Java int is Primitive Data Type, and Integer is a wrapper class. In Java, all data types variables must first be declared before they can be used.
If you think about Java int is the same as a number, you might be right or wrong because in programming it about memory allocation of particular variables. So Number further has divided into data types like int, long, double float, etc.

Where Java int default values are “0“. and the size is 16 bits.
Java int range
It has a minimum value of –2,147,483,648 and a maximum value of 2,147,483,647 (inclusive).
Java int example
Here is a simple example of how to create an int variable in Java and print the value.
class Hello { public static void main(String args[]) { int a = 546; System.out.println(a); } }
Output: 546
How to do check number is equal or not?
Here is code to check whether 2 numbers (int) are equal or not. If equal then the output will be true else false.
class Hello { public static void main(String args[]) { int a = 546; int b =78; System.out.println( a == b); } }
Output: false
QA: Is it possible to assign the value in int beyond its maxed values? And What if integer beyond its max value?
It’s not possible, will throw an error: Error:(4, 17) java: integer number too large
