Java – store multiple values in the mapping of a single key

I have the following name in C: ght Txt, which contains the following data

Id|ytr|yts
1|W|T
2|W|T
3|W|T

The problem now is that the positions of these columns (ID | YTR | YTS) are not in order, which means that they can also shuffle

Id|ytr|dgfj|fhfjk|fgrt|yts

Or they can be like

Id|wer|ytr|weg|yts

So I did the following and read them in Java, as shown below

String[] headers = firstLine.split("|");
int id,Ix,Ixt,count = 0;

for(String header : headers) {
    if(header.equals("Id")) {
        idIx = count;
    }elseif (header.equals("Ix")) {
        Ixt = count;
    } elseif (header.equals("Ixt")) {
        Ixt = count;
    }
    count++;
}

Now I need to store them in a map to prevent ID. I will get the values of columns YTR and YTS, so there should be a single key in the map, but there may be multiple key values. Please tell me how to store them in the map

Solution

Using map < integer, list < string > > sounds like the first feasible method

Because it sounds like your value is structured, it may be better to create a value class, for example Map < integer, yourvalueclass > where

class YourValueClass
{
    String ix;
    String ixt;

    // constructor,getters and setters
}

Basically, you should consider classes / objects - not in object denial
