Matching braces always line up vertically in the same column as their construct.
example:

void foo()
{
    while (bar > 0)
    {
        System.out.println();
        bar--;
    }

    if (oatmeal == tasty)
    {
        System.out.println("Oatmeal is good and good for you");
    }
    else if (oatmeal == yak)
    {
        System.out.println("Oatmeal tastes like sawdust");
    }
    else
    {
        System.out.println("tell me pleeze what iz dis 'oatmeal'");
    }

    switch (suckFactor)
    {
        case 1:
            System.out.println("This sucks");
            break;
        case 2:
            System.out.println("This really sucks");
            break;
        case 3:
            System.out.println("This seriously sucks");
            break;
        default:
            System.out.println("whatever");
            break;
    }
}

All if, while and for statements must use braces even if they control just one statement.

Reasoning: Consistency is easier to read. Plus, less editing is involved if lines of code are added or removed.

    if (superHero == theTick) System.out.println("Spoon!");  // NO!

    if (superHero == theTick)
        System.out.println("Spoon!");  // NO!

    if (superHero == theTick) {
        System.out.println("Spoon!");
    }                                            // NO!

    if (superHero == theTick)
    {
        System.out.println("Spoon!");
    }                                            // YES!
