Java Interview Questions Made Easy #2 What is the Classloader

Описание: The Java ClassLoader is used to load .class files into the JVM at runtime.

There are three main types of classloaders:

Bootstrap classloader (loads all the Java core libraries like java.lang)

Extension classloader (loads classes defined in jar files at
$JAVA_HOME$\lib\ext)

System classloader (loads classes from the CLASSPATH)*
*All classes that you write in your program and all the dependencies from imported JARs are loaded by the System class loader
