Correct way to approach INR currency in Java

I've this code for INR 

long tenderedAmt = (long) NumberFormat.getNumberInstance(new Locale("en", "in")).parse(jAmtTenderedFormattedTextField.getText());`

But when I enter amount 00.50 that throwing exception 

java.lang.ClassCastException: java.lang.Double cannot be cast to java.lang.Long

Using Double

Double tenderedAmt = (Double) NumberFormat.getNumberInstance(new Locale("en", "in")).parse(jAmtTenderedFormattedTextField.getText());

This snippet throws same exception.

Using 

Double tenderedAmt = (Double) jAmtTenderedFormattedTextField.getText());

In above snippet if I've entered 1000.00 it suppose 1.00 instead thousand.
And throwing
java.lang.NumberFormatException: For input string: "1,000.00"
So how can I have approach currency in correct way?

Here's the javadoc of parse method and this is what it says:

Parses text from the beginning of the given string to produce a number. The method may not use the entire text of the given string.

So, if we assign the result to Number type, it should give us the correct value, e.g.:

Number result = NumberFormat.getNumberInstance(new Locale("en", "in")).parse("1000.00");
System.out.println(result.doubleValue());

This should print 1000.0 as expected. Also, we don't need to cast this into any type. We can simply call doubleValue() or longValue() or any other xxxValue() to get the corresponding type.

If it prints 1.0 then I would recommend checking the value returned by jAmtTenderedFormattedTextField.getText().
