Vector into Array

[J. Alenis]

I would like to know if it is possible and how to do the following. I get a created Vector and I need to put it into an Array. Here are pieces of my program:

String [] columnName ={"sqlcode","sqlmessage","predicaat"};
String [] columnIO ={"out","out","in"};
String [] columnType ={"integer","varchar","varchar"};
Object [] columnValue ={"","","'nn>''123456789010'''"};

Vector in = new Vector();
for (int i=0; i<columnName.length;++i)
{ Vector row = new Vector();
row.addElement(columnName[i]);
row.addElement(columnIO[i]);
row.addElement(columnType[i]);
row.addElement(columnValue[i]);
in.addElement(row);
}

And I want all the elements in an array that will look like this:

String[][]SP_parms = {{"Out","integer","sqlcode","0"},
{"In","varchar","predicaat","'nn>''123456789010'''"},
{"Out","varchar","sqlmessage",""} };
Can somebody please help me.

If you can consider something else instead of the Vector you'd gain performance, but that aside.
calling "in.toArray" will result in an array of Vector objects, each with its own set of elements, now calling "row.toArray" on each of them will result in an Object[] again only this time it's your Strings, you can initialise a new array based on the number of rows you have, and loop to add its array.
Did I misunderstand you?

The problem is that I receive the Vector like it is (I can't change annything) and I want these data to be moved into the table like I showed in my question.
Do I have to use StringTokenizer to get every element to move in a field in the table?

no I don't see how StringTokenizer can be used here, you already have all the elements/tokens/Strings setup individually in that vector, why not just iterate through them?

Given vector "v" create an array "copyV" and copy the contents of your vector into it. Pretty straightforward stuff. Assuming, of course, that you want the contents of the array converted from objects to strings (which was the case for my application).

Hopefully this will at least provide some direction.


copyV = new String[v.size()];
v.copyInto(copyV);

try this:

String[][] resultArray=new String[in.size()][];
Vector[] tmp=new Vector[in.size()];
in.toArray(tmp);
for (int i=0,len=tmp.length;i<len;i++)
{
resultArray[i]=new String[tmp[i].size()];
tmp[i].toArray(resultArray[i]);
}

Thanks J�rg Vater,

This is what I really needed.
