Result is: 1111111110

Example 2

import java.util.*;
public class ScannerNextBigDecimalExample2 {  
    public static void main(String args[]){   	
    	  String str1 = "JavaTpoint.com";  	
        Scanner scanner = new Scanner(str1); 
        System.out.println("Result: "+scanner.nextBigDecimal());
        System.out.println("String Value: "+scanner.next());         
        scanner.close();
	  }  
}

Example 3

import java.util.*;
public class ScannerNextBigDecimalExample3 {  
    public static void main(String args[]){   	
    	   String str = "Google.com 111 + 11111 = 11222.0  true";
         Scanner scanner = new Scanner(str);
         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());
         }
         scanner.close();
	   }  
}

Output:

Not Found :Google.com
Found :111
