问题

大家好，我正在使用 A.Studio 的最新版本，但我需要一些帮助。
我已经安装了 Android Studio 并想要进行一些检查。我创建了一个名为 Main.java 的基本代码。
我为了检查它而写了下面这些代码。我已经进行了多次研究，但是我无法解决这个问题，我需要帮助。

```java
public class Main {
    public static void main(String[] args){
        System.out.println("Testing Java");
    }
}

然后我调试了代码，A.S 给我发送了错误日志。您可以在下面看到。
