Apex

Jump statements (return, break, continue) and throw expressions move control flow out of the current code block. So any statements that come after a jump are dead code.

Noncompliant Code Example

Integer foo(Integer a) {
    Integer i = 10;
    return i + a; // Noncompliant 
    i++; // dead code
}

Compliant Solution

Integer foo(Integer a) {
    Integer i = 10;
    return i + a; // Noncompliant 
}
