// 這里是代碼？我可以更改什么以僅在一個對話框中顯示輸出？抱歉，我剛開始學習 Java，
uj5u.com熱心網友回復：
您應該首先在 DialogBox 中收集要列印的資料。然后您可以使用 DialogBox 列印資料（不在 for 回圈中）。
看看下面的代碼。
import javax.swing.*;
public class main {
public static long fibonacci(int n){
long a = 0, b = 1;
for (int i = 0; i < n; i ) {
b = a (a = b);
}
return a;
}
public static void main(String... args){
int input = Integer.parseInt(JOptionPane.showInputDialog("Number of print elements"));
String fib = "";
for (int i = 0; i <= input; i ) {
fib = fib fibonacci(i) "\n";
}
JOptionPane.showMessageDialog(null, fib);
}
}
