🚀 Programming Example
Deletion from End (Java Program)
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
import java.util.Scanner;
public class DeleteFromEnd {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int[] arr = new int[100];
int n, i;
System.out.print("Enter number of elements: ");
n = sc.nextInt();
System.out.println("Enter elements:");
for(i = 0; i < n; i++) {
arr[i] = sc.nextInt();
}
// delete last element
n--;
System.out.println("Array after deletion from end:");
for(i = 0; i < n; i++) {
System.out.print(arr[i] + " ");
}
}
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
