To perform arithmetic operations on java.time.LocalDate objects, you can use the plus() and minus() methods with a java.time.Period object. A Period object represents a specific number of days, months, and years.

Here’s an example:

import java.time.LocalDate;
import java.time.Period;

public class Main {
    public static void main(String[] args) {
        LocalDate date = LocalDate.now();
        System.out.println("Current date: " + date);

        // Add 1 day, 2 months, and 3 years to the current date
        LocalDate future = date.plus(Period.of(3, 2, 1));
        System.out.println("Future date: " + future);

        // Subtract 5 days, 4 months, and 2 years from the current date
        LocalDate past = date.minus(Period.of(2, 4, 5));
        System.out.println("Past date: " + past);
    }
}

You can also use the plusDays(), plusMonths(), and plusYears() methods to add or subtract specific numbers of days, months, or years:

import java.time.LocalDate;

public class Main {
    public static void main(String[] args) {
        LocalDate date = LocalDate.now();
        System.out.println("Current date: " + date);

        // Add 100 days to the current date
        LocalDate future = date.plusDays(100);
        System.out.println("Future date: " + future);

        // Subtract 1 month and 3 years from the current date
        LocalDate past = date.minusMonths(1).minusYears(3);
        System.out.println("Past date: " + past);
    }
}
