有人知道jFrame中的jTable是否有显示行限制？我必须在jTable中显示9 500 000行，有人知道这是否可行？
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);
row.add(gabinete.get(i));
row.add(processador.get(j));
row.add(memoria.get(k));
row.add(hd.get(l));
row.add(ssd.get(m));
row.add(gpu.get(n));

row.add(refrigeracao.get(r));
row.add(monitor.get(s));
row.add(headset.get(t));
row.add(motherboard.get(u));
row.add(Double.toString(prob));
model.addRow (row);
cont++;
System.out.println(cont);
row.clear();
}
}
}
}
}
}
}
}
}
}
}
}
}
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new Tela().setVisible(true);
}
});

我认为问题出现在row.clear()中，因为如果删除此代码，则代码可以正常工作，但在表格中显示的值始终相同。
答案 0 :(得分：1)
事实上，我不确定这是否可行。但你可以测试一下。试试这个（尝试自己编写代码）
1-写一个特定的函数，它有一个从零到你感兴趣的大小（比如9500000）的循环。在这个循环中，将类似字符串或迭代次数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）中逐行读取该文件，并将readed作为新行添加到表中。 如果可能，表格将被填充，如果没有，将发生特定的例外。
.......................................... 试试这个
在框架中添加一个完全在列上且没有行的表。
for（int i = 0; i＆lt; 1000000; i ++）
{
//这里向表中添加一个新行
//如果发生错误，请减小循环的大小。
}
