Java int variables store integers in the range of -2,147,483,648 through 2,147,483,647 inclusive. All int variables have operations similar to double (+, *, -, =), but some differences do exist, and there are times when int is the correct choice over double. For example, a fractional remainder cannot be stored in an int.

int inum = Integer.parseInt( argument1 ); // inum = 123. double dnum = Double.parseDouble( argument2 ); // dnum = 123.45. Converting Numbers to Strings. Sometimes you may want to convert a number to a string because you need to operate on its value in string form. You can convert a number to a string in one of the following ways:

Integer >() ; Storing a Primitive Type Value in an ArrayList. Since Java 1.5 (aka: “Java 5”), we have been able to store primitive type values in ArrayLists simply by passing them as arguments to the add() and set() methods. For example, here is a loop that stores the . int. s 1 through 10 in elements 0 through 9 of an ArrayList:
