Knowledge on getting inputs and printing outputs using Scanner.
Description:
For your second homework assignment you are required to write two separate Java programs,
TipCalculator.java and
TenseCorrector.java, that will prompt users to provide certain information which the program will process and produce an output according to its functions respectively.
Task 1: Tip Calculator
Task 2: Tense Corrector
Task 1: Tip Calculator
This program uses the Scanner class to prompt users for an amount to be paid by the user in US dollars (a double) and the percentage of tip the user is willing to give (an int). The base amount (a double), tip amount alone (a double), and the total amount to be paid (a double) should then be produced as an output on the console as shown on the example below. It is important to follow the format closely.
Example/Demonstration:
Price($): 200
Tip Percentage(%): 15
Price Without Tip($): 200.00
Tip Amount($): 30.00
Total Amount($): 230.00
Task 2: Tense Corrector
This program uses the Scanner class to prompt users for a sentence with possible grammatical errors in it (a String). The program will then manipulate the given string by replacing all the words in the table below into their past tense. You will only be checked for the successful conversion of these given words. The “corrected” sentence (a String) will then be displayed on the console in the next line as shown below.
