the Debug feature of Eclipse. Well, you now have the technical basis for reading the source code.I recommend starting with the JDK source code, which integrates directly with Eclipse and does not require any configuration.You can start with the JDK Toolkit, which is the Java version of data structures and algorithms that we learned, such as the list interface and ArrayList, LinkedList implementations, HashMap and TreeMap, and so on. These data struct

The Java language has been at the forefront of programming languages since its appearance. One major reason is that it is related to the platform where Java applications run. We all know that Java applications run on java virtual machines. This greatly reduces the frequency of dealing with

want Masons silently for themselves, for the family for the future lay the groundwork. As you can see, string is a class that does not need to create a new object using new. It is immutable (Constant), and its value (like "ABC" is created, cannot be changed). Naturally, string actually implements the function of the sequence of the basic type char, so the Chinese name "string". Here it is possible to doubt that Mason will find the JDK source code evidence to show you: This code is from the JDK

The JDK, Java Development Kit, is intended for developers and provides a Java development environment and a running environment. The JRE, the Java runtime enviroment, is a Java-oriented program user. The JVM, the Java Virtul Machine.java virtual machine, is the most centra

In many Java interviews, we often see a review of the Java class loading mechanism, such as the following question:Classgrandpa{Static {System.out.println ("Grandpa in Static code block"); }}ClassFatherExtendsgrandpa{Static {System.out.println ("Papa in Static code block"); } public static int factor =25; PublicFather () { System.out.println ("I am Father ~");}} class son extends father{static { System.out.

Java garbage CollectionThe Java GC (garbage Collection, garbage collection, garbage collector) mechanism is one of the main differences between Java and C + +. There is an automatic memory management and garbage cleaning mechanism in the Java virtual machine. In a nutshell,
