variables java

/* Depending on what variables you want to declare */
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
Bool condition = true; // true or false
char a = "a"; // unicode character
