When to use Java BigInteger
Java BigInteger class is used to perform arithmetic operation or holding Numbers large enough that Integer cannot hold. In fact BigInteger does not have any limit on the numerical value that it can represent.
java.math.BigInteger
Integer Max and Min value
In Java Integer can hold between 2147483647 and -2147483648. This is denoted by Integer.MAX_VALUE and Integer.MIN_VALUE
Print Value of Integer Max and Min
Print max and min value
System.out.println(Integer.MAX_VALUE); //2147483647
System.out.println(Integer.MIN_VALUE); //-2147483648When we have numbers that cannot fit in the Integer range we can use BigInteger class. Also this Class provides a lot of methods to carry out different mathematical operations such as
add,
subtract,
divide,
multiply and many more
BigInteger Example
BigInteger a = BigInteger.valueOf(15);
BigInteger b = BigInteger.ONE;
BigInteger result = a.add(b);
System.out.println("Addition of a,b = " + result);
result = a.subtract(b);
System.out.println("Subtration of a,b = " + result);
result = a.divide(b);
System.out.println("Division of a,b = " + result);
result = a.multiply(b);
System.out.println("Multipllication of a,b = " + result);
