Why this code gives no output

Question

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner (System.in);
int n = sc.nextInt();
for(int j=n;j<=1;--j){
for(int i=1;i<=j-1;++i){
System.out.print(" ");
}
for(int i=1;i<=1;++i){
System.out.print(j);
}
if(j<=n-1){
System.out.print(j);
}
}
}
}

Answer 1

Spaces are printed.
You didn't see them because you use println which outputs newline after printing spaces.
use print method instead:

for(int i=1;i<=n+1;++i){
System.out.print(" ");
}

Answer 2

The spaces are not printing of first if condition

Answer 6

import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner sc = new Scanner (System.in);
int n = sc.nextInt();

for(int j=n;j>=1;--j){
if(j==n){
for(int i=1;i<=n+1;++i){
System.out.println(" ");
}
System.out.print("0");
System.out.println();
}

for(int i=1;i<=j-1;++i){
System.out.print(" ");
}
for(int i=1;i<=1;++i){
System.out.print(j);
}
if(j<=n-1){
System.out.print(j);
}
if(j<=n-2){
System.out.print(j);
}
System.out.print("0");
System.out.println();
}
}
}
