Inverted Pyramid number pattern in Java
In tis tutorial, we will discuss about Inverted Pyramid number pattern in Java
Here we are going to learn about how to create Pyramid pattern in Java
Code to inverted Pyramid pattern 1
Program 1
import java.util.Scanner;
public class Pyramid_pattern4{
public static void main(String args[]){
Scanner sc=new Scanner(System.in); //Scanner class in java
System.out.print("Enter the rows you want");
int rows=sc.nextInt();
System.out.println("");
for (int i=1; i<=rows; i++){
for (int j=1; j<=rows; j++){
System.out.print(" ");
}
rows--;
for (int k=1; k<=i; k++){
System.out.print(i+" ");
}
System.out.println();
}
}
}
When the above code is executed, it produced following result
1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7
1 2 3 4 5
1 2 3

Code to inverted Pyramid pattern 2
Program 2
import java.util.Scanner;
public class Invert_pattern2{
public static void main(String args[]){
Scanner sc=new Scanner(System.in); //Scanner class in java
System.out.print("Enter the rows you want");
int rows=sc.nextInt();
System.out.println("");
for (int i=rows; i>=1; i--){
for (int j=0; j<=rows-i; j++){
System.out.print(" ");
}//print space
int count=0;
while(count != (2*i-1)){
System.out.print(i+"");
count++;
}
System.out.println();
}
}
}
When the above code is executed, it produced following result
99999999999999999
888888888888888
7777777777777
66666666666

Code to inverted Pyramid pattern 3
Program 3
import java.util.Scanner;
public class Invert_pattern3{
public static void main(String args[]){
Scanner sc=new Scanner(System.in); //Scanner class in java
System.out.print("Enter the rows you want: ");
//Taking input(rows value) from user
int rows=sc.nextInt();
System.out.println("");
int count=rows;//initializing count with rows
for (int i=0; i<=rows; i++){
for (int j=1; j<=i*2; j++){
System.out.print(" ");
}//print space at the bigining of each row
for(int j=1; j<=count; j++) {
System.out.print(j+" ");//print left part of pyramid
}
for(int j=count-1; j>=1; j--) {
System.out.print(j+" "); //print right part of pyramid
}
System.out.println();
count--;
}
}
}
When the above code is executed, it produced following result
1 2 3 4 5 6 7 8 9 8 7 6 5 4 3 2 1
1 2 3 4 5 6 7 8 7 6 5 4 3 2 1
1 2 3 4 5 6 7 6 5 4 3 2 1
1 2 3 4 5 6 5 4 3 2 1
1 2 3 4 5 4 3 2 1
1 2 3 4 3 2 1
1 2 3 2 1

Code to inverted Pyramid pattern 4
Program 4
import java.util.Scanner;
public class Reverse_Pyramid{
public static void main(String args[]){
int rows;
Scanner s=new Scanner(System.in);
System.out.println("Enter number of rows");
rows=s.nextInt();
for(int i=1; i<=rows; i++){//do for rows in pyramid
for(int j=1; j<=i; j++){
System.out.print(" ");//print space
}
for(int k=i; k<=rows; k++){
System.out.print(k+" ");
}
System.out.println();
}
}
}
When the above code is executed, it produced following result
1 2 3 4 5 6 7 8
2 3 4 5 6 7 8
3 4 5 6 7 8
4 5 6 7 8
5 6 7 8
6 7 8
