Usage

From source file:Main.java

public static void main(String[] args) {
    String[] colours = { "Red", "Orange", "Yellow", "Green", "Blue", "Violet", "Orange", "Blue" };

    boolean contains = ArrayUtils.contains(colours, "Blue");
    System.out.println("Contains Blue? " + contains);

    int indexOfYellow = ArrayUtils.indexOf(colours, "Yellow");
    System.out.println("indexOfYellow = " + indexOfYellow);
    int indexOfOrange = ArrayUtils.indexOf(colours, "Orange");
    System.out.println("indexOfOrange = " + indexOfOrange);
