Generate Double pyramid number pattern in Java
Generate Double pyramid number pattern in Java
In this tutorial, we will discuss a simple concept of the Generate double pyramid number pattern in Java programming language.
In this post, we will learn how to create different types of integrated pyramid number patterns in Java.
we can use for loop, while loop or do while loop to display different integrated pyramid number patterns.
Here, we will use for loop to print different integrated pyramid number patterns
Program 1
Generate Integrated pyramid number pattern 1
import java.util.Scanner;
class DoublePyramid1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number of rows\n");
int rows=scan.nextInt();//reads rows from user
for(int i=1; i<=rows; i++){ //print upper part
for(int j=i; j<=rows; j++){
System.out.print(j+" ");//print number with space }
}
System.out.println();//move to next line
}
for(int i=rows-1; i>=1; i--){ //print lower part
for(int j=i; j<=rows; j++){
System.out.print(j+" ");//print number with space
}
System.out.println();//move to next line
}
}
}
When the above code is executed, it produces the following result
Enter the number of rows 6 1 2 3 4 5 6 2 3 4 5 6 3 4 5 6 4 5 6 5 6 6 5 6 4 5 6 3 4 5 6 2 3 4 5 6 1 2 3 4 5 6
Program 2
Generate Integrated pyramid number pattern 2
import java.util.Scanner;
class DoublePyramid3{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number of rows\n");
int rows=scan.nextInt();//reads rows from user
for(int i=rows; i>=0; i--){ //print upper part
for(int j=1; j<=i; j++){
System.out.print(j+" ");//print number with space
}
System.out.println();//move to next line
}
for(int i=1; i<=rows; i++){ //print lower part
for(int j=1; j<=i; j++){
System.out.print(j+" ");//print number with space
}
System.out.println();//move to next line
}
}
}
When the above code is executed, it produces the following result
Enter the number of rows 6 1 2 3 4 5 6 1 2 3 4 5 1 2 3 4 1 2 3 1 2 1 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6
Program 3
Generate Integrated pyramid number pattern 3
import java.util.Scanner;
class DoublePyramid2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();//reads rows from user
for(int i=1; i<=rows; i++){ //print upper part
for(int j=1; j<=i; j++){
System.out.print(" ");
}
for(int k=i; k<=rows; k++){
System.out.print(k+" ");//print number with space
}
System.out.println();
}
for(int i=rows-1; i>=1; i--){ //print lower part
for(int j=1; j<=i; j++){
System.out.print(" ");//print space
}
for(int k=i; k<=rows; k++){
System.out.print(k+" ");//print number with space
}
System.out.println();
}
}
}
When the above code is executed, it produces the following result
Enter the number of rows: 6
1 2 3 4 5 6
2 3 4 5 6
3 4 5 6
4 5 6
5 6

4 5 6
3 4 5 6
2 3 4 5 6
1 2 3 4 5 6
Program 4
Generate Integrated pyramid number pattern 4
import java.util.Scanner;
class DiamondNumber4{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();//reads rows from user
for(int i=1; i<=rows; i++){ //print upper part
for(int j=1; j<i; j++){
System.out.print(" ");//print space
}
for(int j=i; j<=rows; j++){
System.out.print(j);
}
System.out.println();
}
for(int i=rows-1; i>=1; i--){
for(int j=1; j<i; j++){
System.out.print(" ");//print space
}
for(int j=i; j<=rows; j++){ //print lower part
System.out.print(j);//print number
}
System.out.println();//move to next line
}
}
}
When the above code is executed, it produces the following result
Enter the number of roes: 6
123456
23456
3456
456
56
6
56
456
3456
23456

Generate double pyramid number pattern 5
import java.util.Scanner;
class DoublePyramid4{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number of rows: ");
int rows=scan.nextInt();//reads rows from user
for(int i=1; i<=rows; i++){ //print upper part
for(int j=1; j<=rows-i; j++){
System.out.print(" ");
}
for(int k=1; k<=i; k++){
System.out.print(k+" ");//print number with space
}
System.out.println();
}
for(int i=1; i<=rows-1; i++){ //print lower part
for(int j=1; j<=i; j++){
System.out.print(" ");
}
for(int k=1; k<=rows-i; k++){
System.out.print(k+" ");//print number with space
}
System.out.println();
}
}
}
When the above code is executed, it produces the following result
Enter the number of rows: 6
