Java Copy In this example, we have a switch statement that checks the value of the variableday. Depending on the value, it executes a different code block. Ifdayis 1, it prints ‘Monday’. Ifdayis 2, it prints ‘Tuesday’. In our case,dayis 3, so none of the cases match and not...
java switch与if性能 java中if和switch的区别,通常而言大家普遍的认知里switchcase的效率高于ifelse。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。
