我正在尝试创建一个HashMap,HashMap所以我将来更容易访问它的元素,如下所示.

问题是它只重复while循环的最后一个元素而不是其余元素.

HashMap<String,String> result = new HashMap<>();
HashMap<Integer, HashMap<String,String>> fr = new HashMap<>();

int i = 0;
try {
    ResultSet rq = qexec.execSelect();
    // ResultSetFormatter.out(System.out, rq, query);

    // get result from SPARQL query
    while (rq.hasNext()) {
        QuerySolution soln = rq.next();
        id = soln.getLiteral("?id").getLexicalForm();
        //...
        result.put("id",id);
        //...
        if (soln.getLiteral("?wateruse") != null) {
            wateruse = soln.getLiteral("?wateruse").getLexicalForm();
            //...
            result.put("wateruse",wateruse);
        } else {
            System.out.println("NO");
        }               

        fr.put(i, result);
        i++;
    }
} finally {
    qexec.close();
}

这是结果应该是这样的:
