The following is our string −String str = "Amit";Now take a StringBuilder object −StringBuilder strBuilder = new StringBuilder();Set the character you want to pad with a string −Character ch = '^';Perform left padding and extend the string length to 5 (one for the additional character). The character that will be padded comes on the left −while (strBuilder.length() + str.length() < 5) { strBuilder.append(ch); }The following is an example −Example Live Demopublic class Demo {    public static void main(String[] args) {       String str = "Amit";       Character ch = '^';       StringBuilder strBuilder = ...

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 complemented and AND'ed with this BigInteger.The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two, three;       one = new BigInteger("12");       two = new BigInteger("6");       three = ...

TheBigInteger.or(BigInteger val) returns a BigInteger whose value is (this | val). This method returns a negative BigInteger if and only if either this or val is negative.Here, “val” is the value to be OR'ed with this BigInteger.The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two, three;       one = new BigInteger("6");       two = one.or(one);       System.out.println("Result (or operation): " +two);    } }OutputResult (or operation): 6Let us see another example −Example Live Demoimport java.math.*; public class Demo { ...

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;       one = new BigInteger("6");       two = one.not();       System.out.println("Result (not operation): " +two);    } }OutputResult (not operation): -7Let us see another example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger bi1, bi2, ...

The java.math.BigInteger.and(BigInteger val) returns a BigInteger whose value is (this & val). This method returns a negative BigInteger if and only if this and val are both negative. Here, “val” is the value to be AND'ed with this BigInteger.First, create BigInteger objects −BigInteger one, two, three; one = new BigInteger("12"); two = new BigInteger("6");Perform AND operation on first and second object −three = one.and(two);The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two, three;       one = new BigInteger("12");       two ...

The java.math.BigInteger.xor(BigInteger val) returns a BigInteger whose value is (this ^ val). This method returns a negative BigInteger if and only if exactly one of this and val are negative. Here, “val” is the value to be XOR'ed with this BigInteger.Firstly, create two BigInteger objects −one = new BigInteger("6"); two = new BigInteger("-5");Now, perform XOR −three = one.xor(two);The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one, two, three;       one = new BigInteger("6");       two = new BigInteger("-5");       ...

To shift right in a BigInteger, use the shiftRight() method.The java.math.BigInteger.shiftRight(int n) returns a BigInteger whose value is (this >> n). Sign extension is performed. The shift distance, n, may be negative, in which case this method performs a left shift. It computes floor(this / 2n).The following is an example −Example Live Demoimport java.math.*; public class Demo {    public static void main(String[] args) {       BigInteger one;       one = new BigInteger("25");       one = one.shiftRight(3);       System.out.println("Result: " +one);    } }OutputResult: 3

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.Let us work with the testBit() method in Java to perform Bitwise operation. The java.math.BigInteger.testBit(int n) returns true if and only if the designated bit is set −The following is an example −Example Live Demoimport java.math.*; public class BigIntegerDemo {    public static void main(String[] args) {       BigInteger one;       Boolean two;       one = new BigInteger("5"); ...

Use the BigInteger pow() method in Java to calculate the power on a BigInteger.First, let us create some objects.BigInteger one, two; one = new BigInteger("5");Perform the power operation and assign it to the second object −// power operation two = one.pow(3);The following is an example −Example Live Demoimport java.math.*; public class BigIntegerDemo {    public static void main(String[] args) {       BigInteger one, two;       one = new BigInteger("5");       System.out.println("Actual Value: " +one);       // power operation       two = one.pow(3);       System.out.println("Result: " +two);    } }OutputActual Value: 5 Negated Value: 125

Use the BigInteger negate() method in Java to negate a BigInteger.First, let us create an object −BigInteger one, two; one = new BigInteger("200");Negate the above and assign it to the second object −two = one.negate();The following is an example −Example Live Demoimport java.math.*; public class BigIntegerDemo {    public static void main(String[] args) {       BigInteger one, two;       one = new BigInteger("200");       System.out.println("Actual Value: " +one);       // negate       two = one.negate();       System.out.println("Negated Value: " +two);    } }OutputActual Value: 200 Negated Value: -200
