multi-catch属于JDK1.7之后出现的，举例如下：


class FactoryTest {
  public static Fruits getInstance(String className){
    Fruits fruits=null;
    try {
      fruits=(Fruits)Class.forName(className).newInstance();
    } catch (InstantiationException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (IllegalAccessException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    } catch (ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    return fruits;
  }
}
===============================================
class FactoryTest {
  public static Fruits getInstance(String className){
    Fruits fruits=null;
    try {
      fruits=(Fruits)Class.forName(className).newInstance();
    } catch (InstantiationException | IllegalAccessException | ClassNotFoundException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
    return fruits;
  }
}
