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));
- }
How do you declare a 64 bit integer in Java?
If you want a 64-bit integer, use a long , which is always 64 bits = 8 bytes. You need to mark the literal as a long literal by adding an L at the end: 9223372036854775806L .

How does Java handle integer overflow?
4. Handling Underflow and Overflow of Integer Data Types
- 4.1. Use a Different Data Type. If we want to allow values larger than 2147483647 (or smaller than -2147483648), we can simply use the long data type or a BigInteger instead.
- 4.2. Throw an Exception.
- 4.3. Before Java 8.
