The following code compiles:

Object o=Math.random()<0.5 ? null : new Object();
System.out.println(""+o);

The following code doesn't:

Object o=Math.random()<0.5 ? null : new Object();

if (o==null)
{
}

System.out.println(""+o);

The null check complains that o might be null at the last line, which is just as possible as it was without the if statement.

Even so, it doesn't even matter that o might be null there, as String concatenation works happily with null values.
