Java 中的计时 toString()方法，示例

原文:https://www . geesforgeks . org/chronoperiod-tostring-method-in-Java-with-examples/

Java 中计时周期接口的 toString() 方法用来返回这个计时周期的字符串表示。

语法:

ChronoPeriod toString()

参数:该方法不接受任何参数。

返回值:这个方法返回这个的字符串表示

下面的程序说明了上面的方法:

程序 1 :

// Java code to show the toString() function

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printString(ChronoPeriod p1)
    {

        System.out.println(p1.toString());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = 4;
        int months = 11;
        int days = 10;
        ChronoPeriod p1 = Period.of(year, months, days);

        printString(p1);
    }
}

输出:

P4Y11M10D

程序二 :

// Java code to show the toString() function

import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;

public class ChronoPeriodClass {

    // Function to negate given periods
    static void printString(ChronoPeriod p1)
    {

        System.out.println(p1.toString());
    }

    // Driver Code
    public static void main(String[] args)
    {
        // Defining period
        int year = -4;
        int months = -11;
        int days = -10;
        ChronoPeriod p1 = Period.of(year, months, days);

        printString(p1);
    }
}

输出:

P-4Y-11M-10D
