java
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?
