[java] Java - Opposite of .contains (does not contain)

I have an if statement:

if (inventory.contains("bread"))

But now I want to check

• if inventory contains "bread"
• but does not contain "water".

How can I do this?

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}
