Java text convertion

[J.Pluta]

James, I've done quite a bit of work with Java, including JDBC. Java data conversion normally works quite well. One caution in Java, though. Examine the following syntax: if (myString == "hello") This does not work. This only compares the addresses of myString and the literal constant that contains the word "hello". This was my most common mistake when I was learning Java. Instead, you must use the following: if (myString.equals("hello")) The second problem is that the conversion classes often return data with blank padding. If your field is ten characters long, you might need to compare as follows: if (myString.equals("hello*****")) (Replace the asterisks with blanks.) The other option, provided you are not worried about leading blanks, is to use the trim() method. trim() removes both leading and trailing blanks: if (myString.trim().equals("hello")) Again, be careful, because this will match any of the following fields: hello*****[*]hello****[*]*hello***[*]**hello**[*]***hello*[*]****hello (Again, where the asterisks represent blanks). If none of these work for you, please post your code and let us know what you're doing.

I'm having a problem converting text from the as400 to the java unicode format. What I'm doing is getting the data from physical file using as400 jdbc. I'm then comparing strings from the pc side to the data from the as400 but they will not equate e.g "hello" from the as400 is not = "hello" on the pc. Is this a text type conversion problem and if so how do I fix it?

Thanks, your solution works perfectly :-) Learning java from an RPG background has been interesting.
