I want to clear my output screen in Java using NetBeans IDE 6.9.1
提问by Brandon Durst
My entire code can be found at the link below, I'm linking it for the sake of a shorter post
我的整个代码可以在下面的链接中找到，我链接它是为了更短的帖子
I want to clear the Output screen, I'm to make the program simulate a user pressing ctrl+L, which in NetBeans IDE 6.9.1 (which I'm using) clears my output window. However, I'm getting errors with my code.
我想清除输出屏幕，我要让程序模拟用户按下 ctrl+L，这在 NetBeans IDE 6.9.1（我正在使用）中清除我的输出窗口。但是，我的代码出现错误。
public static void clearme()
{
try
{
botthing pressbot = new botthing();
pressbot.keyPress(17); // Holds CTRL key.
pressbot.keyPress(76); // Holds L key.
pressbot.keyRelease(17); // Releases CTRL key.
pressbot.keyRelease(76); // Releases L key.
}
catch (AWTException ex)
{
Logger.getLogger(LoginPage.class.getName()).log(Level.SEVERE, null, ex);
}
}
My errors were...
我的错误是...
Cannot find symbol symbol: class botthing
找不到符号符号：类botthing
cannot find symbol symbol: class AWTException
找不到符号符号：类 AWTException
cannot find symbol symbol: variable Logger
找不到符号符号：变量记录器
cannot find symbol symbol: class LoginPage
找不到符号符号：类 LoginPage
cannot find symbol symbol: variable Level
找不到符号符号：变量级别
HOWEVER!After adding these import statements
然而！添加这些导入语句后
import java.awt.AWTException;
import java.util.*;
import java.io.*;
import java.util.logging.Level;
import java.util.logging.Logger;
my errors are...
我的错误是...
cannot find symbol symbol: class botthing location: class program2
找不到符号符号：类botthing位置：类program2
exception java.awt.AWTException is never thrown in body of corresponding try statement
异常 java.awt.AWTException 永远不会在相应的 try 语句的主体中抛出
cannot find symbol symbol: class LoginPage location: class program2
找不到符号符号：类 LoginPage 位置：类 program2
I'm not sure what those mean, but I think the java.awt error could be related to my main(), which is public static void main(String[] args) throws IOException
我不确定这些是什么意思，但我认为 java.awt 错误可能与我的 main() 有关，它是 public static void main(String[] args) throws IOException
All I want to do is clear my output screen. I've also tried
我想要做的就是清除我的输出屏幕。我也试过
for(int x=0;x<999;x++)
{
System.out.print("\b\b\b\b\b");
}
and
和
Runtime.getRuntime().exec("cls");
but both to no avail.
但两者都无济于事。
If the code I've been trying can't be easily fixed, or if someone knows an easier way, I'd love to know. To clarify, all I want to do is clear my Output window after multiple System.out.println's and such.
如果我一直在尝试的代码无法轻松修复，或者有人知道更简单的方法，我很想知道。澄清一下，我想要做的就是在多个 System.out.println 等之后清除我的输出窗口。

botthing is not something defined in the JDK, and if it is a class that you defined, your compiler is not finding it.
botthing 不是 JDK 中定义的东西，如果它是您定义的类，则您的编译器找不到它。
Try using:
尝试使用：
try {
Robot pressbot = new Robot();
pressbot.keyPress(17); // Holds CTRL key.
pressbot.keyPress(76); // Holds L key.
pressbot.keyRelease(17); // Releases CTRL key.
pressbot.keyRelease(76); // Releases L key.
} catch (AWTException ex) {
Logger.getLogger(LoginPage.class.getName()).log(Level.SEVERE, null, ex);
}
