### 新建module-info.java文件 ###

输入**module-info.java**内容如下：

module helloworld {
        exports com.hello;
    }

### 新建`HelloWorld.java`文件 ###

package com.hello;
    
    import java.util.Calendar;
    
    public class HelloWorld {
    
        public String sayHelloWorld() {
    
            return String.format("%s, now is %s", "hello world", Calendar.getInstance().getTime());
        }
    
    }

### 最终模块内容如下 ###

### 参照上述步骤新建模块helloworldclient ###

其中，`module-info.java`内容如下:

module helloworldclient {
        requires com.hello;
    }

**HelloWorldClient.java**内容如下:

package com.hello.client;
    
    import com.hello.HelloWorld;
    
    public class HelloWorldClient {
        public static void main(String[] args) {
            HelloWorld hello = new HelloWorld();
            System.out.println(hello.sayHelloWorld());
        }
    }

### 执行HelloWorldClient，得到如下结果 ###

hello world, now is Thu Nov 15 11:52:29 CST 2018
