Coding issue

[EnchantBook]

Spoiler: IsInt

private boolean isInt(String string) {
try {
Integer.parseInt(string);
return true;
} catch(NumberFormatException nfe) {
return false;
}

}

Spoiler: If Statement

if(material == null || !isInt(rawAmount)){
player.sendMessage(ChatColor.RED + "Invalid use!");
player.sendMessage(ChatColor.RED + rawAmount);
player.sendMessage(isInt(rawMaterial) + "");
return true;
}

For some reason this returns a false even if It's an integer

Use StringUtils#isNumeric.

 

[EnchantBook]

Use StringUtils#isNumeric.

Could you use that in the context of the code above? very new to this
and if so, how?

On a quick glance I believe your code should work.

I know this works, but it is the same thing basically.

Spoiler: Code

try{
int i = Integer.parseInt(args[0]);
//Whatever
}catch(Exception e) {
//Exception
}

Not sure what the issue is exactly, might be with the checks.

You could try changing it to any of these.

if(isInt(rawAmount) == false) {}
if(!(isInt(rawAmount))) {}
if(isInt(rawAmount) != true) {}
if(isInt(raw)){}else{//whatever}

StringUtils#isNumeric Checks if a CharSequence contains only Unicode digits. You will just have to remove "!isInt(rawAmount)" and put "!StringUtils.isNumeric(rawAmount)"

My code is working for a friend but not for me, can't find the reason why though[DOUBLEPOST=1533776024][/DOUBLEPOST]

Made that work but still having the original issue for some reason

 

[Irantwomiles]

Explain what you're trying to achieve, there might be a better way of doing it.

 

[devo]

NumberUtils.isDigits(12)

I'm checking if an argument isn't an integer

 

[WulfGamesYT]

Try the following:

public boolean isNumeric(Object object) { return object.toString().matches("^[0-9]\\d*$"); }

then simply use:

if(!isNumeric(54)) { /* not a number */ }

 

[devo]

Literally don't listen to all of these people. Your isInt method works fine. Paste how you get your rawMaterial and rawAmount variables

if it worked fine he wouldn't be making this thread

 

[EnchantBook]

That's true, but I use the same method and haven't had any issues with it.
However, there could be an issue with whatever he's inputting into it.
Such as "24 " is not an Integer

Sent the code to a friend and it worked fine for him, something with the compiling most likely, Thanks though
