String hello = "hello"; //characters
short one = 12;//shorter integers
int two = 2000; //complete integer up too 32 bits
long number = 2000000; //complete integer up to 64 bits
float decimal = 1.512 //up to 7 decimal digits
double million = 1.387892847395 //up tp 16 decmial digits

int a = 10, b = 10;  // Example of initialization
byte B = 22;         // initializes a byte type variable B.
double pi = 3.14159; // declares and assigns a value of PI.
char a = 'a';        // the char variable a iis initialized with value 'a'
