Java.util.Scanner.nextBigDecimal() Method
Description
The java.util.Scanner.nextBigDecimal() method scans the next token of the input as a BigDecimal. If the next token matches the Decimal regular expression defined above then the token is converted into a BigDecimal value as if by removing all group separators, mapping non-ASCII digits into ASCII digits via the Character.digit, and passing the resulting string to the BigDecimal(String) constructor.
Declaration
Following is the declaration for java.util.Scanner.nextBigDecimal() method
public BigDecimal nextBigDecimal()
Parameters
NA
Return Value
This method returns the BigDecimal scanned from the input
Exception
InputMismatchException − if the next token does not match the Decimal regular expression, or is out of range
NoSuchElementException − if the input is exhausted
IllegalStateException − if this scanner is closed
Example
The following example shows the usage of java.util.Scanner.nextBigDecimal() method.
package com.tutorialspoint; import java.util.*; public class ScannerDemo { public static void main(String[] args) { String s = "Hello World! 3 + 3.0 = 6 true"; // create a new scanner with the specified String Object Scanner scanner = new Scanner(s); // find the next BigDecimal token and print it // loop for the whole scanner while (scanner.hasNext()) { // if the next is BigDecimal, print found and the decimal if (scanner.hasNextBigDecimal()) { System.out.println("Found :" + scanner.nextBigDecimal()); } // if a BigDecimal is not found, print "Not Found" and the token System.out.println("Not Found :" + scanner.next()); } // close the scanner scanner.close(); } }
Let us compile and run the above program, this will produce the following result −
Not Found :Hello Not Found :World! Found :3 Not Found :+ Not Found :3.0 Not Found := Found :6 Not Found :true
