java判断Long类型的方法和实例代码

public class HelloWorld {

  public static void main(String[] args) {

    Boolean res = getType(1232343234L);

    if(res) {

      System.out.println("是Long类型");

    }else{

      System.out.println("不是Long类型");

    }

  }

   

  public static Boolean getType(Object o) {

    String type = o.getClass().toString();

    System.out.println(type);

    type = type.substring(type.lastIndexOf('.') + 1, type.length());

    if("Long".equals(type)) {

      return true;

    }

    return false;

  }

}
