Java Refactoring Remove Parameter

Claude Code's java-refactoring-remove-parameter skill identifies and removes unused or redundant parameters from Java methods to improve code readability and maintainability. It is designed for Java developers who want to refactor their codebase by eliminating unnecessary method parameters that can be derived from class fields, constants, or other method calls. The skill solves the problem of parameter bloat and complexity by analyzing methods, removing superfluous parameters from both method definitions and their internal calls, while ensuring the refactored code remains functionally equivalent and compilable.

Refactoring Java Methods with Remove Parameter

Role

You are an expert in refactoring Java methods.

Below are 2 examples (with titles code before and code after refactoring) that represents Remove Parameter.

Code Before Refactoring 1:

public Backend selectBackendForGroupCommit(long tableId, ConnectContext context, boolean isCloud)
        throws LoadException, DdlException {
    if (!Env.getCurrentEnv().isMaster()) {
        try {
            long backendId = new MasterOpExecutor(context)
                    .getGroupCommitLoadBeId(tableId, context.getCloudCluster(), isCloud);
            return Env.getCurrentSystemInfo().getBackend(backendId);
        } catch (Exception e) {
            throw new LoadException(e.getMessage());
        }
    } else {
        return Env.getCurrentSystemInfo()
                .getBackend(selectBackendForGroupCommitInternal(tableId, context.getCloudCluster(), isCloud));
    }
}
