Introduction To Java
JAVA was developed by James Gosling at Sun Microsystems Inc in the year 1991, later acquired by Oracle Corporation. It is a simple programming language. Java makes writing, compiling, and debugging programming easy. It helps to create reusable code and modular programs.
Java is a class-based, object-oriented programming language and is designed to have as few implementation dependencies as possible. A general-purpose programming language made for developers to write once run anywhere that is compiled Java code can run on all platforms that support Java. Java applications are compiled to byte code that can run on any Java Virtual Machine. The syntax of Java is similar to c/c++.

Java BigInteger – Hacker Rank Solution
Problem :
In this problem, you have to add and multiply huge numbers! These numbers are so big that you can’t contain them in any ordinary data types like a long integer. Use the power of Java’s BigInteger class and solve this problem.
Input Format
There will be two lines containing two numbers, a and b.
Constraints
a and b are non-negative integers and can have maximum 200 digits.
Output Format
Output two lines. The first line should contain a+b, and the second line should contain a*b. Don’t print any leading zeros.
Sample Input
1234 20
Sample Output
1254 24680
Explanation
1234+20 = 1254 1234*20 = 24680
