Explanation:

In the above java program code firstly a class "data" is defined, inside this class the main method is defined in which an integer variable userNum is defined that holds a value that is "4".

• In this method, a for loop is declare that uses variable userNum which starts from 1 and ends with a given value that is equal to 4.

• Inside a for loop, the print function is used that print userNum variable each values in the newline.
