JAVA线程的创建方式

JAVA创建线程的两种方式 （我看网上有一部分帖子写JAVA创建线程有三种方式，其实是不完全正确的。java的官方文档中明确声明了只有两种创建方式，第三种使用线程池的其实并不算是，他的原理也是使用了implement Runnable的方式。） There are two ways to create a new thread of execution. One is to declare a class to be a subclass of Thread . This subclass should override the run method of class Thread . An instance of the subclass can then be allocated and started. For example, a thread that computes primes larger than a stated value could be written as follows: （有两种方法，可以创建新的线程。一种是将类声明为Thread的子类。这个子类的实例将会等待被分配和启动。例如，计算素数大于指定值的线程可以编写如下：） class PrimeThread extends Thread { long minPrime; PrimeThread

【第一步】： 修改module下的build.gradle buildTypes { release { // 是否进行混淆 minifyEnabled true // 混淆文件的位置 // proguard是一个压缩、优化和混淆Java字节码文件的免费的工具 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } 【第二步】： 在proguard-rules.pro中添加: #指定代码的压缩级别 -optimizationpasses 5 #包明不混合大小写 -dontusemixedcaseclassnames #不去忽略非公共的库类 -dontskipnonpubliclibraryclasses #优化 不优化输入的类文件 -dontoptimize #预校验 -dontpreverify #混淆时是否记录日志 -verbose # 混淆时所采用的算法 -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* #保护注解 -keepattributes *Annotation* # 保持哪些类不被混淆 -keep public class * extends

“.class” way of obtaining Class - does it initialize the class?

问题 Question is about Java . There are three ways of obtaining classes of a type (note that code is just a collection of snippets for demonstration): Class c1 = Class.forName("com.mypkg.MyClass"); //assumes initialize = true // - OR - Class c1 = Class.forName("com.mypkg.MyClass", true/false, this.getClass().getClassLoader()); Class c2 = com.mypkg.MyClass.class; // - OR - import com.mypkg.MyClass; Class c2 = MyClass.class; MyClass mc = new MyClass(); Class c3 = mc.getClass(); My question is about

Following code gives correct output, If I declare variables i and j , Like int i, j; class A { int i, j; public: A(int val) : i(val), j(i + 1) { cout<<i<<endl<<j<<endl; } }; But If I declare variable i and j , like int j, i; . then j print garbage value . class A { int j, i; public: A(int val) : i(val), j(i + 1) { cout<<i<<endl<<j<<endl; } }; So, Is it depend on order of
