Scanner Class nextBigDecimal() method

• nextBigDecimal() method is available in java.util package.
• nextBigDecimal() method is used to get the big decimal scanned from the input.
• nextBigDecimal() 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.
• nextBigDecimal() method may throw an exception at the time of returning BigDecimal.
  • InputMismatchException: This exception may throw when the next token input mismatch or not.
  • NoSuchElementException: This exception may throw when no such element exists.
  • IllegalStateException: This exception may throw when this Scanner is not opened.

Syntax:

    public BigDecimal nextBigDecimal();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is BigDecimal, it returns the BigDecimal scanned from the input.

Example:

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

import java.util.*;

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

        // Instantiates a Scanner object with
        // the given string str
        Scanner sc = new Scanner(str);

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

        // By using nextBigDecimal() method is
        // to return the BigDecimal if exists
        System.out.println("sc.nextBigDecimal(): " + sc.nextBigDecimal());

        // By using close() method is to 
        // close the Scanner object
        sc.close();
    }
}

Output

sc.nextLine(): Hi, [IncludeHelp] +
sc.nextBigDecimal(): 10.0
