Hi All,

Could you please let me know which are the best practice to check null in List, Map, Set to avoid nullpointer exception....

For String fields, you should use '' check and for number/Id fields, you should use NULL check.

In some cases, you might face some weird issues with such comparisons, the workaround then is to check for both :D

For Collections I use size() method.

I have a custom function that basically calls both ISNULL & ISBLANK

you can put a If check. like this if(list.size()>0){
...
}
