Hi friend,
A constant value in a program is denoted by a literal.
Literals represent numerical (integer or floating-point), character, boolean or string values.
Example of literals:
Integer literals:
1 2 4
Floating-point literals:
.66 0.3 6.14
Character literals:
'(' 'Z' 'k' '{'
Boolean literals:(predefined values)
true false
String literals:
"Hello" "abc" "gfh" "dfg"
Three reserved identifiers are used as predefined literals:
true and false representing boolean values.
null representing the null reference.

Hi,
In programming, a value written exactly as it's meant to be interpreted. In contrast, a variable is a name that can represent different values during the execution of the program. And a constant is a name that represents the same value throughout a program. But a literal is not a name -- it is the value itself.
A literal can be a number, a character, or a string. For example, in the expression,
x = 3
x is a variable, and 3 is a literal.
Thanks.
