Example:

When row Size :    5
                     F
                  EF
              DEF

     BCDEF
          CDEF
               DEF
                    EF
                        F

Now, let’s see the actual program to print it.

Provided list of Simple Java Programs is specially designed for freshers and beginners to get familiarize with the concepts of Java programming language and become pro in coding.

Approach:

Enter size and store it in an integer variable size.
Take first for loop to print all rows.
Take second/inner for loop to print column values.
Then go on printing the characters according to the iteration.

Java Code to print Arrow Character Pattern

import java.util.Scanner;
class Main
{
    public static void main(String[] args)  
    {  
        int r, c,k;
        // starting ASCII value taken 65
        int ascii=65;
        Scanner scan = new Scanner(System.in);
        System.out.print("Size : ");
        //Taking size as input from user
        int size=scan.nextInt();
      
     //Outer for loop  
    for (r = -size; r <= size; r++)
    {
        k = r;
        //To calculate the number of characters printed
        if (k < 0)
        {
            k *= -1;
        }
        //Inner Loop to print character and space
        for (c = 0; c <= size; c++)
        {
            if (c < k)
                //printing space
                System.out.print("  ");
            else
                //printing character
                System.out.print((char)(c+ascii));
        }
        System.out.println();
        
    }
}
}

Output:

Size :    5       
                       F
                   EF
              DEF
         CDEF
     BCDEF
ABCDEF
     BCDEF
          CDEF
               DEF
                   EF
                      F

C++ Code to print Arrow Character Pattern

#include <iostream>
using namespace std;
int main(int argc, char const *argv[])
{  
    int size, r, c, k;
    // starting ASCII value taken 65
    int ascii=65;
    
    cout << "Size : ";
    //Taking size as input from user
    cin >> size;
    for (r = -size; r <= size; r++)
    { //inner loop
        k = r;
        if (k < 0)
        { //To calculate the number of stars printed
            k *= -1;
        }
        for (c = 0; c <= size; c++)
        { //Inner Loop to print star and space
            if (c < k)
                cout << "  ";
            else
                cout << (char)(c+ascii);
        }
        //Prints a new line
        cout << endl;
    }
    return 0;
}

Output:

Size :      5
  
                        F
                    EF
               DEF
          CDEF
     BCDEF
ABCDEF
     BCDEF
          CDEF
               DEF
                    EF
                       F
