Dead Code (ARCH4188)

Key java.quality.dead-code · Severity info · Category quality

Statements after return, throw, break, or continue never execute and mislead the reader. Remove unreachable code.

Incorrect

int compute(int x) {
    if (x > 0) {
        return x * 2;
        log.info("computed");  // unreachable
    }
    return 0;
}

Correct

int compute(int x) {
    if (x > 0) {
        log.info("computed");
        return x * 2;
    }
    return 0;
}

Fix

Delete unreachable statements, or reorder the control flow if the code is actually needed.
