I was asked in an interview as to why the variable names can't start with a numerical value ? To be more precise the interviewer wanted to know the lexical / compilation problems associated with declaring a variable name that starts with a numerical ?

Answers will be appreciated.

Welcome to JavaRanch

think about this:

int 2L = 100;
long value = 2L;//what is the value of value variable?


int 4L = 200;

I agree. Here's the link:
