What do you mean by Class loaders?

[RH-Calvin]

The Java Class Loader is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine. Usually classes are only loaded on demand. The Java run time system does not need to know about files and file systems because of classloaders.

Classloader is a part of the JRE(java runtime environment) that dynamically load java classes into the java virtual machine (JVM) on demand.

Type of java classloader are three

1. Bootstrap Class Loader – It loads JDK internal classes, typically loads rt.jar and other core classes for example java.lang.* package classes
2. Extensions Class Loader – It loads classes from the JDK extensions directory, usually lib/ext directory of the JRE.
3. System Class Loader –Loads classes from system classpath, that can be set while invoking a program using -cp or -classpath command line options.

ClassLoader in Java is a class that is used to load class files in Java.

Java ClassLoader is used to load classes at runtime. In other words, the JVM executes the linking process at runtime. Load the classes into the JVM as needed. If a loaded class depends on another class, that class will also be loaded.

The Java ClassLoader is a part of the Java Runtime Environment that dynamically stores Java classes into JVM (Java Virtual Machine).

Hello,

Java ClassLoader is used to load the classes at run time. In other words, JVM performs the linking process at runtime. Classes are loaded into the JVM according to need. If a loaded class depends on another class, that class is loaded as well. When we request to load a class, it delegates the class to its parent. For more details visit here.

The Java ClassLoader is a part of the Java Runtime Environment that dynamically loads Java classes into the Java Virtual Machine. The Java run time system does not need to know about files and file systems because of classloaders. Java classes aren't loaded into memory all at once, but when required by an application

[nihitthakkar]

An Application Class Loader is also known as a System Class Loader. It loads the Application type classes found in the environment variable CLASSPATH, -classpath or -cp command line option. The Application Class Loader is a child class of Extension Class Loader.

Class loaders are responsible for loading Java classes during runtime dynamically to the JVM (Java Virtual Machine). Also, they are part of the JRE (Java Runtime Environment). Hence, the JVM doesn't need to know about the underlying files or file systems in order to run Java programs thanks to class loaders.
