Here, we are going to learn how to convert double primitive type into int and Double object into int. The Integer class in Java belongs to the java.lang package, which means any class is free to use the methods in this class without importing any package. It implicitly extends the class Number, which is a direct subclass of Object. Number is an abstract class and acts as a superclass to BigInteger, BigDecimal, and most wrapper classes — Double, Integer, Short, Byte, Float and Long.
