Java ScannerhasNextShort() Method
Example
Print the value of every short integer in the string:
// Create a scanner objectScanner myObj = new Scanner("An short is a number between -32,768 and 32,767");// Print the value of every short in the scannerwhile (myObj.hasNext()) { if (myObj.hasNextShort()) { System.out.println(myObj.nextShort()); } else { myObj.next(); }}Definition and Usage
ThehasNextShort() method returnstrue if the next token represents a number that can be stored by theshort data type, which is any whole number between -32,768 and 32,767.
The scanner is able to interpret digit groupings, such as using a comma for separating groups of 3 digits. The format of the groupings depends on the locale settings of the scanner, which can be changed with theuseLocale() method.
If theradix parameter is used, then it interprets numbers using the radix. For example, a radix of 16 would interpret numbers as hexadecimal (digits 0 to 9 and A to F). If theradix parameter is not used then it interprets numbers using the scanner's radix, which is 10 by default but it can be changed with theuseRadix() method.
What is a token?
A token is a sequence of characters separated from other tokens by delimiters. The default delimiter is a block of whitespace characters but it can be changed with theuseDelimiter() method.
