Solved Splitting int from currency on sign

Right so I basically want to charge a player the amount that is displayed on the sign. How would I do this? The sign reads £x (x being any value given). How would I seperate the currency sign from the integer then change the String (which is what the value is) into an integer? I've tried parsing the int but it comes back as a numberformatexception.

This is what the sign looks like:

Code:

 
event.setLine(2, ChatColor.GOLD + "Price " + ChatColor.GRAY + ": " + ChatColor.GREEN + "£" + ChatColor.GREEN + event.getLine(2));

 

I'm probably being really stupid, this is what I've done and it still isn't working.

Code:

String line2 = s.getLine(2);
String[] line_2 = line2.split("\\£");
String line = line_2[1];
double line1 = Double.parseDouble(line);

 

@NullPointerExptn This worked for me:

Code:Java

 
if (sign.getLine(2).contains("£")) {
    try {
        String getAmount = sign.getLine(2).substring(1);
        Integer.parseInt(getAmount);
        Integer amount = Integer.valueOf(getAmount);
        //Remove amount
    } catch (NumberFormatException e) {
        //Send some message?
    }
}
 

You can just edit some stuff in this to make it work for you, hope this helps.

 

I put this here:

Code:

if (s.getLine(1).equalsIgnoreCase(ChatColor.GOLD + "Tier " + ChatColor.GRAY + ": " + ChatColor.GREEN + "1")) {

if (s.getLine(2).contains("£")) {
try {
String getAmount = ChatColor.stripColor(s.getLine(2).substring(1));
Integer.parseInt(getAmount)
;Integer amount =Integer.valueOf(getAmount);
e.getPlayer().sendMessage("TEST " + amount);
} catch (NumberFormatException exptn) {
exptn.printStackTrace();}
}

But it throws this:

Code:

java.lang.NumberFormatException: For input string: "aú1"
[18:52:51 WARN]:  at java.lang.NumberFormatException.forInputString(Unknown Source)
[18:52:51 WARN]:  at java.lang.Integer.parseInt(Unknown Source)

[18:52:51 WARN]:  at me.admin.rentahorse.listeners.SignClick.onSignClick(SignClick.java:44)

This is line 44

Code:

Integer.parseInt(getAmount);

 

@NullPointerExptn What does line 3 look like? (line 2 in code)

 

This is the sign. I've tried splitting it on the £, it doesn't work
