示例1:

// Java code to illustrate 
// getTime() method 
  
import java.util.*; 
  
public class Calendar_Demo { 
  
    public static void main(String args[]) 
        throws InterruptedException 
    { 
  
        // Creating a calendar 
        Calendar calndr1 
            = Calendar.getInstance(); 
  
        // Displaying the current time 
        System.out.println("The Current"
                           + " Time is: "
                           + calndr1.getTime()); 
  
        // Adding few delay 
        Thread.sleep(10000); 
  
        // Creating another calendar 
        Calendar calndr2 = Calendar.getInstance(); 
  
        // Displaying the upcoming time 
        Date dt = calndr2.getTime(); 
        System.out.println("The upcoming"
                           + " time is: " + dt); 
    } 
}

輸出：

The Current Time is: Wed Feb 20 14:40:37 UTC 2019
The upcoming time is: Wed Feb 20 14:40:47 UTC 2019

示例2:

// Java code to illustrate 
// getTime() method 
  
import java.util.*; 
  
public class Calendar_Demo { 
  
    public static void main(String args[]) 
        throws InterruptedException 
    { 
  
        // Creating a calendar 
        Calendar calndr1 
            = Calendar.getInstance(); 
  
        // Displaying the current time 
        System.out.println("The Current"
                           + " Time is: "
                           + calndr1.getTime()); 
  
        // Adding few delay 
        Thread.sleep(5000); 
  
        // Creating another calendar 
        Calendar calndr2 = Calendar.getInstance(); 
  
        // Displaying the upcoming time 
        Date dt = calndr2.getTime(); 
        System.out.println("The upcoming"
                           + " time is: " + dt); 
    } 
}

輸出：

The Current Time is: Wed Feb 20 14:40:50 UTC 2019
