I have data stored in database i want to retrieve it and print it by splitting spaces and replace it with comma, and after 6th point i want to go to new line,plus ignoring comma at the last 6th point
the data are like this :

i've tried this, How can i get it in proper way?

Java

int sum=0;
String values = null;
    while (rs.next()) {

      values = rs.getString(1);
      String[] valueTokens = values.split("\\s");
      for(int i=0;i<valueTokens.length;i++){
      System.out.print(valueTokens[i]);
      System.out.print(",");

      if( i % 6 == 0 ) {
         System.out.println();
         sum += i; }
    }
}

Where does this data come from and why are you storing it as strings rather than numbers? You could use the string.format[^] or string.replace[^] method to build your comma separated string for output,

Data come from MySQL database
i stored them in String because i want all points in one record for single Shape, when i need to draw one shape i just retrieve that particular record,especially my shapes are based on cubic curves, which each shape needs 6 points to draw one curve (it should begin with starting point as starting point of the shape)

Hi, what I want to do is to capture live video from a webcam in this java application, but had an error when I run this set of code:

java.io.IOException: Could not connect to capture device
javax.media.NoDataSourceException: Error instantiating class: com.sun.media.protocol.vfw.DataSource : java.io.IOException: Could not connect to capture device

I had already put the jmf.jar into the lib folder.

Java

<pre lang="java">

public class CamRecorder {

CaptureDeviceInfo device = (CaptureDeviceInfo) deviceList.firstElement(); //in this computer the only capture device is in=built webcam stays at 0th position
Format[] formats = device.getFormats(); //get all formats

for (int x = 0; x < formats.length; x++) {
if (formats[x] != null && formats[x] instanceof VideoFormat) {
videoFormat = (VideoFormat) formats[x]; //take the video format
videoDevice = device;
}
/*if (formats[x] != null && formats[x] instanceof AudioFormat) {
audioFormat = (AudioFormat) formats[x]; //take the audio format
//audioDevice = device;
}*/
}
//create data sources

deviceList = CaptureDeviceManager.getDeviceList(new VideoFormat(null)); //get all media devices

My question is should i start a new project then import the file?

Thanks in advance

I have not used IntelliJ, but assuming you are trying to use http://gridworld.javawide.org/index.php/BugRunner[^], then I think you need to start a new project. Give it a try and see what happens.

A five for the effort, but alas still can't import the project. I guess i'll move on to chapter 6 and hope I don't miss much.

Thanks anyway. Thumbs Up | :thumbsup:

Import into what? Have you tried just creating a new project and using copy and paste to add the source code?

The points are stored in MySQL database in data-type of MEDIUM-TEXT, these examples of the points (coordinates)stored in this form(Starting two points are moveTo and each line is a curve)

all the above points have same Object-ID.
So, my question is How can i create GeneralPath objects to draw the shapes, I know there's a method curveTo() used to Add a curved segment, defined by three new points, to the path by drawing a Bézier curve, and How can i use all these points(coordinates) to draw curve on JFrame also i have so many others i need to combine all of them together based on Object-ID's ?
The program is :

Java

import java.sql.*;

public class selectStmt {
	private static final String DB_DRIVER = "com.mysql.jdbc.Driver";
	private static final String DB_CONNECTION = "jdbc:mysql://127.0.0.1:3306/abo";
	private static final String DB_USER = "username";
	private static final String DB_PASSWORD = "pswd";
	
	public selectStmt(){
		try {
			 
			selectRecordsFromTable();
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		}
 
	}
 
	private static void selectRecordsFromTable() throws SQLException {
 
		Connection dbConnection = null;
		PreparedStatement preparedStatement = null;
 
		String selectSQL = "SELECT * FROM abo.pathitems where ObjectID=1";
 
		try {
			dbConnection = getDBConnection();
			preparedStatement = dbConnection.prepareStatement(selectSQL);
			//preparedStatement.setInt(1, 100);
			
			// execute select SQL stetement
			ResultSet rs = preparedStatement.executeQuery();
 
			while (rs.next()) {
                            
				/*  how can i use GeneralPath class here and its functions such as moveTo() and curveTo() to pass all points properly */
			}
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		} finally {
 
			if (preparedStatement != null) {
				preparedStatement.close();
			}
 
			if (dbConnection != null) {
				dbConnection.close();
			}
 
		}
 
	}
 
	private static Connection getDBConnection() {
 
		Connection dbConnection = null;
 
		try {
 
			Class.forName(DB_DRIVER);
 
		} catch (ClassNotFoundException e) {
 
			System.out.println(e.getMessage());
 
		}
 
		try {
 
			dbConnection = DriverManager.getConnection(
                             DB_CONNECTION, DB_USER,DB_PASSWORD);
			return dbConnection;
 
		} catch (SQLException e) {
 
			System.out.println(e.getMessage());
 
		}
 
		return dbConnection;
	}

}
