//Indian rupee Rs.1... was causing problem because my code was writing in hindi characters // at first. And second, third, etc. times as well //The next problem, when I thought I found the solution: //Error: I used a non-ASCII character ("₹") - Headshot, thanks Java8 //Finally there is a working solution (I got help from a smarter one, thx for him). I didn't know it "currInr.startsWith" //I hope I could help if someone would have need it
