Please refer to below code to print triangle in java. Try to execute it in eclipse(Force.com IDE)
import java.util.Scanner; class RevTriangle{ public static void main(String agrs[]){ Scanner k = new Scanner (System.in); int line = k.nextInt(); int x = (line * 2) - 1; int y = 1 ;
for(int l = 0; l < line; l++){
for(int s = y; s > 0; s--){ System.out.print(" "); }
for(int s = 0; s < x ; s++){ System.out.print("*"); }
