我在JCREATOR里复制代码了,老是这样的提示
--------------------Configuration: 123 - JDK version 1.6.0_04 <Default> - <Default>--------------------javac: invalid flag: C:\Documents and Settings\Johnny\Desktop\001\123\src\welcome.xml
Usage: javac <options> <source files>
use -help for a list of possible options
Process completed.
我不明白....不是说INVALID FLAG.就是INVALID PATH.
我不明白.....为什么呢??
下面是我复制的代码..
public class Welcome
{
public static void main(String[] args)
{
//System.out.print("维新:http://www.mybole.com.cn\n");
//System.out.println(" Welcome you!");

b=(byte)(b*3);
System.out.println(b);*/

if()
{
}
while(true)
{
}
do
{
}while(true);
for(int i=0;i<10;i++)
{
}
}
} 楼主尝试一下在命令行里面直接用javac编译可不可以。 安全起见，路径中不要有中文或者空白～～ 没有中文.也没有空白啊..
我不会二楼说的...我刚入门
