Java中怎么实现带GUI界面的猜数字游戏
作者
这篇文章主要介绍Java中怎么实现带GUI界面的猜数字游戏,文中介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们一定要看完!
先导包
importjava.util.*; importjavax.swing.*;
再写主方法
publicstaticvoidmain(String[]args){ }
新声明一个Scanner和随机数
publicstaticvoidmain(String[]args){ Scannerin=newScanner(System.in); Randomr=newRandom(); }
让UIManager爬取系统窗口样式
try{ UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); }catch(Exceptione){ e.printStackTrace(); }
新建一个int类型的变量存储随机数
intsecret=r.nextInt(32)+1;
写入主程序
JOptionPane.showMessageDialog(null,"电脑随机生成了一个1~32之间的数,请猜出这个数","猜数字游戏",JOptionPane.PLAIN_MESSAGE); Stringnumber2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); intnumber=Integer.parseInt(number2); while(number!=secret){ if(number>secret){ JOptionPane.showMessageDialog(null,"你猜的数大了,请继续猜","猜数字游戏",JOptionPane.PLAIN_MESSAGE); number2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); number=Integer.parseInt(number2); }else{ JOptionPane.showMessageDialog(null,"你猜的数小了,请继续猜","猜数字游戏",JOptionPane.PLAIN_MESSAGE); number2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); number=Integer.parseInt(number2); } } JOptionPane.showMessageDialog(null,"恭喜你,你猜对了,电脑生成的随机数是"+secret,"猜数字游戏",JOptionPane.PLAIN_MESSAGE);
全部代码
packagecom.demo05; importjava.util.*; importjavax.swing.*; publicclassMathDemo03{ publicstaticvoidmain(String[]args){ Scannerin=newScanner(System.in); Randomr=newRandom(); intsecret=r.nextInt(32)+1; try{ UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); }catch(Exceptione){ e.printStackTrace(); } JOptionPane.showMessageDialog(null,"电脑随机生成了一个1~32之间的数,请猜出这个数","猜数字游戏",JOptionPane.PLAIN_MESSAGE); Stringnumber2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); intnumber=Integer.parseInt(number2); while(number!=secret){ if(number>secret){ JOptionPane.showMessageDialog(null,"你猜的数大了,请继续猜","猜数字游戏",JOptionPane.PLAIN_MESSAGE); number2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); number=Integer.parseInt(number2); }else{ JOptionPane.showMessageDialog(null,"你猜的数小了,请继续猜","猜数字游戏",JOptionPane.PLAIN_MESSAGE); number2=(String)JOptionPane.showInputDialog(null,"请输入想猜的数:","猜数字游戏",JOptionPane.PLAIN_MESSAGE,null,null,""); number=Integer.parseInt(number2); } } JOptionPane.showMessageDialog(null,"恭喜你,你猜对了,电脑生成的随机数是"+secret,"猜数字游戏",JOptionPane.PLAIN_MESSAGE); } }
