Finding an Element in a Sorted Array

 
import java.util.Arrays;

public class Main {
  public static void main(String[] argv) {
    String[] sortedArray = new String[] { "a", "b", "c", "d" };

    int index = Arrays.binarySearch(sortedArray, "c");

    index = Arrays.binarySearch(sortedArray, "e");

    int[] sortedIntArray = new int[] { 1, 2, 3, 5, 7 };

    index = Arrays.binarySearch(sortedIntArray, 6);
  }
}
