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 ...

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 ... Read More

Let us see an example first to understand how an integer looks with left padding −888 //left padding with spaces 0000000999 //left padding with 7 zerosLet us see an example to left pad a number with zero −Example Live Demopublic class Demo {    public static void main(String[] args) {   ...

The following is an example −Example Live Demopublic class Demo {    public static void main(String[] args) {       String str = "laptop";       System.out.println("Original String = " +str);       // letter one       String strOne = str.substring(0, 1).toUpperCase();       // ... Read More

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.Firstly, set a long value −Long l = 198L;Now, create a new object ...

The java.math.BigInteger class provides operations analogues to all of Java's primitive integer operators and for all relevant methods from java.lang.Math.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 ... Read More

Use the BigInteger subtract() method in Java to Subtract one BigInteger from another.First, let us create some objects −BigInteger one, two, three; one = new BigInteger("200"); two = new BigInteger("150");Subtract the above and assign it to the third object −three = one.subtract(two);The following is an example −Example Live Demoimport java.math.*; public ... Read More

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 ...

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. ...

To compare enumeration values, use the equals() method.Our Devices enum is having some objects with values assigned to them.Devices d1, d2, d3; d1 = Devices.LAPTOP; d2 = Devices.LAPTOP; d3 = Devices.TABLET;Let us compare them −if(d3.equals(Devices.TABLET)) System.out.println("Devices are same."); else System.out.println("Devices are different.");The following is an example −Example Live Demopublic class Demo ...
