Explanation:
The description of the above code can be given as:
- In the above java programming code firstly we define a class that is "Main". In this class we define a main method in the main method we define a variables that is "n" in this variable we assign a positive value. The we define another integer variable that is i,j this variable is used in the loop.
- Then we define a loop. for prints asterisks values in reverse triangle, we nested looping concept. In nested looping, we use in loop in this loop we use the i and j variables that print the asterisks value.
