Usage

From source file:Main.java

public static void main(String[] args) {
    ArrayList<String> arrayList = new ArrayList<String>();

    arrayList.add("2");
    arrayList.add("2");
    arrayList.add("3");
    arrayList.add("4");
    arrayList.add("5");
    arrayList.add("1");
    arrayList.add("2");

    System.out.println(arrayList.contains("2"));

    int index = arrayList.indexOf("4");
    if (index == -1)
        System.out.println("not contain 4");
    else//from w w  w  .  j av a 2  s.  c o  m
        System.out.println("4 at index :" + index);

    int lastIndex = arrayList.lastIndexOf("1");
    if (lastIndex == -1)
        System.out.println("not contain 1");
    else
