Question

Identify the following as valid or invalid variable name:

1) 10code
2)Else
3)Employee
4)Abc
5)A.B.C

​

Answer 1

Answer:

1st one is valid but give a under score to so that it would look more readable results "10_code".

second one is not a variable it is a statement if you use it as a variable it will give us an error

3,4,5 are good variables but be careful in the case-sensitive languages that means we cannot use capital letters at starting to declare the variable

cation : don't use 5th variable name in Java because it analys as it is an data structure

thank you
