Java Integer Class
The Integer class wraps a value of the primitive type int in an object. An object of type Integer contains a single field whose type is int. In addition, this class provides several methods for converting an int to a String and a String to an int, as well as other constants and methods useful when dealing with an int. Since JDK1.0 See Also
Java Integer class provides several field constants that are as follows 1. static int MAX_VALUE It represents a constant that can hold the maximum value of int 2 31 - 1. 2. static int MIN_VALUE It represents a constant that can hold the minimum value of short -2 31. 3. static int SIZE It is the number of bits that are used to represent an int value in two's complement binary form.
From java.lang.Class.isPrimitive API. There are nine predefined Class objects to represent the eight primitive types and void. These are created by the Java Virtual Machine, and have the same names as the primitive types that they represent, namely boolean, byte, char, short, int, long, float, and double.

Java Integer Class. Last modified April 13, 2025 The java.lang.Integer class is a wrapper for the primitive int type. It provides methods for converting integer values to and from String, performing numerical operations, and working with useful constants.As part of Java's wrapper classes, Integer enables primitive values to be used as objects, making them compatible with collections and
Class Declaration. Following is the declaration for java.lang.Integer class . public final class Integer extends Number implements ComparableltIntegergt Field. Following are the fields for java.lang.Integer class . static int MAX_VALUE This is a constant holding the maximum value an int can have, 2 31-1.. static int MIN_VALUE This is a constant holding the minimum value an int can
Learn how to use the Integer class in Java, which wraps the int primitive type into an object. See how to create, compare, convert, and access Integer methods and fields with examples and explanations.
In Java, an immutable class is a class Integer, Byte, Long, Float, Double, Character, Boolean, and Short which once created then its body can not be changed and the same applies to immutable objects which once created cannot be changed. Now the question arises that we do need the help of wrapper c.
