Programming Example
Updating Array Elements in java
Study this program carefully to understand the logic, output, and explanation in a structured way.
public class UpdateArray {
public static void main(String[] args) {
int[] arr = {10, 20, 30, 40, 50};
arr[2] = 100; // updating element at index 2
System.out.println("Updated Array: ");
for(int num : arr) {
System.out.print(num + " ");
}
}
}
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
