Java Scanner nextShort() Method
Example
Print the value of every short integer in the string:
// Create a scanner object
Scanner myObj = new Scanner("An short is a number between -32,768 and 32,767");
// Print the value of every short in the scanner
while (myObj.hasNext()) {
if (myObj.hasNextShort()) {
System.out.println(myObj.nextShort());
} else {
myObj.next();
}
}
Definition and Usage
The nextShort() method returns the short value of the number that the next token represents. The token must represent a 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 the useLocale() method.
If the radix 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 the radix parameter is not used then it interprets numbers using the scanner's radix which is 10 by default, but it can be changed with the useRadix() 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 the useDelimiter() method.
