Programming Example
Traversing an Array in java
Study this program carefully to understand the logic, output, and explanation in a structured way.
public class TraverseArray {
public static void main(String[] args) {
int[] arr = {5, 10, 15, 20, 25};
System.out.println("Using for loop:");
for(int i = 0; i < arr.length; i++){
System.out.print(arr[i] + " ");
}
System.out.println("\nUsing enhanced for loop:");
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.
