+throws关键字
+    throws:声明一个异常，提醒方法的调用者，该方法可能会抛出某些异常，但是也有可能不抛出异常
+    throw:真的抛出了一个真正的异常
+
+    throws关键字的语法格式：
+    方法修饰符 返回值类型 方法名(参数列表) throws 异常名,异常名...{
+        方法体
+    }
+
+    注意点：
+    1.方法中如果抛出一个编译时异常，一定要处理(try-catch)或者声明出去
+    2.如果调用了一个声明了编译时异常的方法，那么也一定要处理(try-catch)或者声明出去
+    3.如果方法中没有异常出现，我们也是可以声明
