M N O and P character pattern programs in Java 

In this series of tutorial, we will study how to print character pattern programs in java. In this post, we will see how to create pattern M, N, O, and P in Java.

1.  Character Pattern M in Java

This program demonstrates the process of displaying the pattern M using Java programming language.

import java.util.*;
class M
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==j&&i<n/2||i+j==n-1&&i<n/2||j==n-1&&i>=0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

Output of pattern M in java

Enter the value of n

2.  Character Pattern N in Java

This program demonstrates the process of printing the pattern N using Java programming language.

import java.util.*;
class N
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==j||j==n-1&&i>=0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

Output of pattern N in java

Enter the value of n

3.  Character Pattern O in Java

This program demonstrates the how to display the pattern O using Java programming language.

import java.util.*;
class O
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==0&&j>=0||i==n-1&&j>=0||j==n-1&&i>=0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

Output of pattern O in java

Enter the value of n

4.  Character Pattern P in Java

This program demonstrates the how to print the pattern P using Java programming language.

import java.util.*;
class P
{
  public static void main(String[] args)
  {
    Scanner scan =new Scanner(System.in);
    System.out.println("enter the value of n");
    int n=scan.nextInt();
    for(int i=0;i<n;i++)
    {
      for(int j=0;j<n;j++)
      {
        if(j==0&&i>=0||i==n/2&&j>=0||i==0&&j>=0||j==n-1&&i<=n/2)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }
      }
      System.out.println();
    }
  }
}

Output of pattern P in java

Enter the value of n
