Filed under:
public class TestClass{


private String divisions[] ={};


public void doAction(){

 Collection testArray = new ArrayList();
 // put testArray will data

  divisions = (String [] )  testArray.toArray(division);    //should i use this
 divisions = (String [] )  testArray.toArray(new String [] {});   //should i use this?

}

}

if i use case 1, and i call doaction multiple time, the division, something will show wrong records if i use case2, divisions will always show the correct records. is my assumption should use case 2?
