jtable上允許的最大數量行

Question

有人知道jFrame中的jTable是否具有行顯示限制？我必須在jTable中顯示9 500 000行，有人知道這是否可能？

我的代碼：顯示

我相信這個問題是在row.clear()因爲如果我刪除此代碼的作品，但總是在表中顯示相同的值。

Answer 1

事實上，我不確定這是否可行。但是你可以測試它。試試這個（嘗試自己編寫代碼）

1-編寫一個特定的函數，它具有從零到您感興趣的大小（比如9500000）的循環。在此循環中，將字符串或迭代次數寫入預定義的輸出文件（逐行）。然後在另一個函數中（比如填充表）從該文件中逐行讀取，並添加作爲一個新行到表中。 如果可能的話，表格將被填充，否則會發生特定的異常。

.......................................... 試試這個吧

添加到您的框架一個正好在列和沒有行的表。

對（INT I = 0;我< 1000000;我++）

{

//這裏添加一個新行表

//如果發生錯誤，減小尺寸的循環。

}
