JAVA如何在控制台清屏!!
谢谢!!

Answer 1

以下的代码可以执行dos命令：   
    
  import   java.util.*;   
  import   java.io.*;   
    
  class   StreamGobbler   extends   Thread   
  {   
          InputStream   is;   
          String   type;   
            
          StreamGobbler(InputStream   is,   String   type)   
          {   
                  this.is   =   is;   
                  this.type   =   type;   
          }   
            
          public   void   run()   
          {   
                  try   
                  {   
                          InputStreamReader   isr   =   new   InputStreamReader(is);   
                          BufferedReader   br   =   new   BufferedReader(isr);   
                          String   line=null;   
                          while   (   (line   =   br.readLine())   !=   null)   
                                  System.out.println(type   +   ">"   +   line);           
                          }   catch   (IOException   ioe)   
                              {   
                                  ioe.printStackTrace();       
                              }   
          }   
  }   
    
  public   class   GoodWindowsExec   
  {   
          public   static   void   main(String   args[])   
          {   
                  if   (args.length   <   1)   
                  {   
                          System.out.println("USAGE:   java   GoodWindowsExec   <cmd>");   
                          System.exit(1);   
                  }   
                    
                  try   
                  {                           
                          String   osName   =   System.getProperty("os.name"   );   
                          String[]   cmd   =   new   String[3];   
  System.out.println(   osName);   
                          if(   osName.equals(   "Windows   2000"   )   )   
                          {   
                                  cmd[0]   =   "cmd.exe"   ;   
                                  cmd[1]   =   "/C"   ;   
                                  cmd[2]   =   args[0];   
                                    
                          }   
                          else   if(   osName.equals(   "Windows   95"   )   )   
                          {   
                                  cmd[0]   =   "command.com"   ;   
                                  cmd[1]   =   "/C"   ;   
                                  cmd[2]   =   args[0];   
                          }   
                            
                          Runtime   rt   =   Runtime.getRuntime();   
                          System.out.println("Execing   "   +   cmd[0]   +   "   "   +   cmd[1]     
                                                                +   "   "   +   cmd[2]);   
                          Process   proc   =   rt.exec(cmd);   
                          //   any   error   message?   
                          StreamGobbler   errorGobbler   =   new     
                                  StreamGobbler(proc.getErrorStream(),   "ERROR");                           
                            
                          //   any   output?   
                          StreamGobbler   outputGobbler   =   new     
                                  StreamGobbler(proc.getInputStream(),   "OUTPUT");   
                                    
                          //   kick   them   off   
                          errorGobbler.start();   
                          outputGobbler.start();   
                                                                            
                          //   any   error???   
                          int   exitVal   =   proc.waitFor();   
                          System.out.println("ExitValue:   "   +   exitVal);                   
                  }   catch   (Throwable   t)   
                      {   
                          t.printStackTrace();   
                      }   
          }   
  }   

Answer 2

然后用以下语句执行即可：   
    
  javac     GoodWindowsExec.java   
  java   GoodWindowsExec   dir   
  pause   
    
  如果楼主不想在运行时才指定要运行的dos命令，可以在上面的文件中指定cmd[2]变量即可

Answer 3

网上很多关于这个问题的讨论，java 无法执行 cls 命令。
楼上的好像是重新打开一个命令窗口。

Answer 4

不知道这个管不管用：
System.out.print("\b\b\b\b\b\b\b\b\b\b\b\b\b\b\b");

Answer 5

摁错了，应该是
System.out.print("\n\n\n\n\n\n\n\n\n\n\n\n\n");
骗人用的。。嘎嘎

Answer 6

我操,你们会不会,不会别在这里瞎JB说.
LZ,你先用C写一个函数,随便叫什么,就是调用了cls()就好,然后把它编译成dll文件,然后写一个头文件
然后在Java中使用JNI载入这个头文件 也就是所谓的native方法你加我qq吧,我给你写了个例子155225572

Answer 7

cls命令也可以阿
手动操作控制台的按钮也可以
