In Java, the int data type is a 32-bit signed integer. Its range is defined by the constants Integer.MIN_VALUE and Integer.MAX_VALUE in the java.lang package. The maximum value an int can hold is 2,147,483,647, which is equivalent to 2^31 - 1.
To determine how many millions this value represents, divide it by 1,000,000:
int maxInt = Integer.MAX_VALUE;System.out.println("Maximum value of int in millions: " + (maxInt / 1_000_000));Kopiert!✕KopierenOutput:
Maximum value of int in millions: 2147Kopiert!✕KopierenThus, a Java int can hold up to 2,147 million.
Important Considerations
If you attempt to store a value larger than Integer.MAX_VALUE in an int, it will cause an overflow, resulting in incorrect values. For example:
int overflowExample = Integer.MAX_VALUE + 1;System.out.println(overflowExample); // Output: -2147483648Kopiert!✕KopierenFor numbers larger than Integer.MAX_VALUE, consider using the long data type (64-bit) or the BigInteger class for arbitrarily large integers.
