 Plotting Math Function in JAVA (cos, sin, log, sqrt)

In this tutorial we are going to code a java program that visualize the behavior of mathematical functions (cos, sin, log, sqrt).

Source Code

Steps 

Create a Data Base and name it ‘plot’ then create table ‘chart’ -> rows (Xi,sqrt,exp,cos,sin,ln). don’t forget to add JAR file “JDBC” in Libraries to connect !

then create a class and name it ConnectDB and Copy / Past the code bellow !


Note : Download com.mysql.jdbc_5.1.5.jar 

Link : http://www.java2s.com/Code/Jar/c/Downloadcommysqljdbc515jar.htm


class ConnectDB.java

package hairechetp;

import java.sql.Connection;
import java.sql.DriverManager;
import javax.swing.JOptionPane;

public class ConnectDB {

        Connection conn = null;
    public static  Connection ConnectDb(){
        
        try {
            Class.forName("com.mysql.jdbc.Driver");
            Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/plot","root","");
            
            JOptionPane.showMessageDialog(null, "cool ConnectionDB");

            return conn;
        } catch (Exception e) {
            
             JOptionPane.showMessageDialog(null,"ConnectionDB Error" + e);
                
        }
        
        return null;
    
    }
    
}

Create other class in same package and name it plot.java 
Note : Download the jar file of “jfreechart-1.0.19” and add it in Libraries !
