How to create an array from different enum elements

Question

public enum CostData {
    IMPRESSIONS("Impressions", "Impressions"),
    CLICKS("Clicks", "Clicks"),
    COST("Expenditure", "Cost"),
    CONVERSION("Conversion", "Conversions");

    private String value1;
    private String value2;

    private CostData(String value1, String value2) {
        this.value1 = value1;
        this.value2 = value2;

    }

    public String getValue1() {
        return value1;
    }

    public String getValue2() {
        return value2;
    }
}

I need to create an array with Impressions, Clicks, Expenditure and Conversion, the first element in each enum element, another array with the second set in each enum element. Any suggestions?

If I understand correctly what you want to do is:

List<String> firstArray = new ArrayList<String>();
List<String> secondArray = new ArrayList<String>();
for(CostData c : CostData.values()) {
    firstArray.add(c.getValue1());
    secondArray.add(c.getValue2());
}

If I get it right you should be doing this.

    int length = CostData.values().length;
    String[] firstArray = new String[length];
    String[] secondArray = new String[length];
    int idx = 0;
    for(CostData cd: CostData.values()){
        firstArray[idx] = cd.getValue1();
        secondArray[idx++] = cd.getValue2();
    }
