jtable 允许的最大行数

Question

有人知道jFrame中的jTable是否有显示行数限制？我必须在 jTable 中显示 9 500 000 行，有人知道这是否可能？

我的代码：

private void jButton1MouseClicked(java.awt.event.MouseEvent evt) {

        double prob;
        Vector row = new Vector();
        int cont=0;
        DefaultTableModel model = (DefaultTableModel) jTable1.getModel();
        for (int i = 0; i < 2; i ++) {
            for (int j = 0; j < 4; j++){
                for (int k = 0; k < 4; k++){
                    for (int l = 0; l < 3; l++){
                        for (int m = 0; m < 4; m++){
                            for (int n = 0; n < 4; n++){
                                for (int o = 0; o < 3; o++){
                                    for (int p = 0; p < 4; p++){
                                        for (int q = 0; q < 4; q++) {
                                            for (int r = 0; r < 2; r++){
                                                for (int s = 0; s < 4; s++){
                                                    for (int t = 0; t < 4; t++){
                                                        for (int u = 0; u < 4; u++) {
                                                             prob = ((pesogabinete * retornaSimGabinete(gabinetesel,gabinete.get(i))) + (pesoprocessador *(retornaSimProc(processadorsel,processador.get(j)))) + (pesomemoria * (retornaSimMem(memoriasel,memoria.get(k)))) + (pesohd * (retornaSimHd(hdsel,hd.get(l)))) + (pesossd * (retornaSimSsd(ssdsel,ssd.get(m)))) + (pesogpu * (retornaSimGpu(gpusel,gpu.get(n)))) +  (pesoteclado * (retornaSimTeclado(tecladosel,teclado.get(o)))) + (pesomouse * (retornaSimMouse(mousesel,mouse.get(p)))) + (pesofonte * (retornaSimFonte(fontesel,fonte.get(q)))) + (pesorefrigeracao * (retornaSimRefrigeracao(refrigeracaosel,refrigeracao.get(r)))) + (pesomonitor * (retornaSimMonitor(monitorsel,monitor.get(s)))) + (pesoheadset * (retornaSimHeadset(headsetsel,headset.get(t)))) + (pesomotherboard * (retornaSimMotherboard(motherboardsel,motherboard.get(u))))) / (pesogabinete+pesoprocessador+pesomemoria+pesohd+pesossd+pesomouse+pesoteclado+pesogpu+pesofonte+pesorefrigeracao+pesomonitor+pesoheadset+pesomotherboard);

我相信问题出在row.clear()，因为如果我删除它，代码可以工作，但在表中总是显示相同的值。

Answer 1

事实上，我不确定这是否可能。但是你可以测试一下。试试这个（尝试自己写代码）

1- 编写一个特定的函数，该函数具有从零到您感兴趣的大小（比如 9500000）的循环。在这个循环中，将字符串或迭代次数之类的内容写入预定义的输出文件（逐行）。

2- 然后在另一个函数（比如填充表）中从该文件中逐行读取，并将读取的内容作为新行添加到表中。 如果可能，表格将被填满，如果没有，则会发生特定异常。

.................................................. 试试这个

在您的框架中添加一个完全在列且没有行的表格。

for (int i=0;i

{

//这里向表中添加新行

//如果发生错误，减小循环的大小。

}
