Java code to display alphabet pyramid pattern

Java code to display alphabet pyramid pattern

In this tutorial, we will discuss the concept of Java code to display alphabet pyramid pattern

In this post, we will learn how to displayed  Pyramid triangle alphabet pattern  using for loop or nested for loop in Java programming language

here, we displayed some alphabet pyramid triangle program with coding using nested for loop and also we get input from user using Scanner class in Java language

the user can provide numbers as they wish and get the alphabet pattern according to their input

Program 1

Pyramid triangle alphabet pattern 1

import java.util.Scanner;//import the scanner class
class PyramidPattern2{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);//create a scanner object
System.out.println("Enter the number of rows");
int rows=scan.nextInt();
int i,j;

for(i=1; i<=rows; i++){
   for(j=1; j<=rows-i; j++){
   System.out.print(" ");//print "space" for the initial part of the pyramid 
}
   for(j=1; j<=i; j++){
   System.out.print((char)(j+64));

}
    for(j=i-1; j>=1; j--){
   System.out.print((char)(j+64));

}
System.out.println();
}
}

}

When the above code is executed, it produces the following results

Enter the number of rows
6
          A
        ABA
      ABCBA
    ABCDCBA
  ABCDEDCBA
ABCDEFEDCBA

 

Program 2

Pyramid triangle alphabet pattern 2

import java.util.Scanner;//import the scanner class
class PyramidPattern3{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);//create a scanner object
System.out.println("Enter the number of rows");
int rows=scan.nextInt();
int i,j;

for(i=1; i<=rows; i++){
   for(j=1; j<=rows-i; j++){
   System.out.print(" ");//print "space" for the initial part of the pyramid 
}
   for(j=i; j>0; j--){
   System.out.print((char)(j+64));//print left site of pyramid triangle

}
    for(j=2; j<=i; j++){
   System.out.print((char)(j+64));//print right site of pyramid triangle

}
System.out.println();
}
}

}

When the above code is executed, it produces the following results

Enter the number of rows
6
          A
        BAB
      CBABC
    DCBABCD
  EDCBABCDE
FEDCBABCDEF

 

Program 3

Pyramid triangle alphabet pattern 3

import java.util.Scanner;//import the scanner class
class PyramidPattern4{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);//create a scanner object
System.out.println("Enter the number of rows");
int rows=scan.nextInt();
int i,j;

for(i=1; i<=rows; i++){
   for(j=1; j<=rows-i; j++){
   System.out.print(" ");//print "space" for the initial part of the pyramid 
}
   for(j=1; j<=i; j++){
   System.out.print((char)(char)(j+64)+" ");

}
System.out.println();
}
}

}

When the above code is executed, it produces the following results

Enter the number of rows
5
        A
      A B
    A B C
  A B C D
A B C D E

Program 4

Pyramid triangle alphabet pattern 4

import java.util.Scanner;//import the scanner class
class PyramidPattern4{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);//create a scanner object
System.out.println("Enter the number of rows");
int rows=scan.nextInt();
int i,j;

for(i=1; i<=rows; i++){
   for(j=1; j<=rows-i; j++){
   System.out.print(" ");//print "space" for the initial part of the pyramid 
}
   for(j=1; j<=i; j++){
   System.out.print((char)(char)(i+64)+" ");

}
System.out.println();
}
}

}

When the above code is executed, it produces the following results

Enter the number of rows
6
        A
      B B
    C C C
  D D D D
 E E E E E
F F F F F F

Program 5

Pyramid triangle alphabet pattern 5

import java.util.Scanner;//import the scanner class
class PyramidPattern5{
public static void main(String args[]){
Scanner scan=new Scanner(System.in);//create a scanner object
System.out.println("Enter the number of rows");
int rows=scan.nextInt();
int i,j;

for(i=rows; i>=1; i--){
   for(j=1; j<=rows-i; j++){
   System.out.print("  ");//print "space" for the initial part of the pyramid 
}
   for(j=1; j<=2*i-1; j++){
       if(j<=i)
   System.out.print((char)(char)(j+64)+" ");
else
    System.out.print((char)(char)(2*i-j+64)+" ");

}
System.out.println();
}
}

}

When the above code is executed, it produces the following results

Enter the  number of rows
5
A B C D E D C B A
    A B C D C B A
        A B C B A
            A B A
                A
