{
public static void main(String[] args)
{ // write your code here
System.out.println("Helluo i am chetan bro word");

String name = null;
System.out.println(name);

int a = 45;
float b = 45.22f ;
boolean isadulat = false;
char grade = 'A';
System.out.println(grade);
System.out.println(a);
System.out.println(b);
System.out.println(isadulat);
/*rules for costructing variable in java;

can contain digit , underscore, dollar letter
names can beging with a letter

java is a case sative language which means that cheta and Cheta is another language

shoud not contain white spaces

you cannot use reversed name
u
shod beging letter dollar underscore



two types of data type

1 primitive short 4 bites double 8 types
2 unprimitive




*/byte u = 56;
double d= 45.9997777;
System.out.println(d);
System.out.println(56);


int num1 = 10 ,num2 =5;
System.out.println("value of num1+ value of num2");
System.out.println(num1+num2);

System.out.println("value of num1-value of num2");
System.out.println(num1-num2);

Answer 1

Answer:

{

public static void main(String[] args)

{ // write your code here

System.out.println("Helluo i am chetan bro word");

String name = null;

System.out.println(name);

int a = 45;

float b = 45.22f ;

boolean isadulat = false;

char grade = 'A';

System.out.println(grade);

System.out.println(a);

System.out.println(b);

System.out.println(isadulat);

/*rules for costructing variable in java;

u

shod beging letter dollar underscore
