Not entirely sure what integer means in Java. I have a vague description to fit to it but AGH ITS BUGGING ME.

Question

Such as: int var = 66
Could someone provide with a detailed description that I can run off of? The Java tutorial either never told me, or I didn't notice it.

Answer 1

An integer in programming is a data type used to hold a value of a whole number (such as 2, 56, or -51). In the example you provided, you created a variable with type int named var, which was given an integer value to hold.

Thank you, Faisal and Jason!

Answer 3

By default, the int data type is a 32-bit signed two's complement integer, which has a minimum value of -2^31 and a maximum value of 2^31.

Basically whole numbers between -2 billion and positive 2 billion
