[Java] Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 10 - ls Pls help me to solve

Hi,
I've started learning Java and creating small programs and compiling on my own using EditPlus Editor and Command Prompt.
No doubt, my prorgram will tell you I'm a beginner.

javac Temperature.java was successful.

When I fire java Temperature I got the follwoing error.
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 10
        at Temperature.main(Temperature.java:44)

I can see my "if clause" compares the values in the first row from the Print staements. After that it's throwing error. Somebody please help me to find out and fix this error.

Thanks in advance
Sri
