JOptionPane Multidimensional Array output
Question
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.
For example: userinput[k] next to usernumber[k] then the next row would be userinput[k+1] next to usernumber[k+1]
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]);
}

Build your output into a single String .
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());

使用StringBuilder并将数组的每个元素连接到显示消息中，
