Get first and last element of an array in Java

1. Get first and last element of a String array

Java program to get the first and last element of a String array is given below:

 public class FirstLastElementArray {
    public static void main(String args[]) {
      // Given string array
      String[] str = new String[]{"Alive","is", "Awesome"};
      // Getting first element of a string array
      String first = str[0];
      // Getting last element of a string array
      String last = str[str.length -1];
      // Print first element of a string array
      System.out.println("First element is: "+first);
      // Print last element of a string array
      System.out.println("Last element is: "+last);
    }
}

Output:
First element is: Alive
Last element is: Awesome

2. Get first and last element of an Integer array

Java program to get the first and last element of an Integer array is given below:

 public class FirstLastElementArray2 {
    public static void main(String args[]) {
      // Given array
      Integer[] numbers = new Integer[]{12, 34, 23, 65, 99};
      // Getting first element of an array
      Integer first = numbers[0];
      // Getting last element of an array
      Integer last = numbers[numbers.length -1];
      // Print first element of an array
      System.out.println("First element is: "+first);
      // Print last element of an array
      System.out.println("Last element is: "+last);
    }
}

Output:
First element is: 12
Last element is: 99
