Java Collection frameworks such as set, map, and list do not provide any simple method for initialization. Each time a set is created, values must be added one by one. For example CopyCode The Code is as follows: Set Letter. Add ('A '); Letter. Add ('B '); //... Very tedious. But use an anonymous internal class. It can be slightly simpler. Copy

Recently, because of the work needs, learning the Ligerui framework. However, because in the company, we just as the lowest level of the yards, so the environment has been set up, we are the yards of farmers are directly to get the project, and then in other people's frame constantly CTRL + C, CTRL + V, and then tinkering. So in order to get out of this dilemma, decide to use a simple servlet to build a Ligerui, and then test how ligerui this thing is

the element to the preceding element, saving the element to a temporary variable if it is smaller than the preceding element, then moving the preceding element back, and then inserting the element into the appropriate location. After each sort completes, the element on the left side of the index must be ordered, but it can also be moved. The lower the inverted array, the higher the sorting efficiency of the algorithm. Note: Inverted: 5 3 6 2 The inverted entry is 5-3 5-2 3-2 6-2 Sample Demo:
