Java中的 MinguoDate equals() 方法及示例

Java.time.chrono.MinguoDate类的equals()方法用于比较这个民国日期和另一个民国日期。

句法:

public boolean equals(Object obj)

参数:此方法以等效对象作为参数与此民国数据进行比较。

返回值:如果两个日期相等,则此方法返回true ,否则返回false

以下是说明equals()方法的示例:
示例 1:

// Java program to demonstrate
// equals() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate1
                = MinguoDate.now();
  
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate2
                = MinguoDate.now();
  
            // comparing both date
            // by using equals() method
            boolean status
                = hidate1.equals(hidate2);
  
            // display the result
            if (status)
                System.out.println(
                    "both dates are equal");
            else
                System.out.println(
                    "both dates are not equal");
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}
输出:
both dates are equal

示例 2:

// Java program to demonstrate
// equals() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate1
                = MinguoDate.now();
  
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate2
                = MinguoDate.of(2008, 03, 23);
  
            // comparing both date
            // by using equals() method
            boolean status
                = hidate1.equals(hidate2);
  
            // display the result
            if (status)
                System.out.println(
                    "both dates are equal");
            else
                System.out.println(
                    "both dates are not equal");
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can"
                + " not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}
输出:
both dates are not equal
