Java Scanner - hasNextBigDecimal() Method
The java.util.Scanner.hasNextBigDecimal() method returns true if the next token in the scanner's input can be interpreted as a BigDecimal value using the nextBigDecimal() method. The scanner does not advance past any input.
Syntax
public boolean hasNextBigDecimal()
Parameters
No parameter is required.
Return Value
Returns true if and only if the scanner's next token is a valid BigDecimal value.
Exception
Throws IllegalStateException, if the scanner is closed.
Example:
In the example below, the java.util.Scanner.hasNextBigDecimal() method is used to check whether the scanner's next token is a valid BigDecimal value or not.
import java.util.*;
public class MyClass {
public static void main(String[] args) {
//String to scan
String MyString = "Hello World 10 + 20 = 30.0";
//creating a Scanner
Scanner MyScan = new Scanner(MyString);
while(MyScan.hasNext()) {
//check if the next token is a BigDecimal
//if yes, prints BigDecimal value
if(MyScan.hasNextBigDecimal())
System.out.println("BigDecimal value is: "+ MyScan.nextBigDecimal());
//if the next token is not a BigDecimal
else
System.out.println("No BigDecimal Value found: "+ MyScan.next());
}
//close the scanner
MyScan.close();
}
}
The output of the above code will be:
No BigDecimal Value found: Hello No BigDecimal Value found: World BigDecimal value is: 10 No BigDecimal Value found: + BigDecimal value is: 20 No BigDecimal Value found: = BigDecimal value is: 30.0
