Java LocalDateTime isEqual()用法及代码示例


Java中的LocalDateTime类的isEqual()方法用于检查此日期是否等于指定的日期时间。

用法:

public boolean isEqual(ChronoLocalDateTime other)

参数:此方法接受参数other,该参数指定要与之进行比较的其他日期时间。它不能为空。


返回值:如果此日期时间等于指定的日期时间,则该函数返回布尔值。

以下示例程序旨在说明LocalDateTime.isEqual()方法:

示例1:

// Program to illustrate the isEqual() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Parses the date 
        LocalDateTime dt1 
            = LocalDateTime 
                  .parse("2018-11-03T12:45:30"); 
  
        // Prints the date 
        System.out.println("Date 1: " + dt1); 
  
        // Parses the date 
        LocalDateTime dt2 
            = LocalDateTime 
                  .parse("2018-11-03T12:45:30"); 
  
        // Prints the date 
        System.out.println("Date 2: " + dt2); 
  
        // Compares the date 
        System.out.println("After comparison: "
                           + dt2.isEqual(dt1)); 
    } 
}
输出:
Date 1: 2018-11-03T12:45:30
Date 2: 2018-11-03T12:45:30
After comparison: true

示例2:

// Program to illustrate the isEqual() method 
  
import java.util.*; 
import java.time.*; 
  
public class GfG { 
    public static void main(String[] args) 
    { 
        // Parses the date 
        LocalDateTime dt1 
            = LocalDateTime 
                  .parse("2010-12-05T12:50:30"); 
  
        // Prints the date 
        System.out.println("Date 1: " + dt1); 
  
        // Parses the date 
        LocalDateTime dt2 
            = LocalDateTime 
                  .parse("2012-05-10T12:50:30"); 
  
        // Prints the date 
        System.out.println("Date 2: " + dt2); 
  
        // Compares the date 
        System.out.println("After comparison: "
                           + dt2.isEqual(dt1)); 
    } 
}
输出:
Date 1: 2010-12-05T12:50:30
Date 2: 2012-05-10T12:50:30
After comparison: false
