eclipse中的代码简写

sysout就可以打出system.out.println();
在Eclipse中的快捷键中把习惯性使用的Alt+/进行代码自动补齐的快捷键改为了ctrl+空格，大家知道这是切换中英文输入法的键，所以需要更改这个快捷键，方法如下：
1.选择eclipse菜单栏中的Window-》preferences；
2.选择General-》keys;
3.在右侧中间的窗体中点击word completion后再点击remove binding,在下方的binding中随便（例如"Alt+."）输入一个快捷键；
4.然后选择Content Assist点击Remove binding，在binding中输入Alt+/；
5.点击Ok就可以了。

如何用eclipse运行一段源代码

把代码复制到eclipse的文件下，在代码区右键，run运行。
不会的话就看下视频就可以运行的了。

运行一个代码所需要的软件

具体需要看是什么类型的代码语言，大部分需要下载
代码分好多种类的
python、Java、等那些需要代码
那种HTML类型的代码不需要下载，记事本写好该文件名后缀就能用浏览器运行

求一份爱心形状特征提取C++opencv的代码

整个项目的结构图：
编写DetectFaceDemo.java,代码如下：
view
plaincopyprint?
package com.njupt.zhb.test;
import org.opencv.core.Core;
import org.opencv.core.Mat;
import org.opencv.core.MatOfRect;
import org.opencv.core.Point;
import org.opencv.core.Rect;
import org.opencv.core.Scalar;
import org.opencv.highgui.Highgui;
import org.opencv.objdetect.CascadeClassifier;
//
// Detects faces in an image, draws boxes around them, and writes the results
// to "faceDetection.png".
//
public class DetectFaceDemo {
public void run() {
System.out.println("\nRunning DetectFaceDemo");
System.out.println(getClass().getResource("lbpcascade_frontalface.xml").getPath());
// Create a face detector from the cascade file in the resources
// directory.
//CascadeClassifier faceDetector = new CascadeClassifier(getClass().getResource("lbpcascade_frontalface.xml").getPath());
//Mat image = Highgui.imread(getClass().getResource("lena.png").getPath());
//注意：源程序的路径会多打印一个‘/’，因此总是出现如下错误
/*
* Detected 0 faces Writing faceDetection.png libpng warning: Image
* width is zero in IHDR libpng warning: Image height is zero in IHDR
* libpng error: Invalid IHDR data
*/
//因此，我们将第一个字符去掉
String xmlfilePath=getClass().getResource("lbpcascade_frontalface.xml").getPath().substring(1);
CascadeClassifier faceDetector = new CascadeClassifier(xmlfilePath);
Mat image = Highgui.imread(getClass().getResource("we.jpg").getPath().substring(1));
// Detect faces in the image.
// MatOfRect is a special container class for Rect.
MatOfRect faceDetections = new MatOfRect();
faceDetector.detectMultiScale(image, faceDetections);
System.out.println(String.format("Detected %s faces", faceDetections.toArray().length));
// Draw a bounding box around each face.
for (Rect rect : faceDetections.toArray()) {
Core.rectangle(image, new Point(rect.x, rect.y), new Point(rect.x + rect.width, rect.y + rect.height), new Scalar(0, 255, 0));
}
// Save the visualized detection.
String filename = "faceDetection.png";
System.out.println(String.format("Writing %s", filename));
Highgui.imwrite(filename, image);
}
}
package com.njupt.zhb.test;

}
// Save the visualized detection.
String filename = "faceDetection.png";
System.out.println(String.format("Writing %s", filename));
Highgui.imwrite(filename, image);
}
}
3.编写测试类：
view
plaincopyprint?
package com.njupt.zhb.test;
public class TestMain {
public static void main(String args) {
System.out.println("Hello, OpenCV");
// Load the native library.
System.loadLibrary("opencv_java246");
new DetectFaceDemo().run();
}
}
//运行结果:
//Hello, OpenCV
//
//Running DetectFaceDemo
///E:/eclipse_Jee/workspace/JavaOpenCV246/bin/com/njupt/zhb/test/lbpcascade_frontalface.xml
//Detected 8 faces
//Writing faceDetection.png
package com.njupt.zhb.test;
public class TestMain {
public static void main(String args) {
System.out.println("Hello, OpenCV");
// Load the native library.
System.loadLibrary("opencv_java246");
new DetectFaceDemo().run();
}
}
//运行结果:
//Hello, OpenCV
//
//Running DetectFaceDemo
///E:/eclipse_Jee/workspace/JavaOpenCV246/bin/com/njupt/zhb/test/lbpcascade_frontalface.xml
//Detected 8 faces
//Writing faceDetection.png

eclipse不是免费吗，为什么我下载要付费呢

eclipse是完全免费的开发工具，源代码开发基于java的可扩展开发平台，最初有IBM公司开发运营，2001年11月开源，像这种功能强大而且开源的工具，一般在下载的时候都会设置一个donate选项，意思是捐赠，估计是你错把donate认成付费了。

下载eclipse的步骤很简单：

1. 你可以百度搜索eclipse，点击进入官网

2. 点击进去之后选择download packages，如果是java开发，一般选择第二个，根据自己系统来选择是哪个版本

3. 点击之后进入下载界面，直接点击download

4. 之后会弹出类似的界面，点击下载就可以了，如果想捐赠，可以选择下面的donate，如果不捐赠的话，就不用管，直接点击弹出来的下载框下载就行
