如何使用Java GUI中执行的循环内部按钮

我用Netbeans编写了一个简单的程序，效果很好。然而，我正在尝试制作一个可执行的jar文件，它将在没有IDE的情况下工作，因此我需要制作一个GUI。我的程序从我这里获取一个输入问题（字符串），并显示一个输出（另一个字符串）。问题和输入存储在两个单独的字符串数组中

这是我的代码，因为在普通java中，循环在主方法中运行良好，但在GUI中，显示了许多错误

这是通用的java代码

package gadhagasker;

import java.util.*;

public class Gadhagasker {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here
    Scanner tc = new Scanner(System.in);
    String[] Answer = {"My name is Gadhagasker.", "I am fine"};
    String[] Question = {"what is your name?", "how are you?"};
    String give = tc.nextLine();
    int a = 0;
    String question = give.toLowerCase();
    for (int i = 0; i < Question.length; i++) {
        if (question.equals(Question[i])) {
            System.out.println("Gadhagasker: " + Answer[i]);
            a = 1;
            break;
        }

    }
    if (a == 0) {
        System.out.println("Gadhagasker: " + "Sorry, I cannot answer that, I am still learning.");
    }
}

}

package-gadhagasker；
导入java.util.*；
