“Handling Large Numbers in Java: Choosing the Right Data Types”

In Java, there are several data types that can store large numbers:

long: This is a primitive data type that can store a 64-bit signed integer. The maximum value it can store is 9,223,372,036,854,775,807.

BigInteger: This class can store any integer as large as the RAM on your computer can hold. It’s not mapped to a primitive type, so it can handle values much larger than long. Here’s an example of how to use it:

BigInteger big1 = new BigInteger("1234567856656567242177779"); 
BigInteger big2 = new BigInteger("12345565678566567131275737372777569"); 
BigInteger bigSum = big1.add(big2); System.out.println(bigSum);

BigDecimal: This class is similar to BigInteger, but it’s used for decimal numbers. It’s excellent for calculations that require a high degree of precision. Here’s an example of how to use it:

BigDecimal bd = new BigDecimal("123234545.4767"); 
BigDecimal displayVal = bd.setScale(2, RoundingMode.HALF_EVEN); 
System.out.println(displayVal.doubleValue());

These classes (BigInteger and BigDecimal) are slower than primitive types, so they should only be used when you need to handle very large numbers.
