How do you write a simple JAVA program to print the letter A in asterisks?

Answer 1

/**

* Prints a pyramid of asterisks of the specified height.

*

* Will print in the form: printStars(3) =

*

***

*****

*/

public static final void printStars(final int height) {

// perform calculations once

final int totalLength = (height * 2) - 1;

final int totalLength_2 = totalLength / 2;

StringBuilder str = new StringBuilder(totalLength);

// fill with spaces

for (int i = 0; i < totalLength; ++i) {

str.append(' ');

}

// fill in levels

for (int i = 0; i <= totalLength_2; ++i) {

str.setCharAt(totalLength_2 + i, '*');

str.setCharAt(totalLength_2 - i, '*');

System.out.println(str);

}

}

/**

* Prints a pyramid of asterisks of the specified height.

*

* Will print in the form: printStars(3) =

*

* *

* *

*/

public static final void printStars(final int height) {

// perform calculations once

final int totalLength = (height * 2) - 1;

final int totalLength_2 = totalLength / 2;

StringBuilder str = new StringBuilder(totalLength);

// fill with spaces

for (int i = 0; i < totalLength; ++i) {

str.append(' ');

}

// fill in levels

for (int i = 0; i <= totalLength_2; ++i) {

if ((totalLength_2 + i - 1) >= 0) {

str.setCharAt(totalLength_2 + i - 1, ' ');

}

if ((totalLength_2 - i + 1) < totalLength) {

str.setCharAt(totalLength_2 - i + 1, ' ');

}

str.setCharAt(totalLength_2 + i, '*');

str.setCharAt(totalLength_2 - i, '*');

System.out.println(str);

}

} OR second method and easier package javaapplication12; /**

*/

public class Main {

public static void main(String[] args) {

for(int i=0; i<5; i++){

for(int v=0;v<i; v++){

System.out.print("*");

}

System.out.println();

}

}

}

Answer 2

//program to display to trangle of stars.

class Startrangle

{

public static void main(String args[])

{

String str="*",space="";

int i,j;

int imax,jmax;

imax=jmax=20; // you can change this value for maximize you trangle(these are number of steps of trangle)

for(i=1;i<=imax;i++)

{

for(j=jmax;j>=1;j--)

{

space=space.concat(" ");

}

System.out.println(space+str);

str=str.concat("**");

jmax--;

space="";

}

}

}

Source Code ::

import java.io.*;
class DiamondStar
{
protected static void main(String args[])throws IOException
{
BufferedReader in=new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the limit");
int a=Integer.parseInt(in.readLine()),b,c,d,e,f,g,h=--a;
for(b=0;b<=a;b++)
{
System.out.println();
for(c=a;c>b;c--)
{
System.out.print(" ");
}
for(d=0;d<=b;d++)
{
System.out.print("* ");
}
}
for(e=0;e{
System.out.println();
for(f=0;f<=e;f++)
{
System.out.print(" ");
}
for(g=f;g<=h;g++)
{
System.out.print("* ");
}
}
}
}

Answer 5

//By Jithin

import java.util.Scanner;

public class Squre {

int i,j,nstar,ndig;

public Squre(){

i=0;

j=0;

nstar=0;

ndig=0;

}

void display(Squre s){

int k=1;

for(i=0;i<s.nstar;i++){

System.out.print("*");

for(j=1;j<s.nstar-1;j++){

if((i>0)&&(i<s.nstar-1)){

System.out.print(" ");

}

else{

System.out.print("*");

}

}

System.out.print("*");

System.out.println();

}

}

public static void main(String args[]){

Scanner sc=new Scanner(System.in);

Squre s=new Squre();

System.out.println("Enter the number of stars int the squares");

s.nstar=sc.nextInt();

s.display(s);

}

}

Answer 6

// diamond shape asterisks

int sp=4; // for spaces

for(int r = 1; r <= 9; r += 2)

{

for(int i = 1; i <= sp ; i++)

System.out.print(" ");

for(int c= 1; c <= r; c++)

{

System.out.print("*");

}

System.out.println();

--sp;

}

int space = 1;

for(int r = 7; r >= 1; r -= 2)

{

for(int i = 1;i <= space; i++)

System.out.print(" ");

for(int c =1;c <= r; c++)

System.out.print("*");

System.out.println();

space++;

}

Answer 7

first draw a pyramid and put stars on that simple ho gaya:p

Answer 8

This one is the simplest way to Print it :

class Printer {

public static void main(String [] divyansh){

System.out.println("*A*");

}

}
