So here goes a java program to calculate factorial of 50 or 100 or other numbers: For ex. This is a guide to Factorial in Java. Factorial of a non-negative integer, is multiplication of all integers smaller than or equal to n. For example factorial of 6 is 6*5*4*3*2*1 which is 720. Code Explanation: Started with two variables “i” and “fact”, with value 1, then “number” with 5, which is our number to calculate the factorial. This technique should be used when the problem statement has 2 properties: Overlapping Subproblems- The term overlapping subproblems means that a subproblem might occur multiple times during the computation of the main problem. 1. = 4*3*2*1 = 24 5!

Write a Factorial Program in Java Programming Language using For Loop, While Loop, Functions, and Recursion. Java is a widely-used programming language, it comes with many features, in this article we learned about Factorial Calculations in Java, which is a tiny aspect. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution. Went into For Loop, kept increasing the value of i until we matched it with number, i.e. Code: Factorial of Number
