考虑到你有这样的代码:

doSomething() // this method may throw a checked a exception
//do some assignements calculations
doAnotherThing() //this method may also throw the same type of checked exception
//more calls to methods and calculations, all throwing the same kind of exceptions.

现在我知道,实际上在构造异常时会出现性能损失,特别是展开堆栈.我还阅读了几篇文章,指出在输入try/catch块时会有轻微的性能损失,但这些文章似乎都没有结论.

我的问题是,是否建议将try catch中的行保持最小？,即只在try子句中包含可以实际抛出正在捕获的异常的行.try子句中的代码运行速度较慢或导致性能下降吗？

但考虑到这一点,更重要的是最佳实践/更易读的解决方案:

try {
    doSomething() // this method may throw a checked a exception
//do some assignements calculations
doAnotherThing() //this method may also throw the same type of checked exception
//more calls to methods and calculations, all throwing …
