[FIXED] How to set the class path in Eclipse and Android Studio

Issue

I've heard that you can use classpath to use classes in other libraries. I googled about this and all results tell me to use the command line to compile the program and specify a classpath. But who would use command line to compile java programs nowadays?

I am using eclipse and Android Studio. I mean they are IDEs so they surely can set the classpath very easily, right?

Also, I want to know the word "library" in this context is just a jar file , right?

Solution

In Eclipse:

Right-Click on the Project → Build Path → Configure Build Path. Under Libraries tab, click Add Jars or Add External JARs and give the Jar.

Android Studio: from Android Studio: Add jar as library?

1. Right click on the module in the left hand panel and choose Open Module Settings.
2. On the left panel of the dialog, choose Libraries.
3. Click the + sign above the panel second from the left -> Java
4. Select your local jar and add it to the project.
