When I try to run in Android Studio, I get the following error message:

java

public class Test1
{
    public static void main (String [] args)
    {
        System.out.print ("Hello World");
    }
}

After getting this error, I tried to recreate the project or reinstall Android Studio, but I get the same error.

The version of Android Studio is 4.0.1.
