Java

• You create the array a with some values
• You create the Obj object
• You call Obj.cool passing in the array
• Obj.cool calls Second_Arra which sets all the values to 100
• Obj.cool next calls First_Array which sets all the values to 10
• You print the contents of the array

public class ArrayDemo
{
	public static void main(String[] args){
				
			int  a = 5;
			
			Try_Array Obj =new Try_Array();
 
			Obj.cool(a);
			
			System.out.println("A value After Calling:");
			
			 
	
				System.out.print(a );
			}
		 
 
}

public class Try_Array
{
    
    public   void cool(  int a)
    {
        
           First_Array(a);
    	Second_Arra(a);
      
         
    }
 
    
    private   void First_Array(int a )
    {
        a=4;
        
        
 
    }
 
    private   void Second_Arra(int  a )
    {
    	  a=6;
    }
	 
}

A value After Calling:
5

I have also creted classes that are objects such as Layer.java, Neuron.java and Weight.java. I will rewrite my code so that I use these classes as Layer[], Neuron[] and Weight[] instead of double[] and int[].

I find generic List is rather hard to use in java cos of the compiler can't recognize the type etc...from what I have read.

public class subjectDAOImpl implements subjectDAO {
	
	private final String INSERT_QRY1 = "INSERT INTO project.subject subject VALUES (?)";

<pre>public void insertSubject(subject s) throws MyDataException { 
		try {	
			s = new subject();
			ArrayList<String>subj;
			openConnection();			
			String qry = INSERT_QRY1;				
	        ps = connection.prepareStatement(qry);

Controller :
<pre>

try{				
subject m = new subject();			
ArrayList<String>subj = new ArrayList<String>();
String[] sub =  request.getParameterValues("subject");				
for (String s : sub)
subj.add(s);
