In school math, we usually follow a procedure to find all factors for any given positive integer number. This process is called factorization, and it takes quite a lot of calculation depending on how big the integer number is. With the Java programming environment, let’s create a simple program to do the same job for us. We’d like to write code to find all factors of any positive integer. When a user inputs “10,” the program is supposed to output: 1, 2, 5, and 10. As the first step, we need to define the procedure and then implement it by Java code.
