Reports local variable of wrapper type though all usages allowed to be primitive and count of unnecessary boxing/unboxing operations reduces
报告包装器类型的局部变量,尽管所有使用情况都允许是原始用法,并且不必要的装箱/拆箱操作的次数减少了
 
这个警告是说,尽量使用基本数据类型,这样就能减少装箱/拆箱操作了。
类似的例子:

......Boolean hs=false; for(var it:collect){ if(it.getYear==2020){ hs=true; ..... } } if(!hs){ ...... } .......

改成基本数据类型就行了,比如int
......int hs=0; for(var it:collect){ if(it.getYear==2020){ hs=1; ..... } } if(hs==0){ ...... } .......
