About Feature flags for java made easy. Enable. and disable features at runtime - no deployment. Implement multiple paths in your code with predicates evaluated dynamically (if/then/else). Enable features not only with flag values but also drive access with roles and groups (Canary Release). Different frameworks supported starting by Spring Security. Implement custom predicates (Strategy Pattern) to evaluate if a feature is enabled. Some are provided out of the box: White/Black lists ,Time based, Expression based. Connect external source like a Drools rule engine. Keep your code clean and readable: Avoid nested if statements but use annotations. Thanks to Spring AOP target implementation is pick at runtime, and thus driven by feature statuses. For each features execution, ff4j evaluates the predicate therefore it's possible to collect and record events, metrics to compute nice dashboards or draw curves for features usage over time.	About More than a Spring Calculator. ODOP:Spring is a spring design application of the problem-independent Open Design Optimization Platform (ODOP) software. It finds solutions for demanding spring application requirements in mechanical engineering and machine design. Most coil spring calculators require users to manually input values – such as wire diameter, coil diameter, free length and number of coils – and then repeatedly re-analyze until an acceptable solution is reached. ODOP’s ability to invert formula relationships removes that guesswork. Spring design equations are backsolved to meet constraints placed on the problem variables. Need to identify the lightest-possible material weight? Ensure a long spring life and low risk of failure? Our helical coil spring design software can find the constrained extreme of any variable, whether independent or dependent.
