Java - Как правильно организовать хранение пары: команда -> строки_результата

Какие getKey? Что за getValue? Кто (включая автора через пару недель) этот бред разберёт?

public class CommandResultPair {
    private String command;
    private List<String> result;
    ...
    // get, set, construct...
}
...
List<CommandResultPair> crps = new ArrayList<>();
while (...) {
    String commnad = ...
    List<String> result = ...
    crps.add(new CommandResultPair(command, result));
}
...
for(CommandResultPair crp : crps) {
    String command = crp.getCommand();
    List<String> result = crp.getResult();
    ...
}

Сделал отдельный класс:

public class CommandResultPair {
private final String  command;
private final ArrayList<String> result;

public CommandResultPair(String command, ArrayList<String> result) {
    this.command = command;
    this.result = result;
}
public String getCommand() { return command; }
public ArrayList<String> getResult() { return result; }
@Override
public int hashCode() { return command.hashCode() ^ result.hashCode(); }
@Override
public boolean equals(Object o) {
     if (!(o instanceof CommandResultPair)) return false;
    CommandResultPair pairo = (CommandResultPair) o;
    return this.command.equals(pairo.getCommand()) &&
            this.result.equals(pairo.getResult());
}}

Так проверяю:

public class ExampleCommanResultPair {
public static void main(String[] args) {

    String str1 = "command1";
    String str2 = "command2";
    ArrayList<String> result1 = new ArrayList<String>();
    result1.add("result1_line1");
    result1.add("result1_line2");
    ArrayList<String> result2 = new ArrayList<String>();
    result2.add("result2_line1");
    result2.add("result2_line2");
    CommandResultPair cmd1 = new CommandResultPair(str1,result1);
    CommandResultPair cmd2 = new CommandResultPair(str2,result2);

    ArrayList <CommandResultPair> commandArray = new ArrayList<>();
    commandArray.add(cmd1);
    commandArray.add(cmd2);
    commandArray.add(new CommandResultPair("command3",result1));
    for (CommandResultPair cmdItr : commandArray){
        System.out.println("Result for command \"" + cmdItr.getCommand() + "\"");
        cmdItr.getResult().forEach((resultItr) -> {System.out.println( resultItr   );}     );

    }
}}

Вывод:

    Result for command "command1"
result1_line1
result1_line2
Result for command "command2"
result2_line1
result2_line2
Result for command "command3"
result1_line1
result1_line2

Вроде бы то, что нужно.
