My code is running on my IDE (eclipse) and not on this website

Please check my code its working on my IDE

package lecture2; class ans1 { static void drawPattern(int N) { int n = N; int row = 1; int nst = 1; int nsp1 = n - 1; int nsp2 = -1; int val1 = row; int val2 = 1; while (row <= n) { int csp1 = 1; while (csp1 <= nsp1) { System.out.print(" "); csp1 = csp1 + 1; } int cst1 = 1; while (cst1 <= nst) { System.out.print(val1 + " “); val1 = val1 - 1; cst1 = cst1 + 1; } int csp2 = 1; while (csp2 <= nsp2) { System.out.print(” "); csp2 = csp2 + 1; } if (row != 1 && row != n) { int cst2 = 1; while (cst2 <= nst) { System.out.print(val2 + " "); val2 = val2 + 1; cst2 = cst2 + 1; } } System.out.println(); if (row <= n / 2) { nst = nst + 1; nsp1 = nsp1 - 2; nsp2 = nsp2 + 2; val1 = row + 1; val2 = 1; } else { nst = nst - 1; nsp1 = nsp1 + 2; nsp2 = nsp2 - 2; val1 = n - row; val2 = 1; } row = row + 1; } } public static void main(String args[]) { int N = 7; drawPattern(N); } }

@discobot Whenever you use Coding Blocks IDE your class name should be “Main” And there should be any package leture 2; in the code. Also you have to take input from the user don’t give hardcoded values to N instead use scanner to scan that value from user. So corrected Code is :


class Main {

	static void drawPattern(int N) {
		int n = N;
		int row = 1;

		int nst = 1;

		int nsp1 = n - 1;
		int nsp2 = -1;
		int val1 = row;
		int val2 = 1;

		while (row <= n) {

			int csp1 = 1;
			while (csp1 <= nsp1) {
				System.out.print(" ");
				csp1 = csp1 + 1;
			}

			int cst1 = 1;
			while (cst1 <= nst) {
				System.out.print(val1 + " ");
				val1 = val1 - 1;
				cst1 = cst1 + 1;
			}

			int csp2 = 1;
			while (csp2 <= nsp2) {
				System.out.print(" ");
				csp2 = csp2 + 1;
			}

			if (row != 1 && row != n) {
				int cst2 = 1;
				while (cst2 <= nst) {
					System.out.print(val2 + " ");
					val2 = val2 + 1;
					cst2 = cst2 + 1;
				}
			}
			System.out.println();

			if (row <= n / 2) {
				nst = nst + 1;
				nsp1 = nsp1 - 2;
				nsp2 = nsp2 + 2;
				val1 = row + 1;
				val2 = 1;
			} else {
				nst = nst - 1;
				nsp1 = nsp1 + 2;
				nsp2 = nsp2 - 2;
				val1 = n - row;
				val2 = 1;
			}
			row = row + 1;
		}
	}

	public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
		int N = sc.nextInt();

		drawPattern(N);
	}
}

Hi! To find out what I can do, say @discobot display help.

#5

sir i’ve updated my code. it isn’t working too

@discobot There are changes that has to be made in your logic
when you re printing spaces only then instead of single space print double space. (Not in System.out.print(val1+"") or val2 syso). Corrected Code is below :


import java.util.*;
class Main {

	static void drawPattern(int N) {
		int n = N;
		int row = 1;

		int nst = 1;

		int nsp1 = n - 1;
		int nsp2 = -1;
		int val1 = row;
		int val2 = 1;

		while (row <= n) {

			int csp1 = 1;
			while (csp1 <= nsp1) {
				System.out.print("  ");
				csp1 = csp1 + 1;
			}

			int cst1 = 1;
			while (cst1 <= nst) {
				System.out.print(val1 + " ");
				val1 = val1 - 1;
				cst1 = cst1 + 1;
			}

			int csp2 = 1;
			while (csp2 <= nsp2) {
				System.out.print("  ");
				csp2 = csp2 + 1;
			}

			if (row != 1 && row != n) {
				int cst2 = 1;
				while (cst2 <= nst) {
					System.out.print(val2 + " ");
					val2 = val2 + 1;
					cst2 = cst2 + 1;
				}
			}
			System.out.println();

			if (row <= n / 2) {
				nst = nst + 1;
				nsp1 = nsp1 - 2;
				nsp2 = nsp2 + 2;
				val1 = row + 1;
				val2 = 1;
			} else {
				nst = nst - 1;
				nsp1 = nsp1 + 2;
				nsp2 = nsp2 - 2;
				val1 = n - row;
				val2 = 1;
			}
			row = row + 1;
		}
	}

	public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
		int N = sc.nextInt();

		drawPattern(N);
	}
}
