What is the maximum value for int in Java?
-2147483648 to 2147483647
The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Why those numbers? Integers in Java are represented in 2’s complement binary and each integer gets 32 bits of space. In 32 bits of space with one bit used to represent the sign you can represent that many values.
Why is 2147483647 the max int value?
(The non-negative ones include 0.) So the highest number we can store in 32 bits when we decide to store the numbers this way is : 2,147,483,647. It is so because we have to represent integer values( two set of the same numbers, one +ve and other -ve). = is 2^n = 2^3 = 8.

What is maximum value of Int32?
2,147,483,647
Int32 Member Details. Represents the largest possible value of an Int32. This field is constant. The value of this constant is 2,147,483,647; that is, hexadecimal 0x7FFFFFFF.
How do you find the max value in Java?
Example 1
- public class IntegerMaxExample1 {
- public static void main(String[] args) {
- // get two integer numbers.
- int x = 5485;
- int y = 3242;
- // print the larger number between x and y.
- System.out.println(“Math.max(” + x + “,” + y + “)=” + Math.max(x, y));
- }

What is long max value in Java?
9,223,372,036,854,775,807
From Oracle: long: The long data type is a 64-bit signed two’s complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive).
What happens when int exceeds max value?
In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value.
