Write a java program to calculate the net income for a person by using three methods. Ask the user for the gross income amount using JOptionPane. It will then call the method (pg 272) to calculate and print the net income. Method 1: Write a void method (pg 271) to calculate net income that receives the income amount. Call the find tax method (pg 272), passing the income amount to the find tax rate (pg 279). Use the rate to calculate the tax amount. Then call the net income print method passing income and tax amount (pg 282). Method 2: Write a value-returning method (pg 293) that finds the tax percentage using the brackets below (similar to Java 2, but its goal is only the find and return the rate). 0.00 - 40,000.01 Over 40,000.00 10% 100,000.00 15% 100,000.00 20% Method 3: Write a void method that receives the income amount and the tax amount, then display the income, tax amount, and net income (gross minus taxes) using JOptionPane. Example for input of $75,000: Income Amount: $75,000 $11, 250 $63,750 Tax Amount: Net Income: Hints/Tips: • It took me a little over 20 minutes to complete. • Remember that Java doesn't store percentages, it stores numbers. If you use 15 for the percentage, you must divide it by 100 to get .15. In your case, you can pass back .15 for 15% • You can use escape sequence characters (pg 37) in JoptionPane and you can use String.format() like printf (pg 172). • You can calculate the net income in the JOptionPane but you must put the equation in parenthesis, or you can calculate it into another field and print that field. main method - get gross income amount, call method to calc net income calc net income method - receiving inc amt, call method to find tax rate by passing inc amt.
