millis

## Clock Class millis()方法 **(**Clock Class millis() method**)** ##

*  **millis() method** is available in java.time package.
    
    **millis()方法**在java.time包中可用。
 *  **millis() method** is used to represent the current instant in milliseconds of this Clock.
    
    **millis()方法**用于表示此Clock的当前瞬间(以毫秒为单位)。
 *  **millis() method** is a non-static method, it is accessible with the class object and if we try to access the method with the class name then we will get an error.
    
    **millis()方法**是一种非静态方法，可通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。
 *  **millis() method** may throw an exception at the time of returning instant in milliseconds.
    
    **millis()方法**在以毫秒为单位返回瞬间时可能会引发异常。
    
    **DateTimeException**: This exception may throw when no instant couldn't be generated (i.e. invalid instant is used with this Clock).
    
    **DateTimeException** ：当无法生成任何瞬间时(例如，此Clock使用无效的瞬间)，可能会引发此异常。

**Syntax:**

**句法：**

public long millis();

**Parameter(s):**

**参数：**

*  None
    
    没有

**Return value:**

**返回值：**

The return type of this method is long, it returns the current instant in milliseconds that is used with this Clock.

此方法的返回类型为long ，它返回此Clock使用的当前瞬间(以毫秒为单位)。

**Example:**

**例：**

// Java program to demonstrate the example 
    // of millis() method of Clock
    
    import java.time.*;
    
    public class MillisOfClock {
        
        public static void main(String args[]) {
        
            // Instantiates two ZoneId for Accra and Asmara
            ZoneId zone_1 = ZoneId.of("Africa/Accra");
            ZoneId zone_2 = ZoneId.of("Africa/Asmara");
    
            // Initialize two Clock objects  
            Clock cl1 = Clock.system(zone_1);
            Clock cl2 = Clock.system(zone_2);
    
            // returns the current millisecond 
            // instant value of this Clock cl1
            long cl_millis = cl1.millis();
    
            // Display cl1 millis instant
            System.out.println("cl1.millis(): " + cl_millis);
    
            // returns the current millisecond 
            // instant value of this Clock cl2
            cl_millis = cl2.millis();
    
            // Display cl2 millis instant
            System.out.println("cl2.millis(): " + cl_millis);
        }
    }

**Output**

**输出量**

cl1.millis(): 1589396151574
    cl2.millis(): 1589396151628
