What is better: multiple “if” statements or one “if” with multiple conditions?

by

One golden rule I follow is to “Avoid Nesting” as much as I can. But if it is at the cost of making my single if condition too complex, I don’t mind nesting it out.

Besides you’re using the short-circuit && operator. So if the boolean is false, it won’t even try matching!

So,

if (boolean_condition && matcher.find(string)) {
    ...
}

is the way to go!
