A primitive variable can be one of eight types: char, boolean, byte, short, int, long, double, or float. Once a primitive has been declared, its primitive type can never change, although in most cases its value can change.

The range for these floating point numbers is difficult to determine. Booleans and char type variables do not have a range. Booleans can be either true or false and chars can be only one character in size Ex: "A" or "B" etc

What is type safety in java?
Type safety is the degree to which the language prevents you from making typing errors. That is: assigning values of one type to variables of another type. For example, in Java: int i; String s = "Not an integer"; i = s; is a type error as you are trying to assign a value of type String to a variable of type int. Java is moderately type safe as it will allow you to "type-cast" (automatically convert types) for some combinations but will give a compiler error for others.
Use of valueOf function in java?
The valueOf functions are used in the Java wrapper classes to convert between types. Common uses are converting a number to a String or vice versa. You are encouraged to use these functions instead of creating a new object from a constructor because of the way Java caches values. A call to valueOf will give you the same result as creating a new object, but it may be more efficient if you're creating the same values multiple times.
