java - 如何让我的程序在 Java 窗口中运行？

Question

我正在学习 Java，并认为尝试和学习的最佳方法是创建一个小型文本冒险，它实际上包含了我实际上正在尝试学习的某些功能。

所以，我一直在通过反复试验慢慢构建我的小游戏，现在我希望在实际窗口中而不是在 IDE 本身中显示它。

这是名为 RoleGame 的类:

package rolegame;

import java.util.*;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class RoleGame extends JFrame{


public static void main(String[] args){
    RoleGame RoleGameObject = new RoleGame();
    RoleGameObject.roleGame();

}



public void roleGame() {
    JPanel roleGame = new JPanel();
    add(roleGame);
    this.setSize(1000, 1000);
    // pack();
    setVisible(true);



    TheFellowship TheFellowshipObject = new TheFellowship();
    TheFellowshipObject.yourParty();
    System.out.println();
    FellowshipInventory FellowshipInventoryObject = new FellowshipInventory();
    FellowshipInventoryObject.inventory();
    FellowshipAttributes FellowshipAttributesObject = new FellowshipAttributes();
    FellowshipAttributesObject.characterAttributes();


    Scanner in = new Scanner(System.in);

    System.out.println();
    System.out.println("You face a horde of terrible orcs...\nWhat are you going to do?\n\nYour options are as follows:\n ");
    System.out.println("Roll a 1 to run...\nRoll a 2 to stand your ground...");
    System.out.println("Roll a 3 to attack...\nRoll a 4 to attack the leader...");
    System.out.println("Roll a 5 to have your whole party attack...\nRoll a 6 to kill them all...");
    System.out.println();
    System.out.print("Press return to roll the dice!!");
    in.nextLine();

    //System.out.println("You rolled a "+ num());
    for(int i = 0; i < 1; i++){
        int num = (int) (Math.random() * 6) + 1;
        System.out.println("You rolled a " + num + "\n");
    if(num == 1){
        System.out.println("You run away to fight another day when the odds are better...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.youRun();
    }
    else if(num == 2)
    {
        System.out.println("You stand your ground before the mighty horde...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.standGround();
    }
    else if(num == 3)
    {
        System.out.println("You run towards your foe screaming at them as you go...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.attack();
    }
    else if(num == 4)
    {
        System.out.println("You seek out the horde leader and make for him with your sword swinging...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.attackLeader();
    }
    else if(num == 5)
    {
        System.out.println("You rally your party by shouting for their assistance to slain the horde...");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.rally();
    }
    else if(num == 6)
    {
        System.out.println("You and your party storm the horde and slain them all and cry    victory...!!");
        TheHorde TheHordeObject = new TheHorde();
        TheHordeObject.killThem();
    }
    Fighting FightingObject = new Fighting();
    FightingObject.fight();

    }

  }

}

首先，请接受我对原始代码的歉意。我相信您会理解我们都是从底层开始的，这对于学习 Java 的人来说是一个很大的学习曲线。

目前我的代码有一些小问题，但我真的很想在自己的窗口中看到它，然后纠正我的其他错误。

非常感谢。

您首先必须构建一个可执行文件 *. jar 文件。执行此操作取决于 IDE，例如在 Eclipse 中:

http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftasks-33.htm

在 Netbeans 中: http://www.wikihow.com/Generate-JAR-File-in-Netbeans

您可以使用以下命令在命令行中运行 jar 文件:

java -jar <your_jar_file>.jar

您还可以从中生成一个 exe 文件，但这本身就是一个主题。
