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. As the java.math package is not automatically made available you may have to import java.math.BigInteger before you can use the simple class nam...

You can compare BigIntegers same as you compare String or other objects in Java. For example: BigInteger one = BigInteger.valueOf(1); BigInteger two = BigInteger.valueOf(2); if(one.equals(two)){ System.out.println("Equal"); } else{ System.out.println("Not Equal"...

BigInteger is in an immutable object, so you need to assign the results of any mathematical operation, to a new BigInteger instance. Addition: 10 + 10 = 20 BigInteger value1 = new BigInteger("10"); BigInteger value2 = new BigInteger("10"); BigInteger sum = value1.add(value...

BigInteger supports the binary logic operations that are available to Number types as well. As with all operations they are implemented by calling a method. Binary Or: BigInteger val1 = new BigInteger("10"); BigInteger val2 = new BigInteger("9"); val1.or(val2); Output:...

The BigInteger class has a constructor dedicated to generate random BigIntegers, given an instance of java.util.Random and an int that specifies how many bits will the BigInteger have. Its usage is quite simple - when you call the constructor BigInteger(int, Random) like this: BigInteger randomBigI...
