用java实现在命令方式清屏

java实现清屏功能

1. 编写一个类ClearScreen.java

public class ClearScreen{

Static

{

loadLibrary("Clear");

}

public native static void clearScreen();

public static void main(String[] args){

clearScreen();

}

}

2. javac ClearScreen.java -> ClearScreen.class

3. javah ClearScreen -> ClearScreen.h

4. 编写ClearScreen.cpp实现native方法clearScreen();

#include <<FONT
face=Arial>jawt_md.h >

#include "ClearScreen.h"

#include

JNIEXPORT VOID JNICALL Java_ClearScreen_clearScreen(JNIEnv *,
jclass)

{

system("cls");

}

5.安装一个microsoft compiler
编译ClearScreen.cpp，得到Clear.dll

注意：将Jdk安装环境include目录下的jawt_md.h   
jni_md.h
jni.h  jawt.h  
4 个头文件copy到 Microsoft Visual Studio的include目录下

cl -LD ClearScreen.cpp -FeClear.dll

其中 -LD create .dll -Fe name executable file
