The switch statement evaluates an expression. The value of the expression is then compared with the values of each case in the structure. If there is a match, the associated block of code is executed. The switch statement is often used together with a break or a default keyword (or both)...
通常而言大家普遍的认知里switch case的效率高于if else。根据我的理解而言switch的查找类似于二叉树,if则是线性查找。按照此逻辑推理对于对比条件数目大于3时switch更优,并且对比条件数目越多时switch的优势越为明显。 一、测试目的 最近与开发同学对于前面提到的性能问题,有着各自不同的见解,为证明我的观点,现设计如...
