Task

Assessment 1 has total 10 marks. Marks will be scaled according to the value of the assignment. There are two tasks in assessment 1, Task1: display a pattern and Task 2: calculate entry charges of a Zoo. 

Task 1

Value: 3 marks

Write a Java program that displays the following pattern (i..e, I LOVE U):

Hint: You may need to use the System.out.println() function. Use one vertical space between two letters in a word and two vertical spaces between two words (i.e., I, LOVE, and U).

Task 2

Value: 7 marks

Problem Description:

The Australian Government introduces a new personal income tax in 2016. The personal income tax is calculated based on filing status and taxable income. There are four filing statuses: single filers, married filing jointly, married filing separately, and head of household. The tax rates vary every year. The following table shows the rates for 2016. If you are, say, single with a taxable income of $10,000, the first $8,350 is taxed at 10% and the other $1,650 is taxed at 15%. So, your tax is $1,082.5.

You need to write a program to compute the personal income tax. Your program should prompt the user to enter the filing status and taxable income and compute the tax. Enter 0 for single filers, 1 for married filing jointly, 2 for married filing separately, and 3 for head of household.

Here are sample runs of the program:

Sample 1:

Enter the filing status: 0

Enter the taxable income: 100000

Tax is 21720.0

Sample 2:

Enter the filing status: 1

Enter the taxable income: 300339

Tax is 76932.87

Sample 3:

Enter the filing status: 2

Enter the taxable income: 123500

Tax is 29665.5

Sample 4:

Enter the filing status: 3

Enter the taxable income: 4545402

Tax is 1565250.7
