Working with and importing external libraries / frameworks in Java -
firstly n00b question. being junior dev i've never needed import , work other java frameworks. standard library enough me write classes needed write.
but getting exposed more "advanced" concepts, need start working external frameworks, e.g. json java, apache's httpclient java , on. , i'm looking basic understanding on how works , how go importing these libraries can start working classes...
so initial understanding each of these fraemworks provide .jar file contains classes framework. import project , lo , behold you'll able use classes/library in project importing e.g. 'import org.json.*;'
is understanding correct?
correct.
you add libraries classpath , able use classes these libs. how add libs classpath depends on actual development environment. if use apache maven example, have define dependencies (libs) in projects pom.xml
, maven downloads them automatically you.
hth,
