Here we will be adding examples of good code, if you want to add somethings, please talk with the integrators first.

• Example for good equals method.
  • You can use the mouse-right-button menu in the source code area of eclipse -> Source -> "Generate hashCode() and equals()..." for template, but refactor it to look like the example bellow:

            @Override
    	public boolean equals(Object object) {
    		
    		if (object == null) {
    			return false;
    		}
    		
    		if (object == this) {
    			return true;
    		}
    		
    		if (object.getClass() != this.getClass()) {
    			return false;
    		}
    		
    		// Custom code here...
    	}
    

• Writing if, else, else if, for, while, do while, try, catch, finally statements, blocks.
  • First of all always put curly brackets after the special word that opens the statement, even if the statement contains one row.

    		if (some_condition) {
    			System.out.println("pass");
    		}
    

  • Insert spaces between the brackets and the words. The opening bracket of a statement is on the row where the statement is!

    		while (some_condition) {
                            // something...
    		}
    

  • When writing conditions put spaces between the operands and the operators!

    		if (a != b) {
    			System.out.println("a is not the same as b");
    		}
    

  • if-else if- else example:

    		if (a != b) {
    			// something...
    		} else if (c != d) {
    			// other thing...			
    		} else if ((b == c) && (a == d)) {
    			// third thing, I put the brackets for easier reading, they are not mandatory.
    		} else {
    			// four...
    		}
    

  • for examples

                    for (i = 0; i < n; i++) {
    			// do something...
    		}
    

                    for (Some_iterable_type some_var : some_iterable) {
    			// do something...
    		}
    

  • try-catch-finally... The same as the above as spacing and etc...

                    try {
    			// some code
    		} catch (Exception e) {
    			// handle exception
    		} finally {
    			// some stuff
    		}
    

• Don't use @SuppressWarnings("all") and @SuppressWarnings("synthetic-access") at all, other like @SuppressWarnings("synthetic-access"), @SuppressWarnings("unchecked"), etc.. you can use, but rarely only when needed!
• We don't have special conventions for naming but don't use long name or stupid ones like "stuff".
• Don't leave commented code where you tried something to be reviewed, we will be not very happy.
• Avoid writing expressions on several lines, instead use variables... but if it's needed for example in statements here are some examples :

Write &&,

to be first on the new line.

		                a == b
				&& c == d
				|| b != g
				&& !flag

• If you Ctrl+Shift+F, please refactor your code not to have something like:

  				res
  						.setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);
  

  to something like

                                  res.setDefaultCloseOperation(
  						WindowConstants.DO_NOTHING_ON_CLOSE);
  

  but again it is advisable to use variables, something like:

                                  int closeOperation = WindowConstants.DO_NOTHING_ON_CLOSE;
                                  res.setDefaultCloseOperation(closeOperation);
