Within Java, what are the differences between Path and Classpath variables?
This is a common format of a technical question. Technical questions ask you about concepts or items related to the work you do. They sometimes ask you to compare similar concepts or to describe how they are used. When answering technical questions using this format, you should first define the terms you were asked about. You then either compare them or describe how they are used. You may provide an example relevant to the Salesforce job posting if it helps illustrate your answer.
"Both Path and Classpath are environmental variables which the operating system uses to locate executables. The OS locates the executables in a directory location, which is defined by these variables. The difference between a Path and Classpath variable is that a classpath is very specific to Java and can be defined as a directory, ZIP file, JAR file or another type of variable. This is critical since you need to select the appropriate Path based on what Salesforce API you want to use."

PATH is used to set all of the environment variables used for the executable code. Examples would be the javac.exe, java.exe, etc. CLASSPATH is used to load all of the java .class files. PATH is used by the OS while CLASSPATH is used by Application CLASSLOADER to load the .class file.
