i am having a vector. i want to store the first value in the vector as "A", second as "B" and third as "c".
The fourth value should again be set as "a" and so on.
eg
A[0] =vector.elementAt(0);
B[0]=vector.elementAt(1);
c[0]=vector.elementAt(3);
a[1]=vector.elementAt(4);
and so on... Please let me know how to do this.
import java.util.*;
class sortVector
{
public static void main(String args[])
{
Vector vect=new Vector();
vect.add("c");
vect.add("f");
vect.add("k");
vect.add("a");
vect.add("g");
vect.add("z");
System.out.println("Vector before sorting"+vect);
Collections.sort(vect);
System.out.println("Vector before sorting"+vect);
}
}

I am having a vector with values in it. the values have to be assigned
in this manner, depending on the size
a[0] = vector.elementAt[0];
b[0] =vector.elementAt[1];
and so on...where a & b are arrays or strings.
the fourth value from vector is again assigned to a[1].

Your question is confusing. Sorry to say that. Let me ask you this
Are you asking how to distribute the values in vector among three arrays?
if so..
int collSize = vector.size();
arraySize = collSize/3 + 1; //not accurate though, consider size = 10
int[] a = new int[arraySize];
int[] b = new int[arraySize];
int[] c = new int[arraySize];
int aCount = bCunt = cCount = 0;
for each element in vector indexed by i; range 0 to size 1
{
currElement = vector.element at i;
if(i % 3 == 0)
{
a[aCount ++] = currElement;
}
else if (i % 3 == 1)
{
b[bCount ++] = currElement;
}
else
{
c[cCount ++] = currElement;
}
}
arraySize = collSize/3 + 1; //not accurate though, consider size = 10
int[] a = new int[arraySize];
int[] b = new int[arraySize];
int[] c = new int[arraySize];
Below is a solution to compute right array size.
In case of 10 elements you need three arrays with 4, 3, 3 elements respectively
In case of 11 elements you need three arrays with 4, 4, 3 elements respectively
In case of 12 elements you need three arrays with 4, 4, 4 elements respectively
So the ArraySize can be different for all arrays.
Say aArraySize, BArraySize, cArraySize
After dividing the size by 3 you get a fraction,
If this fraction is zero (3/3), aArraySize = bArraySize = cArraySize = size/3;
If this fraction is .33 (1/3) or less than .5
aArraySize = size/3 + 1; bArraySize = cArraySize = size/3;
If this fraction is .66(2/3) or greater than .5
aArraySize = bArraySize = size/3 + 1; cArraySize = size/3;
To find the fraction you can do
fraction = size/3  (int)size/3
