Remember that a Java program must contain at least one class declaration (and the name of this class must match the program name case-sensitively), which inside must include the main-method with prescribed modifiers and signature. HINT: Draw up a table of your bank balance after 1 year, 2 years and so on: Year Balance ($)
0 10,000
1 10,000 + 0.05*(10,000)
2 Year 1 balance + 0.05*(Year 1 balance)
3 Year 2 balance + 0.05*(Year 2 balance)
... ... ...
You could write a program to print this output and then run it for, say, 10 years. You could then decide how you might write a program which will find out how many years you would need to accumulate $20,000. Note that you will need to use a loop to write this program. Because we may not have yet covered this in lectures, you may wish to wait a little, or learn it on your own (in the text book, or in the lecture slides, or in Java Tutorial, The while and do-while Statements). Assessment You will get up to two marks, if you present a solution to the Homework exercise during the next week lab.
