java.lang.NumberFormatException: For input string: “null”

Question

I\'m parsing a doc and I get the following error:

Exception in thread \"main\" java.lang.NumberFormatException: For input string: \"null\"
    at sun.misc.Fl

Based on your error, it is very possible your latValues[i].trim() displays the value "null". I'm able to replicate your problem here:-

Float.valueOf("null");

Here's the stacktrace:-

java.lang.NumberFormatException: For input string: "null"
    at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1301)
    at java.lang.Float.valueOf(Float.java:375)

In another word, the value you have is not null, but it contains the word "null".

If you do Float.valueOf(null);, that actually gives you a NullPointerException, which is not what you have here.
