Java literals are fixed, direct representations of data values written directly within code, serving as fundamental building blocks for representing numbers, characters, text, and special states.

Welcome back to CodeChef. Did you know
that every value in your Java program
has a literal representation? Today,
we'll explore Java literal. The way you
write numbers, characters, text, and
special values directly in your code to
represent data. Think of literal like
labels on ingredients in a recipe. When
you see two cups of flour or 1 teaspoon
of salt, those numbers and measurements
are fixed values you don't need to calculate.
calculate.
Similarly, literals are the fixed values
you type directly into your program,
like the number 42 or the word hello. In
Java, a literal is a fixed value written
directly in the code. Examples include
integers like 10, floatingoint numbers
like 3.14, characters like a, strings
like Java rocks, and the special null
literal indicating no value. Here's a
simple Java example.
Each value on the right side is a
literal, a fixed direct representation
of data. When we run this program, the
output will be quick facts about
literals. Integer literal are written
without quotes like 100. Floating point
literal use an f or f suffix eg 3.14f.
Character literal are enclosed in single
quotes eg z. String literal are in
double quotes eg hello. The null lit
indicates an empty reference. Now it's
your turn. Try this beginnerfriendly
problem on code chef using literal.
Write a program that declares variables
using int, float, char, string, and null
literal and prints their values.
Today you learned literal are fixed
values directly written in your code.
Java supports int, float, char, string,
and null literal. Use correct syntax,
quotes for chars and strings, fsuffix
for floats, and null for no value. Code
