Java.util.Scanner.hasNextByte() Method
Description
The java.util.Scanner.hasNextByte(int radix) method returns true if the next token in this scanner's input can be interpreted as a byte value in the specified radix using the nextByte() method. The scanner does not advance past any input.
Declaration
Following is the declaration for java.util.Scanner.hasNextByte() method
public boolean hasNextByte(int radix)
Parameters
radix − the radix used to interpret the token as a byte value
Return Value
This method returns true if and only if this scanner's next token is a valid byte value
Exception
IllegalStateException − if this scanner is closed
Example
The following example shows the usage of java.util.Scanner.hasNextByte() method.
package com.tutorialspoint; import java.util.*; 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 a byte with radix 4 System.out.println("" + scanner.hasNextByte(4)); // print what is scanned System.out.println("" + scanner.next()); } // close the scanner scanner.close(); } }
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
