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

Code After Refactoring 1:

Code Before Refactoring 2:

Code After Refactoring 2:

Task

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

Always return a complete and compilable method (Java 17).

Perform intermediate steps internally:

• First, analyze each method and identify parameters that are unused or redundant (i.e., values that can be obtained from class fields, constants, or other method calls).
• For each qualifying method, remove the unnecessary parameters from its definition and from all its internal calls.
• Ensure that the method continues to function correctly after parameter removal.
• Output only the refactored code inside a single java block.
• Do not remove any functionality from the original method.
• Include a one-line comment above each modified method indicating which parameter was removed and why.

Code to be Refactored:

Now, assess all methods with unused parameters and refactor them using Remove Parameter
