How to check many variables for null?

Question

Java

Perhaps there is some kind of function that if at least one null element returned false
Or if there is at least one element in the array, it did a coexisting check.
Interested in how to do this in C # and Java.

Answer 1

In principle, you can do the check yourself:

bool Check<T>(params T[] values)
        {
            return values.All(val => val != null);
        }

Answer 2

Where are the variables? In a class, in an array, in a struct?

Answer 3

Alternatively, you can grab it already during execution -

try{
         //your code here 
}
catch(NullPointerException e)
{
         e.printStackTrace();
}
