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...
		}
}}}
