ReturnAddress types (address to a byte-code instruction: function return address) of the compile-time. The memory space required by the local variable table is determined at compile time, when a method is entered, The local variable control that the method needs to allocate in the stack frame is completely determined and cannot be changed dynamically. A variable slot (Variable Slot) is the smallest unit of

Deep understanding of Java Virtual Machine-Chapter 3: deep understanding of Java Virtual Machine 1. Overview 2. Is the object dead? Reference Counter Add a reference counter to the object. When there is a reference, add 1 to the counter. When the reference is invalid, the counter minus 1. Objects whose counter is 0 at

Java Virtual Machine command dup understanding, Java Virtual Machine dup For example: 1 public class ExceptionTest{2 3 void cantBeZero(int i) throws Exception{4 throw new Exception();5 6 }7 8 } The bytecode command after the above Code is compiled is as follows: 1 void cantBeZero(int) throws java.lang

Java Virtual Machine: runtime volume pool, Java Virtual Machine volume pool1. Introduction to the runtime frequent pool Runtime Constant Pool, which is part of the method area. In addition to the description of the version, field, method, and interface of the Class, the Class file also contains the Constant Pool Table

Java Virtual machine-virtual machine byte code execution engineAll Java Virtual machine execution engines are consistent: the input is a bytecode file, processing is the equivalent process of bytecode parsing, the output is the execution results.Run-time stack frame structur

Schematic diagram of the Java Virtual Machine ---- JVM runtime data zone, virtual machine ---- jvm JVM Runtime data zone (JVM Runtime Area)In fact, it refers to the division and allocation of computer memory space during JVM running. This article will discuss the JVM runtime data zone through the following topics. Topic 1.JVM runtime data ZoneIn what? Topi

Google launched the Android SDK at the end of 2007 as an important feature of the Android system, and the Dalvik virtual machine was the first to come into view. Its efficient use of memory and its high performance on low-speed CPUs are truly impressive. Relies on the underlying POSIX-compliant operating system, which can simply complete process isolation and thread management. Each Android app will have a standalone Dalvik virtual

Today began the actual combat Java Virtual Machine two: "Virtual machine working mode."Total of 5 Series "Heap overflow processing" in one of the actual Java virtual machines Virtual machine working mode for Java Virt

The first part goes into the Java1.java technology systemSun's officially defined Java technology System includes several components: Java Program Set Language Java virtual machines on a variety of hardware platforms class file format Java API Class Libr

Some people think that the Dalvik virtual machine is a Java virtual machine, because the Android programming language is exactly the Java language. However, this statement is not accurate, because the Dalvik virtual machine is not implemented in accordance with the

Since the work above, the program because the code more write more, become more and more bloated, the efficiency will become lower, so I always like to constantly optimize the program structure outside, memory optimization and performance tuning.To make memory optimizations and performance tuning for Java programs, you need to understand the internal principles of virtual machines and understand the benefits of Ja
