Java code to display diamond star pattern
Java code to display diamond pattern
In this tutorial, we will discuss Java code to display diamond pattern
In this program, we are going to learn how to displayed diamond star pattern using for loop or nested for loop in Java programming language
here, we display a diamond pattern program with coding using nested for loop and also we get input from the user using Scanner class in Java language
the user can provide numbers as they wish and get the diamond star pattern according to their input
Display star pattern using for loop
Diamond star pattern 1
Program 1
import java.util.Scanner; class StarDiamond{ public static void main(String args[]){ int i,j,Num_Of_space=1;; Scanner scan=new Scanner(System.in); System.out.print("Enter the number of rows: "); int rows=scan.nextInt();//get input from user Num_Of_space=rows-1; System.out.print("\nYour pattern here\n\n"); for(i=1; i<=rows; i++){//parent for loop for(j=1; j<=Num_Of_space; j++)// for loop to print space System.out.print(" ");//print space Num_Of_space--; for(j=1; j<=2*i-1; j++) System.out.print("*");//print asterisk System.out.print("\n"); } Num_Of_space=1; for(i=1; i<=rows-1; i++){//parent for loop for(j=1; j<=Num_Of_space; j++)// for loop to print space System.out.print(" ");//print space Num_Of_space++; for(j=1; j<=2*(rows-i)-1; j++)//for loop to print asterisk System.out.print("*");//print asterisk System.out.print("\n"); } } }
When the above code executed, it produces the following results
Enter the number of rows: 6 Your pattern here * *** ***** ******* ********* *********** ********* ******* ***** *** *
Display star pattern using while loop
In this program, we are going to learn how to displayed diamond star pattern using while loop or nested for loop in Java programming language
here, we display a diamond star pattern program with coding using nested while loop and also we get input from the user using Scanner class in Java language
the user can provide numbers as they wish and get the diamond star pattern according to their input
Diamond star pattern 2
Program 2
import java.util.Scanner; class StarDiamond1{ public static void main(String args[]){ Scanner scan=new Scanner(System.in); System.out.print("Enter the number of rows: "); int rows=scan.nextInt(); int space=rows-1; int i=1,j=1; while(j<=rows){//parent wile loop System.out.print("\n");//move to next line j=1; while(j<=space){//while loop for print space System.out.print(" ");//print space j++; } j=1; while(j<=2*i-1){//while loop for printing star System.out.print("*");//print star j++; } i++; space--; } i=rows-1; space=1; while(i>=1){//parent while loop System.out.print("\n"); j=1; while(j<=space){ System.out.print(" ");//print space j++; } j=1; while(j<=2*i-1){ System.out.print("*");//print star j++; } i--; space++; } } }
When the above code executed, it produces the following results
Enter the number of rows: 6 * *** ***** ******* ********* *********** ********* ******* ***** *** *
