Java Double Parse Error: '3,000.00' - How to Fix

This error occurs because the string '3,000.00' contains a comma (,) as a thousand separator, which is not valid in a Double value. A Double value should only contain digits and a dot (.) as a decimal separator. To fix this error, you can remove the comma from the string before converting it to a Double value. For example:

String str = '3,000.00';
str = str.replace(',', ''); // remove comma
Double value = Double.parseDouble(str);
