Help with a loop
I want to create a loop in my source, but I can't get it to work. What's
the problem?
This is my source:
Classfile: creates random digit between 1 and 10.
Sourcefile: must place two digits in two textFields. (digitField1 and
digitField2). I want the random created digits NOT to be the same, so I
want to let the program compare the two digits and IF they are the same,
than create a new random digit for digitField2. The program is must have
a loop to create a new random digit for digitField2 if digitField1 and
digitField2 have the same digit.
The problem is: I don't know how to create this loop. Can someone help
me?
This is the sourcefile (not the classfile):
DraaikubusRandom field1 = new DraaikubusRandom();
DraaikubusRandom field2 = new DraaikubusRandom();
void opnieuwButton_Action(java.awt.event.ActionEvent event)
{
//Creation random digit
//Digit 1
Digit1: //Label Digit1
field1.create();
digitField1.setText(String.valueOf(field1.getAmount()));
String correct1 = digitField1.getText();
int icorrect1 = Integer.parseInt(correct1);
//Digit 2
Digit2: //Label Digit2
field2.create(); //Create random digit
digitField2.setText(String.valueOf(field2.getAmount())); //Place
the random digit in digitField2
String correct2 = digitField2.getText();
int icorrect2 = Integer.parseInt(correct2); //Get the digit from
field2
if (icorrect1 == icorrect2) //Compare booth digits
{
continue Digit2; //If they are the same, I want the program to
create a new random digit and to do that it needs to go to the label for
Digit2.
}
else //If they are not the same, just continue.
{}
If someone could help me with this problem, because this doens't
work.The program says "no label defenition found for Digit2".
If you could correct my source, give me a new source or if you could
send me a default source for a loop, that would be great.
Thanks,
