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

Are you a job seeker and trying to find simple java programs for Interview? This would be the right choice for you, just tap on the link and start preparing the java programs covered to crack the interview.

Approach:

  • Enter total row and store it in an integer variable row.
  • Take first for loop to print the row value and a star for each row.
  • Take first inner for loop to print column value i.e., star according to condition
    if ((r == 0) || (r == row / 2  && c <= row / 2))
  • Then go on printing the star symbol according to loop.

JAVA Code:

Method-1 : Static Star Character

import java.util.*;

public class Main 
{    
    public static void main(String args[])   
    {   
    // taking variable for loop iteration and row .
    int row,r,c,d;
    
    //creating object 
    Scanner s = new Scanner(System.in);
    
    // entering the number of row
    System.out.print("Enter rows : ");
    row = s.nextInt();
    
    //outer for loop 
    for (r = 0; r < row; r++) 
    {
        System.out.print("*");
        // inner for loop
        for (c = 0; c < row; c++)
        {
            // printing star
            if ((r == 0) || (r == row / 2 && c <= row / 2))
                System.out.print("*");
            // printing space
            else
                continue;
        }
        System.out.print("\n");
    }
    }
}

Output :

Enter row :  5

Method-2 : User Input Character

import java.util.*;

public class Main 
{    
    public static void main(String args[])   
    {   
    // taking variable for loop iteration and row .
    int row,r,c,d;
    char f;
    
    //creating object 
    Scanner s = new Scanner(System.in);
    
    // entering the number of row
    System.out.print("Enter rows : ");
    row = s.nextInt();
    
    // entering any random character
    System.out.print("Enter character : ");
    f = s.next().charAt(0);
    
    //outer for loop 
    for (r = 0; r < row; r++) 
    {
        System.out.print(f);
        // inner for loop
        for (c = 0; c < row; c++)
        {
            // printing star
            if ((r == 0) || (r == row / 2 && c <= row / 2))
                System.out.print(f);
            // printing space
            else
                continue;
        }
        System.out.print("\n");
    }
    }
}

Output :

Enter row :  5 
Enter character : #

######
#
####
#

C Code:

#include <stdio.h>
int main() {
   int r, row, c ,d;
   printf("Enter rows: ");
   scanf("%d", &row);
   for (r = 0; r < row; r++) 
    {
         printf("*");
        for (c = 0; c < row; c++)
        {
            if ((r == 0) || (r == row / 2 && c <= row / 2))
               printf("*");
            else
                continue;
        }
         printf("\n");
    }
   return 0;
}
Output :

Enter row :  5

C++ Code:

#include <iostream>
using namespace std;
int main()
{
   int row, r , c ,d ;
   cout << "Enter  rows: ";
   cin >> row;
    for (r = 0; r < row; r++) 
    {
        cout << "*";
        for (c = 0; c < row; c++)
        {
            if ((r == 0) || (r == row / 2  && c <= row / 2))
                cout << "*";
            else
                continue;
        }
        cout << "\n";
    }
   return 0;
}

Output :

Enter row :  5
