There are many tools to implement multi-boot, such as system commander, Lilo of Linux, and OS loader of WindowsNT. There are two principles: Modify the MBR (Master Boot Record) and use the JMP command to jump to your own code at the end of the MBR to control the guiding process; another method is to modify the Boot Code of the first sector in the primary partition to implement multiple boot operations. Here the MBR, that is, the primary Boot Record, r

JAVA Class Loader section 14thToday we will load the first phase of the class loading mechanism in 5 stages, also called loading . In order to read the good distinction, the following is called loading.The first step in loading is to get a binary byte stream, which can be obtained from a read. class file, or it can receive a stream of bytes sent from someone else on the network. Anyway, you can enter this phase as long as the virtual machine's specifi

In an Oracle database, we typically use the following methods when replicating or migrating between tables in different databases:1. The record of a table is exported as a semicolon-delimited INSERT statement and then executed into table B2. Create a dblink between the databases and then use CREATE TABLE B as SELECT * from [email protected] where ..., or INSERT INTO B SELECT * FROM C1>[email protected] where ...3. Exp A, then imp to form B, exp can add query conditions4. Program implementation S

This series learns notes for deep Java virtual machines (Zhou Zhiming) The code module that obtains a binary byte stream that describes this class is called a class loader through the fully qualified name of a class. For any class, it is necessary to establish its uniqueness in the Java Virtual machine, together with the class loader that loads it and the class itself. Popular understanding: Compare t

Java performance involves many things. I always wanted to write a summary. In the first part, we will introduce the class loader, which is mainly used to load the required classes when the Java virtual machine is running. I. These classes have two parts: one is the Java class in your application, and the other is the class file in Java API. The loader has two important tasks: 1. Loading: locate a class an
