Java code to Generate Rhombus patterns using do-while loop
Java code to Generate Rhombus patterns using do-while loop
In this article, we will discuss the concept of Java code to Generate Rhombus patterns using do-while loop
In this post, we are going to learn how to use do-while loop to write a program for print rhombus and hollow rhombus patterns using given symbol in Java programming language.
Display Rhombus patterns Using do-while loop
Code to print Rhombus pattern using do-while loop
Program 1
This program allows the user to enter the number of rows and symbols then it will display the rhombus pattern using do-while loop in Java programming language
//program to display rhombus star pattern using do while import java.util.Scanner; public class RhombusStar3{//class declaration public static void main(String args[]){//main method Scanner scan=new Scanner(System.in); //create a scanner object for user input System.out.println("Enter the number of rows: "); //Take input from the user int rows=scan.nextInt(); //Store the rows in the rows variable 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 in the ch variable entered by user System.out.print("\n"); int i=1; do{//outer do-while loop int j=1; 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 symbol after space j++; }while(j<=rows); System.out.print("\n");//move to next line i++; }while(i<rows); } }
When the above code is executed, it produces the following result
Code to print Hollow Rhombus pattern using do-while loop
This program allows the user to enter the number of rows and symbols then it will display the hollow rhombus pattern using do-while loop in Java programming language
Program 2
//program to display Hollow rhombus pattern import java.util.Scanner; public class HolloWRhombusStarpat{//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: "); //Takes input from the user int rows=scan.nextInt(); //Store the number of rows in rows variable entered by user System.out.println("Enter character as you wish: "); //Ask input from the user as character char ch=scan.next().charAt(0); //Store the character in the ch variable entered by user System.out.print("\n"); int i=1; do{//outer for loop int j=0; do{//inner for loop System.out.print(" ");//print space j++; } while(j<=rows-i); j=1; do{//inner for loop if(i==1 || i==rows || j==1 || j==rows){ //Check the condition, when it is true //When it is false, The control moves to else part System.out.print(ch);//print symbol after space } else{ System.out.print(" ");//print space } j++; }while(j<=rows); System.out.print("\n");//move to next line ++i; }while(i<=rows); } }
When the above code is executed, it produces the following result
