    [RESOLVED] Code malfunction

    Hello there . I'm still a beginner at java had to write a program to print a hallow rectangle of asterik using for loops with predefined values which means I don't ask user to input anything . This is my code :

    Code:
    public class rectangle { 
    
    public static void rectangle (String  args []) {
    
         for (int i = 0; i < 10 ; i++) {
    
    
               for (int j = 0; j < 4 ; j++) {
    
                   System.out.print("*");
     
               }
      
                 System.out.println("");
    
           }
     
         } 
                  System.out.println("");
     }

    I had an error with main which I didnt know what is it and I don't know if the curly braces is doing an error or something any idea . Thanks for your help

    Code:
                System.out.println("");
    
           }
     
         } 
                  System.out.println("");
     }
    The second .println() is outside the function rectangle. Do you mean

    Code:
                System.out.println("");
    
           }
           System.out.println("");
     
         } 
    }

    By the way, that code prints a solid rectangle. To print a hollow rectangle as required you should first print the top line (all *), then a series of lines consisting of an * at each end and spaces separating them, and finally the bottom line (all * again).

    The first thing you need to do is find out what malfunction code(s) are presently set in the ECM. You can read these malfunction codes in several different ways.
