它分成三个部分 前面的"4"，表示f1的第4行有变化 中间的"c"表示变动的模式是内容改变 change ，其他模式还有"增加" a，代表addition 和"删除" d，代表deletion 后面的"4"，表示变动后变成f2的第4行。 Diff -c f1 f2. F1 2012-08-29 16:45:41.000000000 0800.

http://www.soulmachine.me/blog/2015/06/22/deserialize-a-json-string-to-a-binary-tree
Deserialize a JSON String to a Binary Tree. We know that Jackson is very convenient to deserialize a JSON string into a. But how to deserialize a JSON String to a binary tree? The definition of binary tree node is as follows:. The JSON String is as follows:. Value": 2, "left": { "value": 1, "left": null, "right": null }, "right": { "value": 10, "left": { "value": 5, "left": null, "right": null }, "right": null } }. The above JSON string represents a binary tree as the following:. Value : 2, n. Left : { n.

Calling C Code From Java Using JNI. This blog is a fork of http:/ stuf.ro/calling-c-code-from-java-using-jni. With some errors fixed and C support added. In this tutorial we’ll be creating a Java application calling code from a native library. We’ll have a Java application called. Which will call the function. From a shared library named. Using Java Native Interface. First off, we’ll create a file named. Make the JVM aware of a function defined externally, named. Load an external library called. Alright,...
