以下是您要翻译的部分：

Trying to follow tuto but seems not working for me. It's Maven tuto, you can go to 11min to see the original code:

[Tuto Link Maven ][1]

Please find below my code:

package org.example.demo;

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
import org.apache.commons.io.input.ClosedInputStream;

/**
 * Hello world!
 *
 */
public class App {
    public static void main( String[] args ) throws IOException
    {
        System.out.println( "Hello World!" );
        
        Properties vProp = new Properties();
        InputStream vInputStream = null;
        try {
            vInputStream = App.class.getResourceAsStream("/info.properties");
            vProp.load(vInputStream);
            
        } finally {
            if (vInputStream != null) {
                vInputStream.close();
            }
        }
    
        System.out.println("Application version :"+vProp.getProperty("org.example.demo.version+?"));
    }

**得分**: 1

`vProp.load(vInputStream)` 和 `vInputStream.close()`。

我还建议使用 try-with-resources 处理 vInputStream，无需调用 close 方法：

```java
try (InputStream vInputStream = App.class.getResourceAsStream("/info.properties")) {
    vProp.load(vInputStream);
}

try (InputStream vInputStream = App.class.getResourceAsStream("/info.properties")) {
    vProp.load(vInputStream);
}
