I want to ask. I have 3 textfield. For example I just have 2 number so I fill at the first and second textField. But, if I want to calculate the value of this textfield, I need to enter 0 to the third textfield. So, I want to ask about that and I used JAVA GUI ECLIPSE

When you get the value from the 3rd text field you could check if it's empty and treat that as a zero, eg something like

int value3;
if (field3.getText().trim().length() > 0) value3 = Integer.parseInt(field3.getText());
else value3 = 0;
