The essence of packaging is compression, and jar packages and war packages are zip packages, which is what they have in common.

JAR
Jar is the method commonly used by third-party libraries before Maven came out; it
is available for invocation in the form of a zip package.
Use the command java -jar xxx.jar to execute.
WAR

war package can be used in the form of zip package, can also be used in decompressed form (usually the decompressed war package).

POM
