# Java: 'if' Statement - Indentation

## Indent to make programs readable

There are several meathods to make programs readable. How can you easily make the reader see which statements are inside the true part and false part of an `if` statement.

The best way to show this is to indent the statements that are inside. To do this you move the statements to the right by a few spaces. People commonly use two, three, or four spaces. Choose one number (eg, I use 2 or 3), and use it for all programs.

Java doesn't care about your indentation -- it is for humans (including yourself!).

## Example 1 - No indentation - BAD BAD BAD

Here is the `paintComponent()` method from a previous page without indentation. This is small, so it's easy to see which statements are in the true and false parts. If the `if` statement is much larger, it will be unreadable without indentation.

       public void paintComponent(Graphics g) {
       super.paintComponent(g);
       if (marks < 50)
       g.setColor(Color.red);
       else
       g.setColor(Color.black);
       g.drawString("Score = " + marks, 10, 50);
       }

## Example 2 - No indentation and no line breaks

Even a very short method is almost unreadable when you take out the line breaks and spaces. Here is the same method:
`public void paintComponent(Graphics g) {super.paintComponent(g);if (marks<50) g.setColor(Color.red);else g.setColor(Color.black);g.drawString("Score = " + marks,10,50);}`
