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));
    }
}

Code After Refactoring 1:

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

Code Before Refactoring 2:

NodeImpl( long id, long firstRel, long firstProp )
{
     this( id, false );
}

Code After Refactoring 2:

NodeImpl( long id)
{
     this( id, false );
}

Task

Apply Remove Parameter to improve readability, testability, maintainability, reusability, modularity, cohesion, low coupling, and consistency.
