javac: Compile several `.java` files.

javac

$ javac ${file1-java} ${file2-java} ${file3-java}

try on your machine

The given command is using the "javac" command-line tool to compile multiple java source files at once.

Here, "${file1-java}", "${file2-java}", and "${file3-java}" are placeholders for the actual file names. The placeholders are being used in a way that allows the command to be flexible, so you can replace them with the actual file names when using the command.

To use the command, you need to replace "${file1-java}", "${file2-java}", and "${file3-java}" with the respective names of your java source files. The command will then compile all the specified files in one go.

For example, if you have three Java source files named "MyFile1.java", "MyFile2.java", and "MyFile3.java", you can use the command like this:

javac MyFile1.java MyFile2.java MyFile3.java

This will compile all three java source files in a single process, allowing you to save time and effort manually compiling each file one by one.
