Simple java tax program with incorrect output
I have a java program that is outputting the wrong numbers. What did I do wrong?
Here are numbers the program should output:
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
Here is the code:
public void theProgram() {
int choice;
int income;
Scanner input = new Scanner(System.in);
System.out.println("Personal Income Tax Calculator ");
System.out.println("Filing status options: ");
System.out.println(" 0 - Single");
System.out
.println(" 1 - Married Filing Jointly or Qualified Widow(er)");
System.out.println(" 2 - Married Filing Seperately");
System.out.println(" 3 - Head of Household");
System.out.println("To quit enter 4. ");
System.out.print("Enter your filing status: ");
choice = input.nextInt();
if (choice >= 0 && choice <= 3) {
System.out.print("Enter the taxable income: ");
income = input.nextInt();
while (income < 0) {
System.out.println("Error: Please enter a positive number.");
System.out.print("Enter the taxable income: ");
income = input.nextInt();
}

Explanation / Answer
Here is the working code of the above program please post entire list of interest values for the range of amounts as we cannot extract the values from the program i guess the percentage values which you are using might not be the correct values.so please check the percentage values
