ChronoLocalDate minus(TemporalAmount) method in Java with Examples

minus(TemporalAmount) method of a ChronoLocalDate interface used to returns a copy of this ChronoLocalDate with the specified amount subtracted to ChronoLocalDate.The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
Syntax:

public ChronoLocalDate minus(TemporalAmount amountTosubtract)

Parameters: This method accepts one single parameter amountTosubtract which is the amount to subtract, It should not be null.
Return value: This method returns ChronoLocalDate based on this date-time with the subtraction made, not null.
Exception: This method throws following Exceptions: 

• DateTimeException: if the subtraction cannot be made
• ArithmeticException: if numeric overflow occurs

Below programs illustrate the minus() method:
Program 1:

Java

// Java program to demonstrate
// ChronoLocalDate.minus() method

import java.time.*;
import java.time.chrono.*;

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

        // create a ChronoLocalDate object
        ChronoLocalDate zonedlt
            = LocalDate.parse("2018-12-06");

        // subtract 30 Days to ChronoLocalDate
        ChronoLocalDate value
            = zonedlt.minus(Period.ofDays(30));

        // print result
        System.out.println("ChronoLocalDate after"
                           + " subtracting Days: "
                           + value);
    }
}

Output:

ChronoLocalDate after subtracting Days: 2018-11-06
