Data Types In Java

- Java is strongly typed language. This means that every variable must have a declared type. There are eight primitive types in Java:
  + Four of them are integer types.
  + Two are floating-point number types.
  + One is the character type char - used for code units in the Unicode encoding scheme.
  + One is a boolean type for truth values.
- Java has an arbitrary-precision arithmetic package. However, "big numbers", as they are called, are Java object and not a new Java type.
