Java中的 MonthDay isBefore() 方法及示例
MonthDay类的isBefore()方法用于检查此 MonthDay 是否在作为参数传递的 MonthDay 之前。此方法返回一个布尔值,显示相同。
句法:
public boolean isBefore(MonthDay other)
参数:此方法接受一个参数, other是要比较的另一个月份。
返回值:如果此 MonthDay 在指定的 MonthDay 之前,此方法返回 true,否则返回 false。
下面的程序说明了 isBefore() 方法:
方案一:
// Java program to demonstrate
// MonthDay.isBefore() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a MonthDay object
MonthDay month = MonthDay.parse("--10-12");
// create other MonthDay object
MonthDay othermonth = MonthDay.parse("--11-12");
// apply isBefore() method
boolean value = month.isBefore(othermonth);
// print instance
System.out.println("monthday:"
+ month + " is before monthday:"
+ othermonth + " = "
+ value);
}
}
输出:
monthday:--10-12 is before monthday:--11-12 = true
方案二:
// Java program to demonstrate
// MonthDay.isBefore() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a MonthDay object
MonthDay month = MonthDay.parse("--10-12");
// create other MonthDay object
MonthDay othermonth = MonthDay.parse("--09-12");
// apply isBefore() method
boolean value = month.isBefore(othermonth);
// print instance
System.out.println("monthday:"
+ month + " is before monthday:"
+ othermonth + " = "
+ value);
}
}
输出:
monthday:--10-12 is before monthday:--09-12 = false
