# Java Program to Print the Series 11 22 33 44 55 … N

In the previous article we have discussed about Java Program to print Series 8 6 9 23 87 … N

In this article we are going to see how to print the series 11 22 33 44 55 … N by using Java programming language.

## Java Program to Print the Series 11 22 33 44 55 … N

On observing the pattern carefully, we can see

1st number starts from 11, Then the next number is the nth times of the previous number

Example:

 11 22 33 44 55 66 … N

11*1             11*2            11*3            11*4            11*5             11*6                                 11*n

Let’s see different ways to  print the series 11 22 33 44 55 … N

### Method-1: Java Program to Print the Series 11 22 33 44 55 … N By Using For Loop

Approach:

• Create Scanner class object.
• Declare an integer variable say ‘n’ which holds the Nth term of the series
• Prompt the user to enter a number as value of n.
• Let declare a integer variable say ‘number’ and initialize it to 11
• Use a for loop from i=1 to i<=n where the loop is incremented by 1
• Let declare an integer variable say ‘result
• Inside the for loop we will find the value of result = number*i.
• Print the result in the series.

Program:

import java.util.*;
public class Main
{
public static void main(String [] args)
{
//creating object of Scanner class
Scanner s = new Scanner(System.in);
//Taking input of number of elements in the series
System.out.println("Enter the Nth term “N” ");
int n = s.nextInt();
int number = 11;
//for loop to print the series
for (int i = 1; i <= n; i++)
{
int result = number*i;
System.out.print(result+" ");
}
}
}

Output:

Enter the Nth term “N”

11 22 33 44 55

### Method-2: Java Program to Print the Series 11 22 33 44 55 … N By Using While Loop

Approach:

• Create Scanner class object.
• Declare an integer variable say ‘n’ which holds the Nth term of the series
• Prompt the user to enter a number as value of n.
• Let declare a integer variable say ‘number’ and initialize it to 11
• Declare and initialize an integer variable i=1
• Continue a while loop till i<=n, where i is incremented by 1.
• Declare an integer variable ‘result
• Inside while loop find the value of result = number*i
• Print the result in the series.

Program:

import java.util.*;
public class Main
{
public static void main(String [] args)
{
//creating object of Scanner class
Scanner s = new Scanner(System.in);
//Taking input of number of elements in the series
System.out.println("Enter the Nth term “N” ");
int n = s.nextInt();
int number=11;
int i=1;
while(i<=n)
{
int result =number*i;
System.out.print(result+"  ");
i++;
}
}
}
Output:

Enter the Nth term “N”

11 22 33 44 55 66 77

### Method-3: Java Program to Print the Series 11 22 33 44 55 … N By Using For Loop

Approach:

• Create Scanner class object.
• Declare an integer variable say ‘n’ which holds the Nth term of the series
• Prompt the user to enter a number as value of n.
• Call a user defined method printSeries() by passing n as parameter.
• Inside method declare a integer variable say ‘number’ and initialize it to 11
• Use a for loop from i=1 to i<=n where the loop is incremented by 1
• Let declare an integer variable say ‘result
• Inside the for loop we will find the value of result = number*i.
• Print the result in the series.

Program:

import java.util.*;
public class Main
{
public static void main(String[] args)
{
// creating object of scanner class
Scanner s = new Scanner(System.in);
//Taking input of number of elements in the series
System.out.println("Enter the value of Nth term 'N' ");
int n = s.nextInt();
// calling printSeries method to print the series
printSeries(n);
}

//printSeries metthod to print the series
public static void printSeries(int n)
{
int number = 11;
//for loop to print the series
for (int i = 1; i <=n; i++)
{
int result =number*i;
System.out.print(result+" ");
}
}
}

Output:

Enter the value of Nth term 'N'
