Java中的 LocalDateTime isEqual() 方法及示例
Java中LocalDateTime 类的isEqual()方法用于检查该日期是否等于指定的日期时间。
句法:
public boolean isEqual(ChronoLocalDateTime other)
参数:此方法接受参数other指定要比较的其他日期时间。它不应该为空。
返回:如果此日期时间等于指定的日期时间,则函数返回布尔值。
下面的程序说明了 LocalDateTime.isEqual() 方法:
方案一:
// 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
方案二:
// 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
