What is .jar

Question

difference between. jar and .java?

Answer 1

Files with the .java extension are Java programs (source code), while files with the .jar extension are Java archives (compressed Java programs for distribution and installation). So the programmer writes code and saves it in a .java file. When the whole program is done, the .java file is compressed into a .jar archive, who is sent to the user. The user uses the .jar file to install the program.
