Answer 6

may be you got your answer..then also.,

=== means "identical to"
if both value and datatype are same then it gives 1 or true..otherwise 0 or false.

Answer 7

It checks the value and data type,
Int a=1
Int b=1
Char c='1'
Double d=1.0
a===b returns true
a===c returns false
a===d returns false

Answer 8

If you mean == it means if it is equal,
and = is to asign it.
So if you write if(a = b) it is like you are asigning b to a in the if statement, resulting in a syntax error

Answer 9

if im not mistaken it check if the type is the same.
int a = 1;
int b = 2;
char c = z;
c===b return false.
a===b return true.
