Java try/catch 性能，是否建议将 try 子句中的内容保持在最低限度？

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.

现在我知道了，实际上在构造异常（特别是展开堆栈）时会受到性能影响。我还阅读了几篇文章，指出在进入尝试/捕获块时性能受到轻微影响，但似乎没有一篇文章得出任何结论。

我的问题是，是否建议将 try catch 内的行保持在最低限度？，即只在 try 子句中包含可以实际抛出您正在捕获的异常的行。try 子句中的代码是否运行速度较慢或导致任何性能下降？

但更重要的是，考虑这样做的最佳实践/更具可读性的解决方案是什么：

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 the same kind of exceptions.
}
catch (MyCheckedException e) {
   //handle it
}

或：

try {
    doSomething() // this method may throw a checked a exception
}
catch (MyCheckedException e) {
   //Store my exception in a Map (this is all running in a loop and I want it to   continue running, but I also want to know which loops didn't complete and why)
   continue;     
} 
 //do some assignements calculations
try {
    doAnotherThing() // this method may throw a checked a exception
}
catch (MyCheckedException e) {
    //Store my exception in a Map (this is all running in a loop and I want it to   continue running, but I also want to know which loops didn't complete and why)
   continue;
} 

这是考虑到您将以完全相同的方式处理所有这些已检查的异常。
