ValueRange isValidValue() method in Java with Examples

The isValidValue() method of ValueRange class is used to check if the value which is passed as parameter is within the valid range. This method validates that the value is within the stored range of values.

Syntax:

public boolean isValidValue(long value)

Parameters: This method accepts value which is the value to check.

Return value: This method returns true if the value is valid.

Below programs illustrate the ValueRange.isValidValue() method:
Program 1:

// Java program to demonstrate
// ValueRange.isValidValue() method

import java.time.LocalDateTime;
import java.time.temporal.ChronoField;
import java.time.temporal.ValueRange;

public class GFG {
    public static void main(String[] args)
    {

        // create LocalDateTime
        LocalDateTime l1
            = LocalDateTime
                  .parse("2020-10-06T08:21:14");

        // Get ValueRange object
        ValueRange vR
            = l1.range(ChronoField.DAY_OF_MONTH);

        // apply isValidValue()
        boolean response = vR.isValidValue(12);

        // print results
        System.out.println("isValidValue: "
                           + response);
    }
}

Output:

isValidValue: true

Program 2:

// Java program to demonstrate
// ValueRange.isValidValue() method

import java.time.temporal.ValueRange;

public class GFG {
    public static void main(String[] args)
    {

        // create ValueRange object
        ValueRange vRange = ValueRange.of(1111, 66666);

        // apply isValidValue()
        boolean response = vRange.isValidValue(12);

        // print results
        System.out.println("isValidValue: "
                           + response);
    }
}

Output:

isValidValue: false
