Scanner Class reset() method

• reset() method is available in java.util package.
• reset() method is used to reset this Scanner object and it resets a scanner skips all its explicit state information which may have been changed by calling useDelimiter() and useLocale() and useRadix().
• reset() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• reset() method does not throw an exception at the time of reset this Scanner.

Syntax:

    public Scanner reset();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is Scanner, it returns a "Scanner" object.

Example:

// Java program to demonstrate the example 
// of Scanner reset() method of Scanner 

import java.util.*;

public class ResetOfScanner {
    public static void main(String[] args) {
        String str = "Hi, true \n IncludeHelp! 8 + 2.0f = 10.0f";

        // Instantiate Scanner with the 
        // given str
        Scanner sc = new Scanner(str);

        // Display Scanner
        System.out.println("sc.nextLine(): " + sc.nextLine());

        // set radix by using useRadix() method
        sc.useRadix(20);

        // By using reset() method is to reset
        // this Scanner 
        sc.reset();

        // Here, we are checking the dafault radix
        // which is reset by using reset() method
        System.out.println("sc.radix(): " + sc.radix());

        // close the scanner
        sc.close();
    }
}

Output

sc.nextLine(): Hi, true 
sc.radix(): 10
