In the previous solution, the LESS THAN and GREATER THAN symbols have nit been parsed.
public class Check {
	public static void main(String[] args) {	
		int limit = 9;
		int i=0,j=0;
		for(i=0;i  limit-i;j--)System.out.print(" ");
			for(j=limit;j > i;j--)System.out.print("* ");
			System.out.println();
		}
		j=limit;
		for(;limit > 1;limit--){
			for(i=2;i  limit-2;i--)System.out.print("* ");
			System.out.println();
		}
	}
