Element Access: Retrieving Values from Arrays

Easy

Problem Description

Array Element Access

Array elements are accessed using indices (subscripts).

Basic Access

int[] arr = {10, 20, 30, 40, 50};
System.out.println(arr[0]); // 10 (first element)
System.out.println(arr[2]); // 30 (third element)
System.out.println(arr[4]); // 50 (last element)

Learning Points

  • Index starts from 0
  • Last element index is array length - 1
  • Out-of-bounds access causes errors
.
