1. Class Loader
The ClassLoader is used when the program is running to use a class, and the class loader loads the bytecode of that class into memory for execution.
Java Virtual machines can install multiple classloader, the system defaults to three main class loaders, each class loader is responsible for loading classes in different locations

Class Loader OverviewThe ClassLoader is responsible for loading all classes, and the system generates an Java.lang.Class instance for all classes that are loaded into memory. Once a class is added to the JVM, the same class is not added again. Just as an object has a unique identity, a class that is loaded into the JVM also has a unique identity. In Java, a class is identified with its fully qualified class name (including the package name and class n

Sql*loader is an Oracle-provided tool for data loading, which is more suitable for business analysis type databases (data warehouses), can handle multiple format flat files, and bulk data loading is more efficient than traditional data insertion
The schematic diagram is as follows:
Control file: A file (the most important file) used to control how data is imported.
Parameter file (optional)
Data files: Flat file where source data is placed

Source: http://www.ibm.com/developerworks/cn/java/j-lo-classloader/The ClassLoader (class loader) is a very important concept in java™. The ClassLoader is responsible for loading the Java class's byte code into the Java virtual machine. In this paper, the basic concepts of Java ClassLoader are introduced in detail, including the proxy mode, the concrete process of loading class and the thread context class loader

After Reading Wang Sen's Java deep adventure, he made a simple study note.
1. the Java class loader loads classes on demand only when a class is to be used (a class is instantiated using the new keyword, the Class Loader loads the class and initializes it.
Class main:
Java code
Public class main {
Public static void main (string [] ARGs ){
A A = new ();
A. Print ();
B = new B ();
B. Print ();
}
}
The ClassLoader is divided into the following three types, from the top to the bottom level .:(1) Start class loader (Bootstrap ClassLoader)This classloader is responsible for loading the class library that is stored under java_home/lib or in the path specified by the-xbootclasspath parameter into the virtual machine memory. The startup ClassLoader cannot be referenced directly by a Java program.(2) Extension class

Class Loader
Java class loaders are dynamically loading the required classes in the JVM at run time, and the Java class loader is based on three mechanisms: delegate, visible, single.
Load the. class files under the classpath into memory and become bytecode after processing, which is done by the ClassLoader.
A delegate mechanism refers to passing a request for an add-in class to the parent

Of course, you can also customize the ClassLoader, and the custom loader must inherit ClassLoader.All ClassLoader in a Java Virtual machine are
