Question

从以下数组列表中，我需要删除逗号并将每个元素添加到JTable中的单元格。例如，My JTable - 将有12列，第1行应填0 0 0 ....

请求您帮助我从列表中删除逗号并将元素添加到JTable中的单元格。

//代码

ArrayList list = new ArrayList（）;

list.add（＆＃34; 0,0,0,4,2,0,2,0,1,0,0,0和＃34;）;

list.add（＆＃34; 1,0,0,4,2,0,3,0,1,0,0,1和＃34;）;

list.add（＆＃34; 2,0,0,4,1,0,2,0,1,0,0,0和＃34;）;

Answer 1

ArrayList list = new ArrayList();

list.add("0 , 0 , 0 , 4 , 2 , 0 , 2 , 0 , 1 , 0 , 0 , 0");

list.add("1 , 0 , 0 , 4 , 2 , 0 , 3 , 0 , 1 , 0 , 0 , 1");

list.add("2 , 0 , 0 , 4 , 1 , 0 , 2 , 0 , 1 , 0 , 0 , 0");

//now go through the ArrayList and split each entry by ',' and add to a 2D array, JTable

int[][] JTable = new int[list.size()][];
for (int row = 0; row < list.size(); row++) {
    //get an item from the ArrayList
    String rowString = list.get(row);
    //remove all the whitespaces from the string
    rowString = rowString.replaceAll("\\s+","");
    //split the string using "," as a delimiter
    String[] items = rowString.split(",");
    JTable[row] = new int[items.length];
    for (int col = 0; col < items.length; col++) {
        JTable[row][col] = Integer.parseInt(items[col]);
    }
}

Answer 2

以下代码正常运行！发布代码以帮助其他程序员....

//新逻辑 for（int row = 0; row＆lt; recommendedTestSet.size（）; row ++）

    {

        String rowString = recommendedTestSet.get(row);

        rowString = rowString.replaceAll("\\s+","");

        String[] items = rowString.split(",");

        rtsTable.addRow(items);
    }
