关于 for 循环中，括号里的函数调用

This topic created in 3150 days ago, the information mentioned may be changed or developed.

下面两种写法，哪种好？其实我的意思是第一种中 jvm 会自动优化，使得每次循环不用调用 someObject.getStrList()吗？还是每次循环都要调用一下 someObject.getStrList()？

for(String elem: someObject.getStrList()){
    ...
}

List<String> strList = someObject.getStrList();

for(String elem: strList){
    ...
}
