How to Use Java to Display Letters with Asterisks

Step-by-Step Guide

1. 1

   Step 1: Use any IDE of Java to do the programming.

   The code remains same for every IDE.
   
   You'll have to work differently for the inheritance thing on different IDE.
   
   Apart from that, you're all good to go. , User inputs no. of rows (size) for the display and the alphabet to display.
   
   The main class determines the corresponding sub-program.
   
   The sub-program executes and displays the output.
   
   The program terminates. , Look at an example to help: import java.util.Scanner; public class Display { static Scanner scr = new Scanner(System.in); static Scanner scrInt = new Scanner(System.in); public static void main(String[] args) { System.out.print("\fEnter no. of rows to display : "); int rows = scrInt.nextInt(); System.out.print("Enter the alphabet to display : "); char ch = scr.next().charAt(0); ch = Character.toUpperCase(ch); System.out.print("\n\n"); switch(ch) { case 'A':
   A obj = new A(rows); case 'B':
   B obj1 = new B(rows); case 'C':
   C obj2 = new C(rows); case 'D':
   D obj3 = new D(rows); case 'E':
   E obj4 = new E(rows); case 'F':
   F obj5 = new F(rows); case 'G':
   G obj6 = new G(rows); case 'H':
   H obj7 = new H(rows); case 'I':
   I obj8 = new I(rows); case 'J':
   J obj9 = new J(rows); case 'K':
   K obj10 = new K(rows); case 'L':
   L obj11 = new L(rows); case 'M':
   M obj12 = new M(rows); case 'N':
   N obj13 = new N(rows); case 'O':
   O obj14 = new O(rows); case 'P':
   P obj15 = new P(rows); case 'Q':
   Q obj16 = new Q(rows); case 'R':
   R obj17 = new R(rows); case 'S':
   S obj18 = new S(rows); case 'T':
   T obj19 = new T(rows); case 'U':
   U obj20 = new U(rows); case 'V':
   V obj21 = new V(rows); case 'W':
   W obj22 = new W(rows); case 'X':
   X obj23 = new X(rows); case 'Y':
   Y obj24 = new Y(rows); case 'Z':
   Z obj25 = new Z(rows); } } } , Here's the program for the alphabet A: public class A { A(int row) { if(row<5) row=5; if(row%2==0) row++; for(int i=0;i<row;i++) { char ch = ' '; for(int j=0;j<row-i;j++) { if(j==row-(i+1)) System.out.print("*"); else System.out.print(" "); } if(i==(row/2)) ch='*'; for(int k=0;k<(i*2)-1;k++) System.out.print(ch); ch=' '; for(int l=0;l<row-i;l++) { if(i==0) continue; if(l==0) System.out.print("*"); else System.out.print(" "); } System.out.print("\n"); } } } , Here's the final look of the project in the IDE and the output.
