java.math.BigInteger intValue()
Description
For reference the byte range is from2147483647 to -2147483648 and these information is readily available through the Integer constants Integer.MIN_VALUE and Integer.MAX_VALUE.
Notes:
- This method is specified by intValue in class Number.
Method Syntax
public int intValue()
Method Argument
| Data Type | Parameter | Description |
|---|---|---|
| N/A | N/A | N/A |
Method Returns
The intValue() method returns this BigInteger converted to primitive int.
Compatibility
Requires Java 1.1 and up
Java BigInteger intValue() Example
Below is a java code demonstrates the use of intValue() method of BigInteger class. The example presented might be simple however it shows the behavior of the intValue() method.
package com.javatutorialhq.java.examples;
import java.math.BigInteger;
import java.util.Scanner;
/*
* A java example source code to demonstrate
* the use of intValue() method of BigInteger class
*/
public class BigIntegerIntValueExample {
public static void main(String[] args) {
// Declare and initialize our BigInteger values
BigInteger val1 = new BigInteger("12");
BigInteger val2 = new BigInteger("21474832647");
// get the int equivalent of each BigInteger
int intVal1 = val1.intValue();
int intVal2 = val2.intValue();
// print the operation
System.out.println("val1 in int is "+intVal1);
System.out.println("val2 in int is "+intVal2);
}
}
This example is a lot simpler than it looks. We only initialize two BigInteger, one is certainly within range and the other one is outside the range of int. We have printed out the result of conversion from BigInteger to int.
Sample Output
Below is the sample output when you run the above example.
