java.math.biginteger cannot be cast to java.lang.long
// BigInteger can be bigger than Long. If so, then the ".longValue()" will return an exception.
public static void main(String[] args) { // Program start method.
BigInteger bigInteger = new BigInteger(Long.MAX_VALUE + ""); // Create the BigInteger.
System.out.println("LongValue: " + bigInteger.longValue()); // Get the value in Long form.
}java int to biginteger
// Primitive int
int myInt = 10
BigInteger bigInt = BigInteger.valueOf(myInt);
// Integer object
Integer integer = Integer.valueOf(myInt);
BigInteger bigInt = BigInteger.valueOf(myInteger.intValue());
bigInt = BigInteger.valueOf(myInteger); // works tooCopyright © 2021 Codeinu
