hi Raghav.. in video at 10:58 you said it will print from 1 to 4 index digits/chars but i can see the output is coming b/w 1 to 4. mean 3 digits (if its 1 to 4 then it will have 4 digits)

[@RaghavPal]

Hi In Groovy, the .subSequence(int start, int end) function is used to extract a portion of a string, starting from the start index (inclusive) and ending at the end index (exclusive) str.subSequence(1, 4) extracts the substring starting at index 1 and ending at index 4 (not including the character at index 4) Sorry if it was a mistake in the video

@@RaghavPal No Problem, Really Helpful...Thanks a lot for your explanation Bro.👍

[@MaheshJoshi_wellington]

This is amazing ! Will help me in katalon ! Raghav how I can get the 10% from following line using groovy string here is string "Cancel >14 days before Start Date 10% Unit Price: $16.00 , Qty: 1 , Total: $16.00" In above things are - 10% will always have 1 space before 10 and 1st sentance will always end with percentage I mean 10% or 20 or 30 etc..

[@RaghavPal]

Hi Mahesh, you can use regular expression to get the text out of the string. Groovy uses symbol =~ to check match with the help of regular expression. Like in your case you can use regular expression /(?:10\%)/ and then write a groovy code as follows: String regex = /(?:10\%)/ def match = str1 =~ regex if (match) { println "Success" println match[0] }

@@RaghavPal I am new to programming I will practice thanks a lot downloading eclipse now will go through your series.wht is best Intelleg IDE OR eclips ?

[@RaghavPal]

Glad to know Mahesh, Eclipse or INtelliJ, both are good, I cannot do a un-biased suggestion as I have been using Eclipse since the beginning, However, if you choose to go with IntelliJ, that should also be fine.

When it comes to concatenation when would you want to use "+" over the ".concat" method?

[@RaghavPal]

Hi Brian, interesting question, This will help you to get details This will hold true for both java and groovy www.geeksforgeeks.org/difference-between-concat-and-operator-in-java/ stackoverflow.com/questions/693597/is-there-a-difference-between-string-concat-and-the-operator-in-java

Can we write like str1==str2 for string comparison in groovy? or will it compare their locations and not actual content?

[@RaghavPal]

Hi Kshipra, can use this

[@TheSwatisadhukhan]

what is the difference between slashy and dollar slashy? When both are giving the same output.

[@RaghavPal]

Hi Swati, if you're defining a regular expression pattern, then slashy strings are useful as you don't need to escape backslashes, ie /\s+/ However, if you need a forward slash in your pattern, you'd need a dollar slashy string $/([a-z]+)/([a-z]+)/$ stackoverflow.com/questions/31911446/whats-the-purpose-of-dollar-slashy-string-in-groovy
