Thread: JTextField (JDoubleField etc)

Hello,

I'm working with a project there ill need to enter some values for an Object and for this i'm using JTextField. However some of the variables are of the types double, int and bool. Is there a different method of reading thees types?

for example:

double playTime = this.playTime.getText();

This wont work because playTime is of type double and .getText(); takes a String.

How will i handle this? Id rather not convert from String to Double if its possible.

getText() returns a String, and there's no way around that. Converting the String to the actual data type is the only way. In a way, this gives the programmer maximum flexibility, allowing the user to put anything into a JTextField and the programmer the option to interpret the input as needed, generating an error if the input is invalid. Maximum flexibility can be a blessing and a curse.

Good luck!

I ended up going with this method:

double playTime = Double.parseDouble(this.title.getText());

I think this will work somewhat good tho ill need to cast some error statements in order for it to run safely.

Thanks for the input.

You could also use a JSpinner. These might be better suited when dealing with numbers as input.
