The program is a GUI program. It is a windowed program with a calculate button that calculates sales tax. Here is the section of code that I beleive has to be modified. The Variables A3 and A4 must put out in currency with two decimal places.


public void actionPerformed(ActionEvent e)
{
double A1, A2, A3, A4;


A1 = Double.parseDouble(TF1.getText());
A2 = Double.parseDouble(TF2.getText());
A3 = (A1 * A2);
A4 = (A1 + A3);

TF3.setText("$" + A3);
TF4.setText("$" + A4);
}
}

Try changing the following line:

A3 = (A1 * A2);

to:

A3 = Math.round(100 * A1 * A2)/100;
