This code is a conditional comparison check, and the logic proceeds as follows:

1. Retrieve and Trim transArsInfo Description:

   • transArsInfo.getDescription().trim() fetches the description from transArsInfo, and trim() removes any leading or trailing whitespace for comparison purposes.

2. Construct & Trim the bankTransaction Description:

   • (bankTransaction.getDescription() != null ? bankTransaction.getDescription() + ", " : StringUtils.EMPTY) adds bankTransaction's description (if not null) followed by a comma ", ". If bankTransaction.getDescription() is null, it uses StringUtils.EMPTY (an empty string).

   • (bankTransaction.getMerchantName() != null ? bankTransaction.getMerchantName() : StringUtils.EMPTY) appends the bankTransaction's merchant name if it's not null. If bankTransaction.getMerchantName() is null, it uses StringUtils.EMPTY.

   • The two pieces of information above (description and merchant name) are concatenated to form one combined string:

     (Description + ", " + MerchantName)
     

   • The combined string is then trimmed using .trim() to remove any leading or trailing whitespace.

3. Comparison:

   • The trimmed transArsInfo description is compared using .equals() to the trimmed concatenated string composed of the bankTransaction.getDescription() and bankTransaction.getMerchantName(). This checks if the two strings are exactly the same.

What the Code Does:

The code checks if the trimmed description from transArsInfo matches the trimmed concatenated value of bankTransaction.getDescription() (appended with a comma, if not null) and bankTransaction.getMerchantName(). If the two strings are identical, the equals() method will return true; otherwise, it will return false.
