Parallelogram star pattern program in Java language using loops

In this article, we will discuss the Parallelogram star pattern program in Java language

We can display many types of number, star, Alphabet, Binary patterns using for.while and do-while loop in Java language

In this post, we are going to learn how to print Parallelogram star pattern using for, while and do-while loop in Java language,

Note – Here,To create this pattern , you can use either star or any symbol as you wish

Code to display Parallelogram star pattern using for loop

This program allows the user to enter the number of rows,columns and any character or symbols then the program displays the Parallelogram star pattern using for loop in Java language

Program 1

//program to print parallelogram star pattern
import java.util.Scanner;
public class parallelogramStar1{//class declaration
public static void main(String args[]){//main method

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the number of rows: ");
//Ask input from the user to rows
int rows=scan.nextInt();
//Store the rows entered by user

System.out.println("Enter the number of columns: ");
//Ask input from the user to columns
int columns=scan.nextInt();
//Store the columns entered by user

System.out.println("Enter Symbol as you wish: ");
//Ask input from the user as symbol
char ch=scan.next().charAt(0);
//Store the symbol entered by user

System.out.print("\n");
for(int i=1; i<=rows; i++){//outer for loop 
   for(int j=1; j<=rows-i; j++){//inner for loop
   System.out.print(" ");//print space
   }
   for(int j=1; j<=columns; j++){//inner for loop
   System.out.print(ch);//print symbol after space
}
 System.out.print("\n");//move to next line
}
}
}

When the above code is executed, it produces the following result

Code to display Parallelogram character pattern using while loop

This program allows the user to enter the number of rows, columns and any character or symbols then the program displays the Parallelogram character pattern using while loop in Java language

Program 2

//program to print parallelogram star pattern
import java.util.Scanner;
public class parallelogramStar2{//class declaration
public static void main(String args[]){//main method

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input
  
System.out.println("Enter the number of rows: ");
//Ask input from the user to rows
int rows=scan.nextInt();
//Store the rows entered by user

System.out.println("Enter the number of columns: ");
//Ask input from the user to columns
int columns=scan.nextInt();
//Store the columns entered by user

System.out.println("Enter Symbol as you wish: ");
//Ask input from the user as symbol
char ch=scan.next().charAt(0);
//Store the symbol entered by user

System.out.print("\n");
int i=1;
while(i<=rows){//outer while loop 
int j=1; 
   while(j<=rows-i){//inner while loop
   System.out.print(" ");//print space
   j++;
   }
   j=1;
   while(j<=columns){//inner while loop
   System.out.print(ch);//print character after space
    j++;
}
 System.out.print("\n");//move to next line
  i++;
}
}
}

When the above code is executed, it produces the following result

Code to display Parallelogram number pattern using do-while loop

This program allows the user to enter the number of rows , columns and any character or symbols then the program displays the Parallelogram number pattern using do-while loop in Java language

Program 3

//program to print parallelogram star pattern
import java.util.Scanner;
public class parallelogramStar3{//class declaration
public static void main(String args[]){//main method

 Scanner scan=new Scanner(System.in); 
  //create a scanner object for input

//Ask input from the user to rows
int rows=scan.nextInt();
//Store the rows entered by user

System.out.println("Enter the number of columns: ");
//Ask input from the user to columns
int columns=scan.nextInt();
//Store the columns entered by user

System.out.println("Enter Symbol as you wish: ");
//Ask input from the user as symbol
char ch=scan.next().charAt(0);
//Store the symbol entered by user

System.out.print("\n");
int i=1;
do{//outer do-while loop 
int j=0; 
do{//inner do-while loop
   System.out.print(" ");//print space
   j++;
   }while(j<=rows-i);
   j=1;
   do{//inner do-while loop
   System.out.print(ch);//print character after space
    j++;
}while(j<=columns);
 System.out.print("\n");//move to next line
  i++;
}while(i<=rows);
}
}
