How to remove comma from TextField in Java
I have a JFormattedTextField with the Name Hectare. The double type value is declared as shown below
String cultivationSize = JFormattedTextField3.getText();
double hectare = Double.parseDouble(cultivationSize);
Now the problem is that when i enter more than 3 digits, by default the comma is entered after 3 digits, e.g. 1,000. I have to add this value to some other value. But, due to this comma,I am unable to do it.
How can I remove comma and add this value to some开发者_开发技巧 other value?
Call the getValue() instead of getText()
on JFormattedTextField
A much easier solution
Format format = NumberFormat.getIntegerInstance();
format.setGroupingUsed(false);
JFormattedTextField jtf = new JFormattedTextField(format);
This will remove the grouping of the numbers using comma.
You should use MaskFormater like this:
zipField = new JFormattedTextField(
createFormatter("#####"));
...
protected MaskFormatter createFormatter(String s) {
MaskFormatter formatter = null;
try {
formatter = new MaskFormatter(s);
} catch (java.text.ParseException exc) {
System.err.println("formatter is bad: " + exc.getMessage());
System.exit(-1);
}
return formatter;
}
use string.replace(",","");
i.e. your code should look like -
double hectare = Double.parseDouble(cultivationSize.replaceAll(",",""));
