Question

I am comparing strings from a text file, but for some reason they never match. If I do it in ruby it is very easy, but in processing I can not get it to work.
this is the ruby code that works:

f=File.open("priceMap_current_new.txt")

f.each do |str| 
    arrstr=str.split(";")
    if arrstr.length==1
        puts arrstr[0].inspect if arrstr[0]=="next\n"
    end
end

Now here’s the processing version that doesn’t work, actually it doesnt even work without reading from file:

String[] mystr={"number;zero","number;one","number;two","number;three","number;four"};

for(int i=0;i<mystr.length;i++){
  String[] numbers=split(mystr[i],";");
  if(numbers[0]=="number"){
    println("shoooooooooooooooooout");
  }
}

Additionally I would like to ask if there’s a way to inspect elements like in ruby, its very handy, because if I print pts[0] in processing I get “next” when its actually “next\n”
or also how to check datatypes in processing. Thanks!

Answer 1

Use if (numbers[0].equals("number"))

From: Processing doco

To compare the contents of two Strings, use the equals() method, as in
“if (a.equals(b))”, instead of “if (a == b)”.
