返回值:该方法返回一个基于该时间的本地时间,并加上分钟。
下面的程序说明了 plusMinutes()方法:
程序 1:
// Java program to demonstrate
// LocalTime.plusMinutes() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime object
LocalTime time
= LocalTime.parse("19:34:50.63");
// print LocalTime
System.out.println("LocalTime before addition: "
+ time);
// add 55 Minutes using plusMinutes()
LocalTime value = time.plusMinutes(55);
// print result
System.out.println("LocalTime after addition: "
+ value);
}
}
输出:
LocalTime before addition: 19:34:50.630
LocalTime after addition: 20:29:50.630
程序二:
// Java program to demonstrate
// LocalTime.plusMinutes() method
import java.time.*;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime object
LocalTime time
= LocalTime.parse("01:00:01");
// print LocalTime
System.out.println("LocalTime before addition: "
+ time);
// add -600 Minutes using plusMinutes()
LocalTime value = time.plusMinutes(-600);
// print result
System.out.println("LocalTime after addition: "
+ value);
}
}
输出:
LocalTime before addition: 01:00:01
LocalTime after addition: 15:00:01
