    Try doing it one step at a time to print a box with dimensions width and height,
    Going back to post#10:

    Write a loop that loops height number of times.

    Now put the code for the loop in a main() method and put the main() method in a class. Compile it and execute it.
    Fix any errors. Post the full code here.
    When that's done, we'll move to the next step.

    What should I say in if statement for height?
    There isn't an if statement. The for loop controls the number of times the loop will execute.

    for (int j= 3; j <= height; j++) {
    			}
    			if (i%width) == 3)
                  System.out.print("#####");

    or

    for(int j = 1; j < height; j++){
    			}
    				if(height = 1){
    					System.out.print("#");
    					}
    				else (height = 5);{
    					System.out.print("#");
    					}
    				else
    					System.out.print(" ");
    					}

    Please reread the instructions. You are to write a small class with a main() method and a loop that loops height times.
    The program is going to be written one small, simple step at a time.


    If you'd rather do the assignment on your own, let me know and I'll leave.

    For testing you should write a simple program as described above to learn the techniques of writing loops and using if statements to control what is printed.
    When you have learned how to write the code to do that, you will have an easier time working on your assignment.

    Your choice on how to proceed:
    Try writing this simple program to learn how to do some programming
    or waiting until someone comes along to write the code for you.
    If you don't understand my answer, don't ignore it, ask a question.

    Start by writing the code that has been suggested in posts #26, #28 & #30, compile it, fix any errors, execute it, fix any errors and post the working version here.

    DrawRectange is public, should be declared in a file named DrawRectange.java
    A class declared as public must be in a file with the filename the same as the classname.
    There can not be two public classes defined in the same file.

    Either move the definition of DrawRectangle to a file named: DrawRectange.java
    or remove the public modifier from the class definition.


    This is an interesting comment in the code:
    /*
     *  Stacktrace.in
     *  You have a exception , we have a solution
     */

    There can only be ONE class that is public in a .java file and the classname and filename must match,

    BTW whoever wrote the code does not know how to spell Rectangle.
