Nested Loops Triangle Pattern Help

[Xeel]

a quicker version:

public static void main(String[] args) {
    
    int top = 13;
    int s = 0;
    
    for (int i=0; i<top*2+1; i++){
        s = Math.abs(top-i);
        if(s!=0){
            for(int j=top; j>s; j--){
                System.out.print(" ");
            }
            for (int j=0; j<s; j++){
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}
