这个也没有解决说如果excel没有这个类还能运行啊
public class test {
public static void main(String[] args) {
// TODO Auto-generated method stub
if("word".equals(args[0])){
Class c;
try {
c = Class.forName(args[0]);
word w=(word)c.newInstance();
w.start();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if("excel".equals(args[0])){
Class c;
try {
c = Class.forName(args[0]);
excel e=(excel)c.newInstance();
e.start();
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}如果我没有excel的类，在编译时还是会报错，并不能实现这个功能，
难道说只能用接口，那样只能体现接口的作用
