Q2: 怎样运行java小游戏，我只有源代码可是不知道怎么运行
分情况看:
(1)如果你没用非官方集成的开发环境的话,首先在你电脑上装个JDK,然后设置下电脑环境变量,里面有PATH和CLASSPATH这两个参数,具体怎么设置呢?就是把安装目录的地址拷贝到里面就好了,略有不同这两个参数的设置.安装完成后,把源代码文件的目录记下,源代码拷贝到记事本上,把后缀名改成".java";打开CMD窗口,先执行"javac 文件名.java"命令,在目录下会生成一个".class"的文件,那是编译生成的文件,如果顺利通过编译,说明源代码没错误,OK,你再执行"java 文件名.class"就执行程序了.
(2)如果你用的是Eclipse或者Jbuilder这类的集成开发环境的话,那太简单了,导入源代码的文件,点工具栏上的快捷图标,是个平放着的三角形,就可以执行了
总之,你只要把JDK装上,调试成功了,剩余的就小意思,如果实在搞不定,把你代码发过来,我给你生成".jar"文件好了,就像".exe"的可执行文件.呵呵,说了这么多,自己要多摸索下啊,我是学java的,欢迎交流,希望你能顺利解决,编程要自己多摸索
Q3: 求一个简单java程序代码，谢谢

if (i == 1) {
for (int z = 0; z 4; z++) {
System.out.print(" " + star);
}
System.out.println();
}
if (i == 2) {
System.out.print(" ");
for (int x = 0; x 3; x++) {
System.out.print(" " + star);
}
System.out.println();
}
if (i == 3) {
for (int y = 0; y 2; y++) {
System.out.print(" " + star + " ");
}
}
}
}
}
是好使的 但是我没找到画五角星有什么规律（五角星好象不是正规图形吧？）如果还有什么要求的话 补充问题(如果是用*填充所有的东西 不包括 “ ”的话 我可以重新再给你写一个)
