    Unhappy How to solve this problem in Programming

    I'm a beginner, please note, I have the following problem and I didn't find a solution on how to solve it, I'm trying to create this, what is the most appropriate way to solve this?

    A bank has a portfolio of thousands of trades and they need to be categorized.
    A trade is a commercial negotiation between a bank and a client.
    Each trade has a value that indicates the transaction amount in dollars and a text indicating if the client´s sector is "Public" or "Private". They implement the following interface:

    interface ITrade
    {
    double Value { get; }
    string ClientSector { get; }
    }

    Currently, there are three categories:
    LOWRISK: Trades with value less than 1,000,000 and client from Public Sector
    MEDIUMRISK: Trades with value greater than 1,000,000 and client from Public Sector
    HIGHRISK: Trades with value greater than 1,000,000 and client from Private Sector

    Imagine you receive a list of trades and you need to return a list of categories as below:
    input: List<ITrade> portfolio
    output: List<string> tradeCategories

    Example:
    Input:
    Trade1 {Value = 2000000; ClientSector = "Private"}
    Trade2 {Value = 400000; ClientSector = "Public"}
    Trade3 {Value = 500000; ClientSector = "Public"}
    Trade4 {Value = 3000000; ClientSector = "Public"}
    portfolio = {Trade1, Trade2, Trade3, Trade4}

    Output:
    tradeCategories = {"HIGHRISK", "LOWRISK", "LOWRISK", "MEDIUMRISK"}

    Keep in mind that category rules may be added/removed/modified in the future and be highly complex.
    Please write your answer in pseudo-code showing clearly what classes, interfaces, methods and design patterns you would create/use to solve this problem. Also, object oriented programming is appreciated.

    What have you tried? Do you have any specific java programming questions about your assignment?

    Be sure to wrap all posted code in code tags.

    the problem:

    Each trade has a value that indicates the transaction amount in dollars and a text indicating if the client´s sector is "Public" or "Private". They implement the following interface:

    interface ITrade
    {
    double Value { get; }
    string ClientSector { get; }
    }

    Currently, there are three categories:
    LOWRISK: Trades with value less than 1,000,000 and client from Public Sector
    MEDIUMRISK: Trades with value greater than 1,000,000 and client from Public Sector
    HIGHRISK: Trades with value greater than 1,000,000 and client from Private Sector

    Imagine you receive a list of trades and you need to return a list of categories as below:
    input: List<ITrade> portfolio
    output: List<string> tradeCategories

    Example:
    Input:
    Trade1 {Value = 2000000; ClientSector = "Private"}
    Trade2 {Value = 400000; ClientSector = "Public"}
    Trade3 {Value = 500000; ClientSector = "Public"}
    Trade4 {Value = 3000000; ClientSector = "Public"}
    portfolio = {Trade1, Trade2, Trade3, Trade4}

    Output:
    tradeCategories = {"HIGHRISK", "LOWRISK", "LOWRISK", "MEDIUMRISK"}

    Keep in mind that category rules may be added/removed/modified in the future and be highly complex.
    Please write your answer in pseudo-code showing clearly what classes, interfaces, methods and design patterns you would create/use to solve this problem. Also, object oriented programming is appreciated.

    what I tried: I read this whole tutorial that explains what pseudo code is and uses java as an example: https://www.geeksforgeeks.org/how-to...a-pseudo-code/, but I don't know how to do it.

    some code: if (Trade.index(I).tradeValue < 1000000 and Trade.index(I).client ==< publicSector) Print (low risk)

    See my last post.

    I don't know how to do it.
    Can you ask your instructor for help with that?
