Finally Java 8 includes a decent API for it in the java.util package. Here is a short introduction of this new API (apparently it has a little more than the regular encode/decode API) public class BubbleSort { /** * N个数字要排序完成,总共进行N-1趟排序,每i趟的排序次数为(N-i)次,所以可以用双重循环语句,外层控制循环多少趟,内层控制每一趟的循环次数。 * @param args */ public static void main(String[] args) { int arr[] = {26,15,29,66,99,88,36,77,111,1,6,8,8}; for(int i=0;i < arr.length-1;i++) {//外层循环控制排序趟数 for(int j=0; j< arr.length-i-1;j++) { //内层循环控制每一趟排序多少次 // 把小的值交换到前面 if (arr[j]>arr[j+1]) { int temp = arr[j]; arr[j] = arr[j+1]; arr[j+1] = temp; } } System.out.print("第"+(i+1)+"次排序结果:"); //列举每次排序的数据 for(int a=0;a<arr.length;a++) { System.out.print(arr[a] + "\t"); } System.out.println(""); } System.out.println("最终排序结果:"); for(int a = 0; a < arr.length;a++) { System.out.println(arr[a] + "\t"); } } }Hantn   Hantn 但是对于大型项目开发或者框架设计,用设计模式来组织代码显然更好。 关于本教程. 本教程虽然命名为Java设计模式,但是设计模式并不是 Java 的专利,它同样适用于 C++、C#.. 本栏目为您提供:关注java代码分享,提供java代码片段,java最新代码分享,代码片段

  3. 异步对于设计大规模快速响应的应用是至关重要的。异步回调模型带来了很多的好处;你可以依赖你的异步回调方法来执行昂贵的I/O操作而你的处理器可以执行其它任务。然而虽然在Java和C#中提供了异步的支持,异步编程并不总是那么容易实现。异步方式的使用要谨慎: 你应该清楚什么时候可以用和什么时候不该用。
  4. 我们需要异步来消除阻塞模型。其实异步编程模型可以使用同样的线程来处理多个请求, 这些请求不会阻塞这个线程。想象一个应用正在使用的线程正在执行任务, 然后等待任务完成才进行下一步。 log框架就是一个很好的例子:典型地你想将异常和错误日志记录到一个目标中, 比如文件,数据库或者其它类似地方。你不会让你的程序等待日志写完才执行,否则程序的响应就会受到影响。 相反,如果对log框架的调用是异步地,应用就可以并发执行其它任务而无需等待。这是一个非阻塞执行的例子。
  5. J2SE,全称为Java 2 Standard Edition。Java 2平台包括:标准版(J2SE)、企业版(J2EE)和微缩版(J2ME)三个版本。J2SE即Java 2的标准版,主要用于桌面应用软件的开发。
  6. Java 7中提供了Fork/Join框架, 可以将一个大的task分割成很多可以并行执行的小task。Java 8中parallelStream内部利用Fork/Join执行并发操作。如果使用Java 8,可以使用CompletableFuture类(可以参考我写的另外一篇文章Java CompletableFuture 详解),它提供了更多的异步的控制,如果你还在使用较老版本的Java,可以使用Guava等框架提供的Future。

下面的代码片段定义了一个包含两个方法的接口。 一个是同步方法,另外一个是异步方法。数组的元素类型和数组的大小都是确定的,所以当处理数组元素时候,我们通常使用基本循环或者 For-Each 循环。Explanation why it is so: I think that javaw opens an internal process in the OS (adequate using the java.lang.Process class), and transfers a known output redirection to this process. If no redirection is given on the command line, nothing is redirected and the internal started process for javaw doesn't have any console outputs. The behavior for java.lang.Process is similar. The virtual machine may use this internal feature for javaw too.含博客讲解和源码实例,采用 maven 构建,分模块学习,涉及反射,代理,多线程,IO,集合类等核心知识。 9 java.exe is associated with the console, whereas javaw.exe doesn't have any such association.
