Java code to reverse order triangle number patterns

In this tutorial, we will discuss Java code to reverse order triangle number patterns. We will see some reverse Floyd’s triangle number patterns, using nested for loop.

Floyd’s triangle number pattern

Pattern program 1

Java code to reverse order triangle number patterns — Floyd’s triangle reserved pattern

import java.util.Scanner; 
public class RevNum_pattern1{
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=i; j>=1; j--){
  
   System.out.print(j);

}
System.out.println();

}
}
}

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

Enter the rows you want :8
1
21
321
4321
54321
654321
7654321
87654321

In this Floyd’s triangle pattern, numbers are arranged to reverse order in every line – used nested for loop

Pattern program 2

import java.util.Scanner; 
public class RevNum_pattern2{
public static void main(String args[]){
Scanner sc=new Scanner(System.in); //Scanner class in java
System.out.print("Enter the number of rows you want");
int rows=sc.nextInt();
System.out.println("");

while(rows>=1){
    int j=rows;
    while(j>=1){
        System.out.print(j);
        j--;
    }
    rows--;
    System.out.println();
}


}
}

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

Enter the number of rows you want:6
654321
54321
4321
321
21
1

Pattern program 3

import java.util.Scanner; 
public class RevNum_pattern3{
public static void main(String args[]){
Scanner sc=new Scanner(System.in); //Scanner class in java
System.out.print("Enter the number of rows you want");
int rows=sc.nextInt();
System.out.println("");

while(rows>=1){
    int j=8;
    while(j>=rows){
        System.out.print(j);
        j--;
    }
    rows--;
    System.out.println();
}


}
}

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

Enter the number of rows you want: 8
8
87
876
8765
87654
876543
8765432
87654321

Pattern program 4

import java.util.Scanner; 
public class RevNum_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("");

while(rows>0){
for (int i=1; i<=rows; i++){
  
   System.out.print(rows);
}
System.out.println(" ");
rows--;
        }
     }
}

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

Enter the rows you want: 9
999999999
88888888
7777777
666666
55555
4444
