如何在JAVA中用类似C++中的System("...")?

[zhenming_liu]

譬如, System("cls");

等待ING...

有！！！如下：
Runtime rt=Runtime.getRuntime();
Process p=rt.exec("...");

[zhenming_liu]

SORRY呀, 有EXCEPTION, 不太懂:(

java.io.IOException: CreateProcess: cls error=2
at java.lang.Win32Process.create(Native Method)
at java.lang.Win32Process.<init>(Win32Process.java:63)
at java.lang.Runtime.execInternal(Native Method)
at java.lang.Runtime.exec(Runtime.java:566)
at java.lang.Runtime.exec(Runtime.java:428)
at java.lang.Runtime.exec(Runtime.java:364)
at java.lang.Runtime.exec(Runtime.java:326)
at SysCall.main(SysCall.java:10)

[zhenming_liu]

//我的整个程序
public class SysCall
{
public static void main(String[] args)
{
Runtime rt=Runtime.getRuntime();
try
{
Process p=rt.exec("hi");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

还在等~

[yuebenxian]

Runtime类的exec方法.可以.

[zhenming_liu]

but as stated above, cause exception boh...

给你个正确的实例，已调试通过：

import java.io.*;
public class SysCall
{

public static void main(String args[])
{

try{
Runtime.getRuntime().exec("notepad.exe");
}
catch(IOException ex)
{
System.out.println(ex.getMessage());
}


}
}

调用记事本打开D盘的one1.txt文本文件！

import java.io.*;
public class Test3
{
public static void main(String[] args)throws IOException
{
Runtime rt=Runtime.getRuntime();
//rt.exec("notepad.exe"); 只调用记事本程序！
rt.exec("notepad.exe d:/one1.txt");调用记事本打开D盘的one1.txt文本文件！

}
}
