Question

write a program to print this pattern
plzz hlp I am having my test​

Answer 1

public class DiamondPattern {

public static void main(String[ ] args) {

int columns = 3, spaces = columns - 1;

// The symbol to be printed

char symbol = '*';

// Upper half of the diamond

for (int j = 1; j <= columns; j++) {

// Printing spaces

for (int space = 1; space <= spaces; space++)

System.out.print(" ");

spaces--;

// Printing symbols

for (int i = 1; i <= 2 * j - 1; i++)

System.out.print(symbol);

System.out.println( );

}

// Reseting number of spaces

spaces = 1;

// Lower half of the diamond

for (int j = 1; j <= columns - 1; j++) {

// Printing spaces

for (int space = 1; space <= spaces; space++)

System.out.print(" ");

spaces++;

// Printing symbols

for (int i = 1; i <= 2 * (columns - j) - 1; i++)

System.out.print(symbol);

System.out.println( );

}

}

}

Question:-

Write a program to display the following pattern.

Code:-

import java.util.*;

class Pattern

{

public static void main(String args[])

{

Scanner sc = new Scanner(System.in);

System.out.print("Enter the number of rows to print this pattern: ");

int n=sc.nextInt();

for(int i=1;i<=n;i++) // upper part.

{

for(int j=1;j<=n-i;j++)

System.out.print(" ");

for(int k=1;k<=2*i-1;k++)

System.out.print("*");

System.out.println();

}

for(int i=1;i<=n-1;i++) // lower part

{

for(int j=1;j<=i;j++)

System.out.print(" ");

for(int k=1;k<=2*(n-i)-1;k++)

System.out.print("*");

System.out.println();

}

}// end of main()

}// end of class.
