BigInteger Class valueOf() method

• valueOf() method is available in java.math package.
• valueOf() method is used to represent the given long value into a BigInteger.
• valueOf() method is a static method, it is accessible with the class name and if we try to access the method with the class object then we will not get an error.
• valueOf() method does not throw an exception at the time of representing the long value.

Syntax:

    public BigInteger valueOf(long val);

Parameter(s):

• long val – represents the long value to be returned in terms of BigInteger.

Return value:

The return type of this method is BigInteger, it returns BigInteger of the given long value.

Example:

// Java program to demonstrate the example 
// of BigInteger valueOf(long val) method of BigInteger

import java.math.*;

public class ValueOfOfBI {
    public static void main(String args[]) {
        // Instantiates a variable l_val
        long l_val = 125487312456l;

        // Here, this method valueOf(long) is used
        // to convert the given long value into
        // a BigInteger and store it in a variable
        // named value_of
        BigInteger value_of = BigInteger.valueOf(l_val);

        System.out.println("l_val: " + l_val);
        System.out.println("valueOf(long): ");

        // Display value_of
        System.out.println("BigInteger.valueOf(l_val): " + value_of);
    }
}

Output

l_val: 125487312456
valueOf(long): 
BigInteger.valueOf(l_val): 125487312456
