Thread: Alternating Numbers Of two sequences

I am trying to alternate the numbers of two Sequences. Right now getting an infinite loop.
any suggestions? Here is my method.

public ArrayList<Integer> merge (Sequence other)
{
for (int i =0; i < other.values.size(); i++)
{
if (i%2==0)
{

for (int j =0; j < values.size(); j++)
{
other.values.add(i, values.get(j));


}
}

}

return other.values;
}

Can you please explain

trying to alternate the numbers of two Sequences

and what's the structure of Sequence Class.

The Following is my sequence class. I have two Sequences. I am passing the other sequence into the merge method . I am using modulo and an if statement insert at each even iteration of the elements of the first sequence. Right now I am getting an infinite loop and am not sure of where to go from here.




public class Sequence {

private ArrayList <Integer> values;

public Sequence ()
{
values= new ArrayList <>();
}
/**
*
* @param n
*/
public void add (int n)
{
values.add (n);
}
/**
*
* @return
*/
public String toString()
{
return values.toString();
}
/**
*
* @param other
* @return
*/
public ArrayList<Integer> append (Sequence other)
{
for (Integer value : other.values)
{
this.values.add(value);
}
return values;
}

/**
*
* @param other
* @return
*/
public ArrayList<Integer> merge (Sequence other)
{
for (int i =0; i < other.values.size(); i++)
{
if (i%2==0)
{

for (int j =0; j < values.size(); j++)
{
other.values.add(i, values.get(j));


}
}

}

return other.values;
}

}


In the main method I have the following:

Sequence firstLine = new Sequence();
Sequence secondLine = new Sequence ();

firstLine.add(1);
firstLine.add(4);
firstLine.add(9);
firstLine.add(16);

secondLine.add(9);
secondLine.add(7);
secondLine.add(4);
secondLine.add(9);
secondLine.add(11);
firstLine.append(secondLine);
firstLine.toString();
System.out.println(firstLine);
firstLine.merge(secondLine);
System.out.println(firstLine);

Correction:
The Following is my sequence class. I have two Sequences. I am passing the "other" sequence into the merge method . I am using modulo and an if statement to insert at each even iteration the elements of the first sequence. Right now I am getting an infinite loop and am not sure of where to go from here.

So far these are my changes to the method.

 
public String merge (Sequence other)
  { 
        for (int i =0; i < other.values.size(); i++)  
        {  // System.out.println("change");
            //System.out.println("pos" + pos + "i" + i );
 
 
            if ( i%2==0 && pos<=3)
            {   
 
                list = list + values.get(i)+ DEL;
                list= list + other.values.get(pos)+ DEL; 
                //System.out.println("seqOne " + list);
            }
 
            if ( i%2==1&& pos<=3 )
            {   
                list = list + values.get(i)+ DEL; 
                list= list + other.values.get(pos)+ DEL;
 
                 // System.out.println("seq2 " + list);
            }
 
            if ( i%2==0 && pos==4)
            {   
 
 
                list= list + other.values.get(pos); 
               // System.out.println("seqOne " + list);
            }
 
 
            pos++;
 
 
 
           /* if (i%2==0)
            {    
                  other.values.add(i, values.get(pos));
 
                pos++;
            }
                   */
 
  }return list;
 
}}
