Question

我不确定我究竟做错了什么，但我想将get方法中的变量放入testClass中的print statetment。例如，用户输入所有信息，然后输出语句。

import java.util.Calendar;
import java.util.Scanner;
import java.text.DateFormat;
import java.text.SimpleDateFormat;

public class testClass {

public testClass() {
    System.out.println("ALARM SET TO: " + getHour ":" + getMinutes + amOrPm);

}

public int getHour() {
    Scanner input = new Scanner(System.in);
    int getHour;
    System.out.println("ENTER HOUR FOR YOUR ALARM: ");
    getHour = input.nextInt();
    return getHour; 
}

public int getMinutes() {
    Scanner input = new Scanner(System.in);
    int getMinutes;
    System.out.println("ENTER MINUTES FOR YOUR ALARM: ");
    getMinutes = input.nextInt();
    return getMinutes;      
}

public int getAMOrPM() {
    Scanner input = new Scanner(System.in);
    int amOrPm;
    System.out.println("ENTER AM or PM FOR YOUR ALARM: ");
    amOrPm = input.nextInt();
    return amOrPm;

}

public void getSystemTime() {
    DateFormat df = new SimpleDateFormat("HH:mm");
    Calendar calobj = Calendar.getInstance();
       System.out.println(df.format(calobj.getTime()));
}

} // end of testClass

定义一个调用构造函数类的主方法

 public static void main(String[] args)
    {
        testClass r = new testClass();
    }

要调用某个功能，您需要添加一个括号。所以转到这个

 public testClass() {
    System.out.println("ALARM SET TO: " + getHour()+":" + getMinutes() + getAMOrPM());
   }

如何将变量调用到另一个方法中？
