Let us apply the following operations on BigInteger using the in-built methods in Java.Addition: add() method Subtraction: subtract() method Multiplication: multiply() method Division: divide() methodLet us create three BigInteger objects.BigInteger one = new BigInteger("98765432123456789"); BigInteger two = new BigInteger("94353687526754387"); BigInteger three = new BigInteger("96489687526737667");Apply mathematical operations on them.one = one.add(two); System.out.println("Addition Operation = " + one); one = one.multiply(two); System.out.println("Multiplication Operation = " + one);The following is an example −Example Live Demoimport java.math.BigInteger; public class Main { public static void main(String[] args) { BigInteger one = new BigInteger("98765432123456789"); ...

Let us set a radix here as.// radix int r = 32;Include the radix here as a BigInteger constructor.BigInteger one = new BigInteger("vv", r);Now get its string representation −String strResult = one.toString(radix);The following is an example −Example Live Demoimport java.math.*; public class Demo { public static void main(String[] args) { // radix int r = 32; BigInteger one = new BigInteger("vv", r); String strResult = one.toString(r); System.out.println(strResult); } }Outputvv

Set a BigInteger object.BigInteger one;Now, create a ByteArray −byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);For Decimal, we have used toString() method without any parameter value.String strResult = one.toString();The following is an example −Example Live Demoimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one; // ByteArray byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr); // Decimal String strResult = one.toString(); System.out.println("ByteArray to Decimal = "+strResult); } }OutputByteArray to Decimal = 65536

Set a BigInteger object.BigInteger one;Now, create a ByteArray.byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);For Octal, we have used 8 as the toString() method parameter.String strResult = one.toString(8);The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one;       // ByteArray       byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 };       one = new BigInteger(byteArr);       // Octal       String strResult = one.toString(8);       System.out.println("ByteArray to Octal = "+strResult);    } }OutputByteArray to Octal = 200000

Firstly, take two BigInteger objects and set values.BigInteger one, two; one = new BigInteger("99");Now, parse BigInteger object “two” into Octal.two = new BigInteger("1100", 8); String str = two.toString(8);Above, we have used the following constructor. Here, radix is set as 8 for Octal. for both BigInteger constructor and toString() method.BigInteger(String val, int radix)This constructor is used to translate the String representation of a BigInteger in the specified radix into a BigInteger.The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two;       one = new ...
