank # 3 Balance: 75 Number of banks Loaned: 1 Bank ID who gets the loan: 0 Loaned Amount: 125 For Bank # 4 Balance: 181 Number of banks Loaned: 1 Bank ID who gets the loan: 2 Loaned Amount: 125 The total assets of bank 3 are (75 + 125), which is under 201, so bank 3 is unsafe. After bank 3 becomes unsafe, the total assets of bank 1 fall below (125 + 40). Thus, bank 1 is also unsafe. Note: Program should take inputs from the user like Number of banks, Minimum asset limit and then all other inputs JAC – 444 Semester —- The output of the program should be Unsafe banks are Bank 3 and Bank 1 Bank 3 got bankrupted and it got the loan from Bank 1, because Bank 3 is unsafe due to under the limit Bank 1 is also unsafe due to lower limit.
