下面是说明equals()方法的示例：示例1：

Java

// 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
            // JapaneseDate Object
            JapaneseDate hidate1
              = JapaneseDate.now();
 
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate2 
              = JapaneseDate.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

范例2：

Java

// 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
            // JapaneseDate Object
            JapaneseDate hidate1 
              = JapaneseDate.now();
 
            // creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate2 
              = JapaneseDate.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
