The Dalvik virtual machine relies on the underlying POSIX-compliant operating system, which can simply complete process isolation and thread management. It has efficient use of memory and high performance on Low-speed CPUs. Each Android application has a separate Dalvik virtual machine instance at the bottom, and its c

This blog post focuses on the process of loading a class from a Java virtual machine, some of which are referred to in-depth understanding of Java virtual machines. In order to avoid the tedious explanation, in order to let the reader after reading this article can thoroughly understand the class loading process, first of all to see a piece of Java code, we start
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 Java
Virtual machine class loading mechanismThe virtual machine loads the data of the description class from the class file into the memory, verifies the data, parses and initializes it, and finally forms the Java type that can be used directly by the virtual

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

When you encounter the 4 bytecode directives of new, getstatic, putstatic, or invokestatic, if the class has not been initialized, you need to trigger its initialization first. The most common Java scenario for generating these 4 instructions is when instantiating an object using the New keyword, reading or setting a static field of a class (except for a static variable that is final decorated, has placed the result into a constant pool at compile time), and when i
Java heap memory is divided into two parts of the new generation and the old generation, the new generation mainly uses the replication and labeling-clearing garbage collection algorithm, the old generation mainly use tag-sorting garbage collection algorithm, so in Java virtual for the new generation and the old generation of different garbage collectors, JDK1.6 in sun The garbage collector for the hotspot virtual
