if ( fiber >= 4 || foam >= 3 )
  System.out.println("House passes the code requirements!" );
else
  System.out.println("House fails." );

Difference between AND and OR

Here is what would happen if a house had 6 inches of fiberglass batting and 0 inches of plastic foam:

fiber >= 4 || foam >= 3
---------    ---------
  true          false
   ---------------
        true

One true is enough.

AND is different from OR. Both of them combine Boolean values ( true/false values ) into one Boolean value. But each does it in a different way:

• All the values AND combines must be true to get a true.
• At least one of the values OR combines must be true to get a true.
