Convert $16500.00 String to 16500 Integer

Question

Im having an issue trying to convert $16500.00 String to 16500 Integer.

This is what i have at the moment but its failing with:

FATAL EXCEPTION: main java.lang.NumberFormatException: Invalid int: "[]"

The code i have is:

String depTest = mDepositAmount.getText().toString();
String deptest2 = Arrays.toString(depTest.replace("R", "").replace(",", "").split("."));
int dep = Integer.parseInt(deptest2);

Please could you help me with getting the end result to 16500. I know how to convert it to int by using Integer.parseInt its just im struggling to get the end result to be 16500 in String

`Arrays.toString` is not what you want... This turns an array containing for example 1 and 2 to the String `[1, 2]`. — Tunaki, Mar 09 '16 at 10:30

Does your original string always starts with character '$' and followed by number format?
If so try this one:

String org = "$16500.00";
String numbersOnly = org.substring(1);   // "16500.00"
int yourInteger = (int)(Float.parseFloat(numbersOnly));

// if you need String, convert it to String again
String integerString = Integer.toString(yourInteger);

whilst this method will work, there's no validation on the first character so 12345.67 will be parsed as 2345.67. IMHO a DecimalFormat is better – lance-java Mar 09 '16 at 10:57

You can try with this

String getValue = "$16500.00";
String removeFirstCharecter = getValue.substring(1);   // "16500.00"
String [] getString = removeFirstCharecter.split("\\.");

String firstIntValue = (getString[0]); //16500
String sirstIntValue = (getString[1]); //00

Now you can convert firstIntValue String to Integer .

String getRequiredValue = Integer.toString(firstIntValue); //16500

This is great because it then shows me how to use the .split method! Up voted for it! – Stillie Mar 09 '16 at 10:47

You could use a DecimalFormat

import java.text.*;

NumberFormat nf = new DecimalFormat("$0.00");
int value = (int) nf.parse("$16500.00");

It may be happen because of $ sign so, Just take one another Text view only for Price 16500 and other for $ sign. then convert the Integer.parseInt(textview.getText().toString);

yea sorry, i dont know why i used the $ in the question! blonde moment, it was mean to be R. Removing the relevant text is fine, its removing the .00 that i am having an issue – Stillie Mar 09 '16 at 10:34
