Java Scanner hasNextShort() Method
Description
The java.util.Scanner.hasNextShort() method returns true if the next token in this 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.
Declaration
Following is the declaration for java.util.Scanner.hasNextShort() method
public boolean hasNextShort()
Parameters
NA
Return Value
This method returns true if and only if this scanner's next token is a valid short value in the default radix
Exception
IllegalStateException − if this scanner is closed
Java Scanner hasNextShort(int radix) Method
Description
The java.util.Scanner.hasNextShort(int radix) method returns true if the next token in this scanner's input can be interpreted as a short value in the specified radix using the nextShort() method. The scanner does not advance past any input.
Declaration
Following is the declaration for java.util.Scanner.hasNextShort() method
public boolean hasNextShort(int radix)
Parameters
radix − the radix used to interpret the token as a short value
Return Value
This method returns true if and only if this scanner's next token is a valid short value in the specified radix
Exception
IllegalStateException − if this scanner is closed
Checking Next Token as Short Using Scanner on a String Example
The following example shows the usage of Java Scanner hasNextShort() method to check if next token is a Short using a default radix. We've created a scanner object using a given string. Then we checked each token to be Short and printed. In the end scanner is closed using close() method.
package com.tutorialspoint; import java.util.Scanner; public class ScannerDemo { public static void main(String[] args) { String s = "Hello World! 3 + 3.0 = 6"; // create a new scanner with the specified String Object Scanner scanner = new Scanner(s); while (scanner.hasNext()) { // check if the scanner's next token is an Short System.out.println("" + scanner.hasNextShort()); // print what is scanned System.out.println("" + scanner.next()); } // close the scanner scanner.close(); } }
Output
Let us compile and run the above program, this will produce the following result −
false Hello false World! true 3 false + false 3.0 false = true 6
Checking Next Token as Short with Radix Using Scanner on a String Example
The following example shows the usage of Java Scanner hasNextShort() method to check if next token is a Short using a radix of 4. We've created a scanner object using a given string. Then we checked each token to be Short and printed. In the end scanner is closed using close() method.
package com.tutorialspoint; import java.util.Scanner; public class ScannerDemo { public static void main(String[] args) { String s = "Hello World! 3 + 3.0 = 6"; // create a new scanner with the specified String Object Scanner scanner = new Scanner(s); while (scanner.hasNext()) { // check if the scanner's next token is an Short System.out.println("" + scanner.hasNextShort(4)); // print what is scanned System.out.println("" + scanner.next()); } // close the scanner scanner.close(); } }
Output
Let us compile and run the above program, this will produce the following result −
false Hello false World! true 3 false + false 3.0 false = false 6
Checking Next Token as Short Using Scanner on User Input Example
The following example shows the usage of Java Scanner hasNextShort() method to check if next token is a Short. We've created a scanner object using System.in class. Then we checked each token to be Short and printed. In the end scanner is closed using close() method.
package com.tutorialspoint; import java.util.Scanner; public class ScannerDemo { public static void main(String[] args) { // create a new scanner with System Input Scanner scanner = new Scanner(System.in); // check if the scanner's next token is a Short if(scanner.hasNextShort()){ // print what is scanned System.out.println(scanner.next()); } else { scanner.next(); } // close the scanner scanner.close(); } }
Output
Let us compile and run the above program, this will produce the following result − (where we've entered 3.0.)
