Java日历时间，分钟是错误的 [英] Java calendar time, minute is wrong

问题描述

有人知道为什么 java.util.Caldendar 中的 MINUTE 方法返回错误的分钟吗?

Anyone know why the MINUTE method in java.util.Caldendar returns an incorrect minute?

import java.util.Calendar;

public class Clock
{
    // Instance fields
    private Calendar time;

    /**
     * Constructor. Starts the clock at the current operating system time
     */
    public Clock()
    {
       System.out.println(this.time.HOUR_OF_DAY+":"+this.time.MINUTE);
    }
}

推荐答案

Calendar.MINUTE 不是实际的分钟，而是传递到get()"以获取值的常量索引值.例如:

Calendar.MINUTE isn't the actual minute but rather a constant index value to pass into "get()" in order to get the value. For example:

System.out.println(this.time.get(Calendar.HOUR_OF_DAY) + ":" + this.time.get(Calendar.MINUTE));
