How does Java deal with multiple conditions inside a single IF statement

Question

Lets say I have this:

if(bool1 && bool2 && bool3) {
...
}

Now. Is Java smart enough to skip checking bool2 and bool2 if boo

Answer 1

Yes, Java (similar to other mainstream languages) uses lazy evaluation short-circuiting which means it evaluates as little as possible.

This means that the following code is completely safe:

if(p != null && p.getAge() > 10)

Also, a || b never evaluates b if a evaluates to true.
