Java:public class TestJNI{ static { System.loadLibrary("TestJNI"); } public native DiskInfo[] getStructArray
Linux平台(CentOS为例)1、修改环境变量配置文件(1) 如果是仅当前用户生效,就编辑 ~/.bashrc 或 ~/.bash_profile;(2) 如果是所有用

1、用数组返回多个对象可以用Object[]
/** * 读入字符串,遇到某一字符结束读入 * int.txt: 中国123美国abc日本;123 */import java.io.*;class Test{ public static void main(String[] args) throws IOException { FileReader in = new FileReader("in.txt"); int

/** * example-01: GetStringUTFChars() * * 代码出自《The Java Native Interface Programmer’s Guide and Specification》 * 运行平台:Windows XP *//** * The example program, Prompt.java , contains a * native
/** ************Java字节流与字符流 * 1、测试环境:Fedora("in.txt"文件的编码为utf-8,“中”占3个字节) * 2、Linux下如何查看文件编码格式:vim下[:set fileencoding] * 3、以单字节十六进制形式查看文件:od -t x1 in.txt*//* "in.txt"内容中abcd中*///字节流:read()每次读
