Conditional logic

[blknav01]

Greetings all. I am having a problem with getting java program to produce the correct output. I am being asked to use conditional logic to determine a tax rate category. I am not getting any syntax errors at all but I am not getting the correct code after putting in the annual salary as directed.
Here is my code. Any help in pointing me in the right direction will be greatly appreciated.


import javax.swing.JOptionPane;

public class TaxCodeTest1 {
public static void main(String[] args) {


float salary = 0;
float code = 0;

JOptionPane.showInputDialog(null,
"Enter annual salary, example 10000",
"Input",
JOptionPane.QUESTION_MESSAGE);



if (salary < 15000) { //Salary less than 15000 code 1
code = '1';
JOptionPane.showMessageDialog(null, " Tax Code =" + 1);
}
else if (salary >= 15001 - 25000) { //salary between 15001 - 25000 code 2
code = '2';
JOptionPane.showMessageDialog(null, " Tax Code =" + 2);
}
else if (salary >= 25001 - 40000) { //salary between 25001 - 40000 code 3
code = '3';
}
else if (salary >= 40001 - 65000) { //salary between 40001 - 65000
code = '4';
}
else if (salary >= 65001 - 80000) { //salary between 65001 - 80000
code = '5';
}
else if (salary > 80000) { //salary greater than 80000
code = '6';


JOptionPane.showMessageDialog(null, "The code based on annual salary") ;

}
}
}

You can't test whether or not a value lies in an interval that way: the '-' symbol
actually means subtraction so the compiler (that doesn't know what you want to
do) compiles your code but your compiled code does quite something different
from what you want to accomplish.

If you want to check whether or not a value 'v' lies in an interval 'lo' ... 'hi' do this:

if (lo <= v && v < hi) ...
 

The interval is 'half open' i.e. the interval is [lo, hi)

kind regards,

1) Use code tags when posting code.
2.) Your salary is always 0. You did not assign the value entered to the salary variable.

Hey, haven't we seen this code before?

As in "been there; done that"? ;-)
