// String srcPath = "D:\\test";// 被压缩文件夹
String srcPath = "D:\\test.txt";// 被压缩文件
String destPath = "D:\\test.rar";// 压缩后文件
String rarexePath = "C:\\Program Files\\WinRAR\\Rar.exe"; // 电脑系统中WinRAR安装路径 未安装出错
String[] rarcmd = { rarexePath, "a", destPath, srcPath };
Runtime rt = Runtime.getRuntime();
rt.exec(rarcmd);

String srcPath = "D:\\test.rar";// 压缩文件
String destPath = "D:\\";// 解压缩后路径
String unrarexePath = "C:\\Program Files\\WinRAR\\UnRAR.exe"; // 电脑系统中WinRAR安装路径 未安装出错
String[] unrarcmd = { unrarexePath, "x", srcPath, destPath };
Runtime rt = Runtime.getRuntime();
rt.exec(unrarcmd);
