In this lecture we are discussing:
1)What is literal ?
2)difference ways of representation of integers using literal?
a)decimal
b)binary
c)octal
d)hexadecimal
3)underscore use as literal to separate digits
4)different literal use in real value

#1
literal is a source code representation of a fixed value.
e.g 2000l --- represent long type of integers, 20.5f --- represent float

#2
their are many ways to represent integer using literal:
a)decimal
-- int num=10; int num=10004;

b)binary
-- int num=0b1010; int num=0b101
-- here literal in binary must start with 0b or 0B.

c)octal
-- int num=0123;
-- literal in octal must start with 0.

d)hexadecimal
-- int num=0xA, int num=0x13B
-- iteral in hexadecimal must start with 0x or 0X

#3
Underscore use as literal to separate digit
-- int num=1_000_000; int num=3_45_78; int num=0b1010_1010;
-- float num=3.4_56f; double num=3.4_5;
-- underscore can be used between numbers to make it more readable

#4
different literal in real numbers
-- float num=4.55f;
-- 4.5f is a float literal and f is a suffix
-- double d=3.44e10; --meaning of 3.44e10 is 3.44x10^10

class HelloWorld {
public static void main(String[] args) {

char c = 'a';
c = c+1;
System.out.println(c);
}
}

Error: conversion from int to char
c = c+1;
