java调用本地程序

例一：

try {
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("systeminfo");
InputStreamReader ir = new InputStreamReader(p.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String line;
while ((line = input.readLine()) != null) {
System.out.println(line);
}
} catch (java.io.IOException e) {
System.err.println("IOException " + e.getMessage());
}

例二：

Runtime rt = Runtime.getRuntime();
try {
Process p = rt.exec("notepad");
} catch (IOException ex) {
Logger.getLogger(ZipOp.class.getName()).log(Level.SEVERE, null, ex);
}
