Q:

Why is 2,147,483,647 the max int value?

Can someone provide me with a detailed explanation of why 2,147,483,647 is the maximum integer value in Java?

A:

Because the total value an int can hold in Java is 2^32 (2 to the power of 32, in other words a 32 bit number), for which half is reserved for negative numbers and half for positive numbers.
