我真的很沮丧.我在任何地方都找不到如何在JOptionPane中将该表打印为窗口(如ShowMessageDialog)的方法,就像在控制台the desired output中打印一样
这是我的代码：
import javax.swing.JOptionPane;
import java.util.*;
public class StarWars {
public static void main(String[] args) {
String [][] gridPlayer = new String [6][6];
Scanner kb = new Scanner (System.in);
String [] rows = {"A", "B", "C", "D", "E", "F", "G", "H"};
for (int i = 0; i < 6; i++){
for (int j = 0; j < 6; j++){
gridPlayer[i][j] = " ~ ";
}
}
System.out.print(" ");
for (int i = 0; i < 6; i++){
System.out.print(" " + rows[i] + " ");
}
System.out.println();
for (int i = 0; i < 6; i++){
System.out.print(" " + i);
for (int j = 0; j < 6; j++){
System.out.print(gridPlayer[i][j]);
}
System.out.println();
}
JOptionPane.showMessageDialog(null, for (int i));
}
}
如果有人知道如何做,将非常感谢您的帮助.
附言存在StarWars类,因为它是一项家庭作业；)
解决方法:
有很多可能的方法,这是一种：您可以使用StringBuilder尝试此方法,然后使用html标签将所有内容放入JLabel中：
StringBuilder sb = new StringBuilder();
sb.append("<html>");
String [][] gridPlayer = new String [6][6];
Scanner kb = new Scanner (System.in);
String [] rows = {"A", "B", "C", "D", "E", "F", "G", "H"};
for (int i = 0; i < 6; i++){
for (int j = 0; j < 6; j++){
gridPlayer[i][j] = " ~ ";
}
}
sb.append("  ");
for (int i = 0; i < 6; i++){
sb.append(" " + rows[i] + " ");
}
sb.append("<br>");
for (int i = 0; i < 6; i++){
sb.append(" " + i);
for (int j = 0; j < 6; j++){
sb.append(gridPlayer[i][j]);
}
sb.append("<br>");
}
sb.append("</html>");
JOptionPane.showMessageDialog(null, new JLabel(sb.toString()));
