利用反射机制调用main函数并传递参数

public void testGenMallet() {try {Method methods = Csv2Vectors.class.getMethod("main", String[].class);methods.invoke(null, (Object) new String[] { "--input","data/train_10000.data", "--output", "web.mallet","--preserve-case", "--keep-sequence" });} catch (Exception e) {e.printStackTrace();}}
