Boolean Prefix (ARCH4007)

Key java.naming.boolean-prefix · Severity info · Category naming

Boolean-typed fields and accessors should carry an interrogative prefix (is/has/can/should); otherwise conditionals read poorly.

Incorrect

public class Account {
    private boolean active;
    public boolean active() { return active; }
}

Correct

public class Account {
    private boolean active;
    public boolean isActive() { return active; }
}

Fix

Add an is/has/can/should prefix to boolean members and accessors.
