Java 如何将ArrayList添加到表中？

从下面的数组列表中，我需要删除逗号并将每个元素添加到JTable中的一个单元格中。例如，我的JTable-将有12列，第1行应填充为0

请您帮助我从列表中删除逗号，并在JTable中的单元格中添加元素

//代码

ArrayList=新的ArrayList

list.add0,0,0,4,2,0,2,0,1,0,0,0

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]);
    }
}

list.add1,0,0,4,2,0,3,0,1,0,0,1

list.add2,0,0,4,1,0,2,0,1,0,0,0

以下代码工作正常！发布代码以帮助其他程序员

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]);
    }
}

//新逻辑 对于int行=0；行<建议的测试集大小；行++

    {

        String rowString = recommendedTestSet.get(row);

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

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

        rtsTable.addRow(items);
    }

谢谢你，大卫！我正在使用默认表模型将行添加到JTable。。。。所以，让我试试！rowString=rowString.replaceAll\\s+，我可以分隔逗号并显示信息！谢谢你的帮助！永远不要使用默认的表模型。创建您自己的从AbstractTableModel派生的
