[Solved] If statements inside else if [closed]

by


It is not only OK; I’d even recommend it, especially if conditionB is relatively expensive to evaluate. For instance, here’s an alternative way:

if(conditionA) {
    //do A stuff
} else if(conditionB && conditionB1) {
    //do B1
} else if(conditionB && conditionB2) {
    //do B2
} else if(conditionB && conditionB3) {
    //do B3
}

Let’s say that conditionB is evaluated by a method (like boolean getConditionB() {...}) and getConditionB() is expensive to execute. The JVM would have to execute your expensive method on every possibility, so your approach is better.
