How can javac identify the CMD symbol without making any alterations?

edit

The CMD symbol, which is typically used to indicate the start of a command in Windows Command Prompt or PowerShell, does not need to be identified by the javac compiler as it is not a part of Java syntax.

Instead, it is the responsibility of the operating system to recognize and interpret the CMD symbol when it appears in a command line interface, and to execute the subsequent command or series of commands accordingly.

In other words, the use of the CMD symbol is outside the scope of the Java programming language and has no direct impact on the compilation or execution of Java code.
