One Dimensional Array

title: One Dimensional Array description: 1D array ka detail use aur operations

Create aur Use karna

// Step 1: Declare int[] scores; // Step 2: Create scores = new int[5]; // Step 3: Initialize scores[0] = 85; scores[1] = 92; scores[2] = 78; scores[3] = 95; scores[4] = 88; // Ya ek saath int[] scores = {85, 92, 78, 95, 88};

Important Operations

Sum aur Average

java exampleWoHoTech

int[] nums = {10, 20, 30, 40, 50};
int sum = 0;
for (int n : nums) sum += n;
double avg = (double) sum / nums.length;
System.out.println("Sum: " + sum + ", Avg: " + avg);

Max aur Min dhundhna

int[] arr = {5, 2, 9, 1, 7}; int max = arr[0], min = arr[0]; for (int n : arr) { if (n > max) max = n; if (n < min) min = n; } System.out.println("Max: " + max + ", Min: " + min);

Array Reverse karna

int[] arr = {1, 2, 3, 4, 5}; int left = 0, right = arr.length - 1; while (left < right) { int temp = arr[left]; arr[left] = arr[right]; arr[right] = temp; left++; right--; }

Array Copy

java exampleWoHoTech

int[] original = {1, 2, 3};
int[] copy = Arrays.copyOf(original, original.length);
int[] rangeCopy = Arrays.copyOfRange(original, 1, 3); // {2, 3}
