Returns the index of the first occurrence of the specified element in this list, or -1 if this list does not contain the element.

Usage

From source file:Main.java

public static void main(String[] args) {
    LinkedList<String> lList = new LinkedList<String>();
    lList.add("1");
    lList.add("2");
    lList.add("3");
    lList.add("4");
    lList.add("5");
    lList.add("2");

    System.out.println(lList.indexOf("2"));

    System.out.println(lList.lastIndexOf("2"));

}
