Creating generic arrays in Java

Question

public K[] toArray()
{
    K[] result = (K[])new Object[this.size()];
    int index  = 0;
    for(K k : this)
        result[index++] = k;
    return result;
}
         


        

Answer 1

Ok, this not works K[] result = new K[this.size()];

If you could hold class. Then:

  Class claz;
  Test(Class m) {
     claz = m;
  }

    K[] toArray() { 
K[] array=(K[])Array.newInstance(claz,this.size());
return array;
}
