I came across a particularly odd exam question. The question is:

"List the 4 JAR files needed by the JRE".

I find this weird because when I look in my jdk/jre folder, there is a whole lot more than 4 jar files. So my question is, is the above mentioned question invalid? Or am I not understanding exactly what the question is asking? And if so, what are the 4 required jar files?

Not sure if this answers the question. The question can be basic or can be a lot deeper.

But AFAIK, some important Jar's are -

  1. rt.jar
  2. localedata.jar
  3. tools.jar
  4. dt.jar**

Reason being, they are an important part of JDK and JRE hirarchy. You can google about them if required.

  • thanks, for a sec i thought it was a trivial question – BiGGZ Sep 14 '16 at 16:50
  • Do you know why localedata.jar would be a required JAR file? It's marked as optional in http://www.oracle.com/technetwork/java/javase/jre-8-readme-2095710.html – Jack Mar 04 '18 at 18:52
