Java split string is only keeping one character after split

Question

I've a simple code:

System.out.println("Enter ItemID ~SPACE~ Quantity: ");
String itemInfo = scanner.next();

String[] selectedItem = itemInfo.split("\\s+",2);

System.out.println(selectedItem.length);
System.out.println("The item selected for order is: " + selectedItem[0] + " and the quantity is: " + selectedItem[1]);

Let's say user enters 4 6 then the print statements prints 1 and then an error about Exception in thread "main" java.lang which basically means selectedItem[1] does not exist or is null.

My question is how do I split the string so that when user enters 4 6 it give me 4 and 6 on indexes 0 and 1?

Using scanner.next() already "splits" around spaces. Scanner.next() only reads the next token, where tokens are separated by the scanner's separator which by default includes spaces. Maybe you wanted to use scanner.nextLine() ? — Aaron

Your code is fine with String itemInfo = "4 6"; The problem is from your scanner has shown by @Aaron. — Pilpo

Either use Scanner#nextLine() to read the whole line and then split the tokens, or read each token via next() like you do, then there is no need to split by space. — maloomeister

you have to just change scanner.next() to scanner.nextLine() and it will be done.
