How to join data of two vectors efficiently in java me?

Question

I have two Vectors in my program and I want to join their data

Vector a=new Vector();
Vector b=new Vector();

Answer 1

Vector a = new Vector();
Vector b = new Vector();

// populate vectors a and b
// ...

Vector c = new Vector();

for(Enumeration e = a.elements(); e.hasMoreElements();) {
    c.addElement(e.nextElement());
}
for(Enumeration e = b.elements(); e.hasMoreElements();) {
    c.addElement(e.nextElement());
}

// c now contains all elements from a followed by all elements from b
