很抱歉再次编辑这篇文章，但我不想再发一篇文章，我想我会在这里问。
public static void main(String[] args)
{
// TODO code application logic here
char response = 0;
double grossAnnualIncome = 0.0;
double annualTuition = 0.0;
double annualCharity = 0.0;
double homeMortgage = 0.0;
double healthCredit = 0.0;
double annualAfterTaxes = 0.0;

System.out.printf( "Please enter your gross annual income or 0 for none: " );
grossAnnualIncome = input.nextDouble();
if( grossAnnualIncome > 0 )
{
System.out.printf( "Please enter your annual tuition and expenses for higher education or 0 for none: ");
annualTuition = input.nextDouble();
System.out.printf( "Please enter your annual charitable contributions or 0 for none: ");
annualCharity = input.nextDouble();
System.out.printf( "Please enter the annual interest paid for your home mortgage or 0 for none: ");
homeMortgage = input.nextDouble();
input.nextLine();
System.out.printf( "Did you purchase health insurance through your employer or outside the workplace?"

if( Character.toUpperCase(response) == 'Y' )
{
System.out.printf( "Are you filing as a family? Enter 'Y' or 'N': ");
response = input.nextLine().charAt(0);
if ( Character.toUpperCase(response) == 'Y' )
{
healthCredit = 3500;
}
else
{
if( Character.toUpperCase(response) == 'N' )
{
System.out.printf( "Are you filing as single? Enter 'Y' or 'N': ");

}
if( Character.toUpperCase(response) == 'Y')
{

}
}
}

}
taxableIncome = grossAnnualIncome - homeMortgage - annualTuition - annualCharity - healthCredit;
taxAt17 = taxableIncome * .17;
annualAfterTaxes = grossAnnualIncome - taxAt17;
monthlyAfterTaxes = annualAfterTaxes / 12;
ans1 = homeMortgage + annualTuition + annualCharity + healthCredit;
System.out.printf( "\nYOUR TAXES\n\n"
+ "Gross Annual Income: %,.0f\n\n"
+ "Deductions: \n"
+ "\tHigher Education: %,.0f\n"
+ "\tCharitable Contributions: %,.0f\n"

+ "Tax at 17%%: %,.0f\n"
+ "Annual Income After Taxes: %,.0f\n"
+ "Monthly Income After Taxes: %,.0f", grossAnnualIncome, annualTuition, annualCharity,
homeMortgage, healthCredit, taxAt17, annualAfterTaxes, monthlyAfterTaxes);
}
if( grossAnnualIncome <= 0 )
{
System.out.printf( "You earned no income so you owe no taxes!" );
}
System.exit(0);
}
}
我的两个输出都是正确的，但我的最后一个输出有问题。
我的最后一个输出需要阅读“你欠 0.00 美元的税款！”
当我编码时：
if (grossAnnualIncome <= ans1)
{
System.out.printf( "YOU OWE $0.00 IN TAXES!" );
}
它显示了从 GrossAnnualIncome > 0 输出的所有内容。
