JOptionPane多维数组输出 [英] JOptionPane Multidimensional Array output
问题描述
好吧，我有要在JOptionPane.showMessageDialog中显示的多维数组.我知道使用System.out.println时会使用for循环.但是，数组大小由用户输入确定，因此我必须使用增量器.
Ok say I have Multidimensional array that I want to display in JOptionPane.showMessageDialog. I know that when using System.out.println, you use a for loop. However the array size is determined by the user input, therefore I have to use a incrementor.
例如:usernumber[k]旁边的userinput[k]，那么下一行将是usernumber[k+1]旁边的userinput[k+1]
For example: userinput[k] next to usernumber[k] then the next row would be userinput[k+1] next to usernumber[k+1]
我遇到的麻烦是，通过使用循环，它每次都在单独的窗口中一次设置一个，而不是在一个窗口中的一个表中一起设置.
The trouble I am having is that by using my loop, it does each set one at a time in separate windows and not all together in a table in one window.
for (int k = 0; k < userinput.length; k++){
JOptionPane.showMessageDialog(null, userinput[k]);
}
for (int k = 0; k < 2; k++){
JOptionPane.showMessageDialog(null, usernumber[k]);
}
推荐答案
将输出构建为单个String.
您可以使用html标签提供其他格式
You can use html tags to provide additional formatting
StringBuilder sb = new StringBuilder(64);
sb.append("<html><table>");
for (int ui = 0; ui = < userinput.length; ui++) {
sb.append("<tr><td>");
sb.append(userinput[ui]);
sb.append("</td>");
for (int k = 0; k < 2; k++){
sb.append("<td>");
sb.append(usernumber[k]);
sb.append("</td>");
}
sb.append("</tr>");
}
sb.append("</table></html>");
JOptionPane.showMessageDialog(null, sb.toString());
