Java Scanner - hasNextShort() Method
The java.util.Scanner.hasNextShort() method returns true if the next token in the scanner's input can be interpreted as a short value in the default radix using the nextShort() method. The scanner does not advance past any input.
Syntax
public boolean hasNextShort()
Parameters
No parameter is required.
Return Value
Returns true if and only if the scanner's next token is a valid short value.
Exception
Throws IllegalStateException, if the scanner is closed.
Example:
In the example below, the java.util.Scanner.hasNextShort() method is used to check whether the scanner's next token is a valid short value or not.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//String to scan
String MyString = "Hello World 10 + 20 = 30.0";
//creating a Scanner
Scanner MyScan = new Scanner(MyString);
while(MyScan.hasNext()) {
//check if the next token is a short
//if yes, prints short value
if(MyScan.hasNextShort())
System.out.println("Short value is: "+ MyScan.nextShort());
//if the next token is not a short
else
System.out.println("No Short Value found: "+ MyScan.next());
}
//close the scanner
MyScan.close();
}
}
The output of the above code will be:
No Short Value found: Hello No Short Value found: World Short value is: 10 No Short Value found: + Short value is: 20 No Short Value found: = No Short Value found: 30.0
