Firstly, take two BigInteger objects and set values.BigInteger one, two; one = new BigInteger("99"); two = new BigInteger("978");Now, parse BigInteger object “two” into Binary.two = new BigInteger("1111010010", 2); String str = two.toString(2);Above, we have used the following constructor. Here, radix is set as 2 for Binary for both BigInteger constructor ... Read More

Set a BigInteger object.BigInteger one;Now, create a ByteArray.byte byteArr[] = new byte[] { 0x1, 0x00, 0x00 }; one = new BigInteger(byteArr);For Binary, we have used 2 as the toString() method parameter.String strResult = one.toString(2);The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] ...

The BigInteger.not() method returns a BigInteger whose value is (~this). This method returns a negative value if and only if this BigInteger is non-negative.The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two, three;   ... Read More

TheBigInteger.andNot(BigInteger val) returns a BigInteger whose value is (this & ~val). This method, which is equivalent to and(val.not()), is provided as a convenience for masking operations. This method returns a negative BigInteger if and only if this is negative and val is positive. Here, “val” is the value to be ... Read More

Let us see an example first to understand how a string looks with left padding −demotext //left padding with spaces 0000000demotext //left padding with 7 zerosThe following is our string −String str = "Jack";Now take a StringBuilder object −StringBuilder strBuilder = new StringBuilder();Perform left padding and extend the string length. ...

The following is our string −String str = "Tim";Now take a StringBuilder object −StringBuilder strBuilder = new StringBuilder();Perform left padding and extend the string length. We have set it till 20, that would include the current string as well. The zeros that will be padded comes on the left. Append ... Read More

BigInteger class provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.Let’s say the following is our byte array −byte[] arr = new byte[] { 0x1, 0x00, 0x00 };We will now convert them to BigInteger −BigInteger bInteger = new BigInteger(arr);The following ...

BigInteger class is used for big integer calculations which are outside the limit of the primitive data types. It provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations.To multiply one BigInteger to another, use the BigInteger multiply() method.First, let us ...
