E F G and H character pattern programs in Java

1.  Character Pattern E in Java

In this program we learn how to print character pattern E using Java Programming language

import java.util.*;
class E
{
  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((i==0||i==n-1||i==n/2)&&(j>0&&j<3*(n/4))||(i!=0&&i!=n-1)&&j==0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }

      }
      System.out.println();
    }
  }
}

Output of pattern E in java

Enter the value of n

2.  Character Pattern F in Java

In this program we study how to display character pattern F using Java Programming language

import java.util.*;
class F
{
  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((i==0||i==n/2)&&(j>0&&j<3*(n/4))||(i!=0)&&j==0)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }

      }
      System.out.println();
    }
  }
}

3.  Character Pattern G in Java

In this program we learn how to display character pattern G using Java Programming language

import java.util.*;
class G 
{
  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(i==0&&(j>0&&j<=3*(n/4))||
          j==0&&(i>0&&i<n-1)||
          i==n-1&&(j>0&&j<n/2)||
          (j==n/2||j==3*(n/4))&&i>3*(n/4)||
          i==3*(n/4)&&(j>=n/2&&j<=3*(n/4)))

        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }

      }
      System.out.println();
    }          
  }
}

Output of pattern G in java

Enter the value of n

4.  Character Pattern H in Java

In this program we study how to print character pattern H using Java Programming language

import java.util.*;
class H
{
  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||j==3*(n/4)||i==n/2&&j<3*(n/4))//if(j==0&&i<n/2||j==0&&i>n/2||j==3*(n/4)&&i<n/2||j==3*(n/4)&&i>n/2||j>0&&j<3*(n/4)&&i==n/2)
        {
          System.out.print("*");
        }
        else
        {
          System.out.print(" ");
        }

      }
      System.out.println();
    }
  }
}
