3、Call "remove()" on "requestContainer". 说明:防止内存泄露溢出,ThreadLocal字段【requestContainer】应该至少调用一次remove()方法。 // 解决方案:定义删除方法 public void removeRequest() { requestContainer.remove(); } 4、Use try-with-resources or close this "FileInputStream" in a "finally" claus...
1.Replace the type specification in this constructor call with the diamond operator ("<>"). Java 7引入了菱形运算符(<>)来减少泛型代码的冗长。 例如,您现在可以使用<>简化构造函数声明,而不必在其声明及其构造函数中声明List的类型,编译器将推断该类型。如下: 2.Add a default case to this switch swa...

2.Add a default case to this switch swatch 中没有default,也没有break;虽然上面的代码不要break也不会有什么问题。但是万一哪天变了,不是return 就很容易出错了吧。 3.Remove this empty statement. 两个分号,代码中有很多地方有这种情况感觉,删掉多余的。

30、Move the array designator from the variable to the type. 问题分析: 数组指示符应始终位于类型上,以提高代码可读性。否则,开发人员必须同时查看类型和变量名,以了解变量是否为数组。 解决: 将[]从变量名后面放到变量名前面。 31、Replace the type specification in this constructor call with the diamond ...
