p2

Our company uses Maven. We use the Nexus repository manager in order to store our snapshots and releases. Currently, we are developing a product based on Eclipse. We use Tycho to do that. The problem is the following: In our Eclipse-based product we have many features. Our idea is build each feature (or group of features) separately and put them in internal p2 repositories. When one features requires another feature, we point the target platform to necessary internal p2 repository. Currently, we build application with Tycho. We make our features "deployable", so Tycho produces a P2 site in

思路：使用归并排序，每一轮归并后都局部有序，可以利用这个，减少时间复杂度 小和问题 关键代码： public static int mergeSort(int[] arr, int left, int right) { if (left == right) { return 0; } int mid = ((right - left) >> 1) + left; return mergeSort(arr, left, mid) + mergeSort(arr, mid + 1, right) + merge(arr, left, mid, right); } public static int merge(int[] arr, int left, int mid, int right) { int[] help = new int[right - left + 1]; int i = 0; int p1 = left; int p2 = mid + 1; int res = 0; //每经过一轮归并，数据从小到大排序。在每一轮归并中，计算左边比右边小的数的总和 while (p1 <= mid && p2 <= right) { if (arr[p1] < arr[p2]) { res += arr[p1] * (right - p2 + 1); } help[i++] = arr

I just downloaded Eclipse SDK 3.5.1 and want to install some add ons such as GEF, EMF, etc. I downloaded all the zip files for everything I needed and decided to install them in the dropins folder. I read http://wiki.eclipse.org/Equinox_p2_Getting_Started and structured my dropin folder as specified: eclipse/ dropins/ emf/ eclipse/ features/ plugins/ gef/ eclipse/ features/ plugins/ ... etc ... When I start up Eclipse it does not recognize any of the features or plugins I have put into the structure above. Any ideas? I suggest that you try to install those features via the update manager.

浅拷贝 浅拷贝是按位拷贝对象，它会创建一个新对象，这个对象有着原始对象属性值的一份精确拷贝。如果属性是基本类型，拷贝的就是基本类型的值；如果属性是内存地址（引用类型），拷贝的就是内存地址 ，因此如果其中一个对象改变了这个地址，就会影响到另一个对象。 例如： /* 拷贝构造方法实现浅拷贝 */ public class CopyConstructor { public static void main(String[] args) { Age a=new Age(20); Person p1=new Person(a,"摇头耶稣"); Person p2=new Person(p1); System.out.println("p1是"+p1); System.out.println("p2是"+p2); //修改p1的各属性值，观察p2的各属性值是否跟随变化 p1.setName("小傻瓜"); a.setAge(99); System.out.println("修改后的p1是"+p1); System.out.println("修改后的p2是"+p2); } } class Person{ //两个属性值：分别代表值传递和引用传递 private Age age; private String name; public Person(Age age,String name) {
