Is there a way in Java to find the name of the variable passed to the function?

I have a Java function called testfornull

public static void testForNull(Object obj)
    {
     if (obj == null)
      {
        System.out.println("Object is null");
      }
    }

I use it to test multiple objects to make sure they are not empty However, I cannot tell the name of the variable in this way

For example, if I say

testForNull(x);
    testForNull(y);
    testForNull(z);

I don't know which of the three lines causes the output of "object is null" Of course, I can simply add another parameter to the function and have something similar

testForNull(x,"x");
    testForNull(y,"y");
    testForNull(z,"z");

But I wonder if I can infer the name of the variable instead of passing it explicitly thank you.

Solution

Consider that the parameter may not be a variable (so it will not have a name):

testForNull(x != y);
