Question

我有比较相似度的得分列表，我希望在得到Array之后像这样array[][]制作Array多维，它将是总和列和行。但我不知道要宣布这一点。

这是我的代码：

List<List<Sentence>> collect = Arrays.asList(new File(p).listFiles()).stream()
            .map((x) -> configSentenceByLine(x.getAbsolutePath()))
            .map((x) -> tokenizingWord(x))
            .map((x) -> stemmingWord(x))
            .map((x) -> countWordBased(x))
            .collect(Collectors.toList());

    double sim = 0.0;
    for (int k = 0; k < collect.size(); k++) {
        for (int i = 0; i < collect.get(k).size(); i++) {
            for (int m = k + 1; m < collect.size(); m++) {
                for (int j = 0; j < collect.get(m).size(); j++) {
                    SimilarityMeasure ss = new SimilarityMeasure();
                    sim = ss.getSimilarity(collect.get(k).get(i).getSentence(), collect.get(m).get(j).getSentence());
                }
            }
        }
    }

如果有2个文件我可以申报，我可以得到总和列和行。

在声明2个文件的代码下方。

double[][] simMat = new double[collect.get(0).size()][collect.get(1).size()];        
    for (int k = 0; k < collect.get(0).size(); k++) {
        for (int i = 0; i < collect.get(1).size(); i++) {
            simMat[k][i] = (double) (nc.getSimilarity(collect.get(0).get(k).getSentence(), collect.get(1).get(i).getSentence()));                
        }
    }

但是如果文件有5个或更多，我都不知道要宣布这个。

也许你可以拆分成单独的数组并创建一个数组数组，然后从那里进行操作。下面的例子只是剪切和粘贴并保存为html文件并在浏览器中运行。希望它有所帮助。

<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>

<script>
///// array of arrays /////
///// create array [a] with three elements /////
var a=[1,2,3];

///// create array [b] with three elements /////
var b=[4,5,6];

///// create array c with two elements [array a and array b]     ///// 
var c=[a,b];

///// create variable d /////
var d;

///// put element 0 of array c into variable d /////
///// as element 0 of array c is array a /////
///// array a is passed into variable d a=[1,2,3] ///// 
d=c[0]

///// proof print out 2nd element of variable d /////
///// prints out 2 which is 2nd element of array a /////
///// which was stored as first element of array c ///// 
document.getElementById("demo").innerHTML = d[1];
</script>


</body>
</html>

如何从java中的多个值声明数组？
