Java中的 YearMonth compareTo() 方法
Java中 YearMonth 类的 compareTo() 方法用于比较两个 YearMonth 对象。它将这个 YearMonth 对象与作为参数传递给它的 YearMonth 对象进行比较。两个 YearMonth 实例之间的比较首先在 Year 的值上进行,然后在 Month 上进行。
语法:
public int compareTo(YearMonth otherYearMonth)
参数:此方法接受单个参数otherYearMonth ,它是要与此 YearMonth 进行比较的另一个 YearMonth 实例。
返回值:它根据比较返回一个整数比较器值:
- 如果此 YearMonth 大于 otherYearMonth,则返回 1。
- 如果此 YearMonth 小于 otherYearMonth,则返回 -1。
- 它返回 0 是这个 YearMonth 等于 otherYearMonth。
下面的程序说明了Java中 YearMonth 的 compareTo() 方法:
程序 1 :
Java
// Program to illustrate the compareTo() method
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Creates first YearMonth object
YearMonth firstYearMonth = YearMonth.of(2017, 8);
// Creates second YearMonth object
YearMonth secondYearMonth = YearMonth.of(2016, 11);
// compare the two YearMonth instances
System.out.println(firstYearMonth.compareTo(secondYearMonth));
}
}
Java
// Program to illustrate the compareTo() method
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Creates first YearMonth object
YearMonth firstYearMonth = YearMonth.of(2016, 11);
// Creates second YearMonth object
YearMonth secondYearMonth = YearMonth.of(2016, 11);
// compare the two YearMonth instances
System.out.println(firstYearMonth.compareTo(secondYearMonth));
}
}
输出:
1
方案二:
Java
// Program to illustrate the compareTo() method
import java.util.*;
import java.time.*;
public class GfG {
public static void main(String[] args)
{
// Creates first YearMonth object
YearMonth firstYearMonth = YearMonth.of(2016, 11);
// Creates second YearMonth object
YearMonth secondYearMonth = YearMonth.of(2016, 11);
// compare the two YearMonth instances
System.out.println(firstYearMonth.compareTo(secondYearMonth));
}
}
输出:
0
