Java 中的 ZoneOffsetTransition equals()方法，示例

原文:https://www . geeksforgeeks . org/zoneoffsettransition-equals-method-in-Java-with-example/

Java . time . ZoneOffsetTransition类的 equals() 方法用于对 ZoneOffsetTransition 类型的两个对象进行比较。

语法:

public boolean equals(Object other)

参数:该方法以其他 zoneoffsetTransition 的对象为参数。

返回值:如果两个对象相等，该方法返回真，否则返回假。

以下是说明等于()方法的示例:

例 1:

// Java program to demonstrate
// equals() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;

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

        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25, 03,
                24, 45, 0);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(8);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans2
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // comparing both object using
        // equals() method
        boolean status
            = zonetrans1.equals(zonetrans2);

        // display the result
        if (status)
            System.out.println(
                "zonetrans1 is equal to zonetrans2");
        else
            System.out.println(
                "zonetrans1 is not equal to zonetrans2");
    }
}

输出:

zonetrans1 is equal to zonetrans2

例 2:

// Java program to demonstrate
// equals() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;

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

        // creating and initializing
        // the object of LocalDateTime
        LocalDateTime loc
            = LocalDateTime.of(
                1999, 04, 25,
                03, 24, 45, 0);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off1
            = ZoneOffset.ofTotalSeconds(8);

        // creating and initializing
        // the object of ZoneOffset
        ZoneOffset off2
            = ZoneOffset.ofTotalSeconds(12);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans1
            = ZoneOffsetTransition.of(
                loc, off1, off2);

        // creating and initializing
        // ZoneOffsetTransition Object
        ZoneOffsetTransition zonetrans2
            = ZoneOffsetTransition
                  .of(LocalDateTime.of(
                          1999, 04, 25, 03,
                          24, 48, 0),
                      off1, off2);

        // comparing both object using
        // equals() method
        boolean status
            = zonetrans1.equals(zonetrans2);

        // display the result
        if (status)
            System.out.println(
                "zonetrans1 is equal to zonetrans2");
        else
            System.out.println(
                "zonetrans1 is not equal to zonetrans2");
    }
}

输出:

zonetrans1 is not equal to zonetrans2
