javac cannot find .java file

javac cannot find the .java file

1. Problem description

I just started Java. When I used javac to compile the .java file, I encountered the problem that the file cannot be found, as shown in the following figure:

javac cannot find .java file

2. Problem causes and solutions

1. When writing Java source code with Notepad, there is a .txt hidden suffix

Solution: Open Folder Options-> Check the file extension-> Rename the Java file to delete the .txt suffix.

2. The current compilation path is not the Java class path

Solution: Use cd to switch to the correct Java class storage path.

3. The main() method is not defined in the Java class or there is an error in the defined main() method

Solution: Check whether main() is correct.
