Unfortunately, where the error points you to can be misleading. The “something” is sometimes just fine and the actual error is caused by the line before or after that piece of code. Anytime you forget or include an improper comma, semi-colon, quote, parentheses, bracket, etc., you’ll get this error. Here are some examples: Incorrect: int val = 5 Correct: int val = 5; Found one too many { characters without a } to match it Translation: You forgot to close a block of code, such as an if statement, a loop, a function, a class, etc. Incorrect: void setup() { for (i

PhiLho November 2014 edited October 2015 in Common Questions Why do I get a NullPointerException? One of the most common errors in Java (hence, in Processing) is this NullPointerException (short-named NPE). Fortunately, https://forum.processing.org/two/discussion/8071/why-do-i-get-a-nullpointerexception it is also one of the easiest to fix, once the most common cases are known. Null? Pointer? Exception? First, what is this name? It is one of the most misnamed class of Java, because this language has no pointers! This has probably historical roots, when people wrote the Java compiler in C or C++, where the word 'pointer' comes from. Java has no pointers but references, which fill the same role, in a safer way (no risk of memory corruption!). An Exception is a language mechanism allowing to handle exceptional cases, usually errors. Your program, or some class, throws an exception when an unrecoverable error happens (programming mistake, file isn't there, program can't connect to network, etc.) and should be handled at a higher level (by the programmer). Some of these errors come from a programming error, so you just fix the error to get rid of it (we will see that for NPE here), others, like not being able to open a file, must be handled by a try / catch construct, but that's outside of the scope of this article. And what is Null, or, rather, null? It is a special Java value, indicating that an object refe

I'm working on a scientific project in biologies (the idea is a virtual reality for stationary flying insects) and I use Processing for visualizing an analog input signal sent from an Arduino microcontroller. Yesterday everything worked fine processing error but today appeared an error and Processing crashes while startup. Can someone please help me to solve the problem? I allready updated Java and installed Processing again, but I couldn't find a solution. I'm working on Windows 7 32bit, Processing 2.0.3. Best, Soren 1 Replies(4) PhiLho Re: Startup Error java.lang.NullPointerException 23 days ago Have you installed processing error nullpointerexception a new Mode? Perhaps you can try and uninstall it. Some people also had Processing working again after deleting its preferences. Leave a comment on PhiLho's reply soeren02 Re: Startup Error java.lang.NullPointerException 23 days ago Hey, thanks for your reply. I didn't install a new Mode, I just executed some codes. I also deleted the preference.txt, now the starting window pops up but closes after a few seconds and nothing happens. The error isn't shown any longer, but Processing isn't starting correctly. Now I created a launch4j.log file which describes what's happening during the startup, Il will post it also. Does it display something unregular?

But when i begin rewriting the code into a setup and draw setup(i think its called active), it gives me a "NullPointerException", when running it. Can it be something with the arrays? hope you can help me :) (and yes i know it is alot of slave code writing, but it was the only way i could figure it out :3 im a newbie to processing and coding in general. also i ruled out some of the slave stuff, so it was only the code i know gave me problems): //stating the int's and strings String[] lines = loadStrings("brown.txt");//the array with the words String longString = join(lines, " "); //joining the array to a normal string of words int characters = longString.length(); //used to find the amount of all the letters String lowercase = longString.toLowerCase();//makes sure all the letters are lowercased //setting up the letter freqiency finder char[] c = lowercase.toCharArray(); //used to make a character array int freq = 0, freq2 = 0, freq3 = 0, freq4 = 0, //| freq5 = 0, freq6 = 0, freq7 = 0, freq8 = 0, freq9 = 0, //| freq10 = 0, freq11 = 0, freq12 = 0, freq13 = 0, //|naming and setting all the frequencies freq14 = 0, freq15 = 0, freq16 = 0, freq17 = 0, freq18 = 0, //| freq19 = 0, freq20 = 0, freq21 = 0, freq22 = 0, freq23 = 0, //| freq24 = 0, freq25 = 0, freq26 = 0; //| void setup() { size(600, 600); background(255); } void draw() { //setting up the letter counters for (int i = 0; i< c.leng
