Populating HashMap - Code Too Large Compilation Error

Mar 17, 2014

We are getting "Code too large" compilation error for one of our class. This class contains public String fields for label ID and value. We use this class for localization, except for English all other language labels come from .properties files.
 
The reason we are getting this error is because we have a static block in which using reflection we are populating a HashMap with all public fields and their value. The number of fields have gone up to the extinct where we are crossing the 64K limit for a static method. One of the most feasible solution was to use .properties files for English labels as well.
 
I will be calling this class MyLabels. We defined a super class for MyLabels called MyLabelsExt. And now we are adding labels into the super class instead of the MyLabels. By running some tests we confirmed that the map that we initialize in MyLables class contains all the fields from both MyLabels and MyLabelsExt class.
 
How is the 64K limit error not coming if the labels are defined in a super class. Does that mean Java is able to identify that some of the fields are coming from parent class, and that is being treated as separate from the child class. And how is the map that we initialize having all the value.

No Compilation Error - No Class File Produced

Dec 24, 2014

I've a .java file that won't compile, but produces no errors (in cmd prompt).

I think its the import of java.util.ArrayList thats causing the problem (because it can compile a different file in the same source folder) - so i'm assuming its the classpath that is wrong. which is fine. i love fighting with classpaths.

But why isn't it providing me with an error. the compiler usually goes bat-sh.. crazy if the -cp is incorrect!

Its because I'm switching between command prompt and a text editor and it hadn't saved the file for some reason, and still won't am getting rid of this editor!!

How To Make Difference Between Compilation Fails And Runtime Error

May 5, 2014

I want to know if there is any general rule/pattern about things which give compilation fails and things which go for Runtime error/exception. OR only way is to remember all of them and there is no actual pattern in it.

I'm having some difficulty getting this GUI dice game to compile. I'm using javac and notepad++ for this and I'm getting the following errors:

BlueJ Error Code

Apr 6, 2014

the system I am using is blue jay and java. my problem is that I have this error message pop up whenever I try to compile any of my 6 classes. Three of the classes are cities, 3 others are shops, and the final one is a inventory called Player. The following is the error code that appears when I try to compile class THshopB or class CityB.

method run in class CityB cannot be applied to given types;required: Player; found: no arguments; reason: actual and formal argument lists differ in length

A similar error occurs for the rest of my City and THshop classes,except it replaces the class CityB with CityA and occurs in class THshopA, replaces CityB with CityC when occurring in class THshopC.The public methods of CityB and THshopB are shown below, as I believe that something is wrong with the public method of one or the other. I have the code [CItyB.run();}] inside of class THshopB, and run is the part that gets the red highlight error described above.THshopB public method

[ public static void shop(Player inventory){
CityB.run();}]
CityB public method
[ public static void run(Player inventory){
THshopB.shop(inventory);]

All of my THshop classes are written in the same format, and all of my City classes are written in the same format,

There are 2 methods and a main one. The first is a void that creates a 3x4 2d array and the second is to search for a value in the array, if found it will return the number of the row that contains that value. If not, it will return -1, but I am getting 1 error and 1 dead code warning.I will put comments at the lines that contain the problems

import java.util.Scanner;

Variables Over Methods - Unresolved Compilation

Mar 17, 2015

I'm making a java program that can "convert" java to arduino by sending commands over a serial port. I'm using the JSSC library, and using methods to shorten things up a bit.

I've already made the code that starts up the serial port and it does connect. But I've made two different classes for the methods. One for the RXTX and one for the Arduino.

I'm making it so that I can just type:

Java Code:

public static void main(String[] args) {
RXTX.SerialSetup();
Arduino.pinMode(2, 0);
} mh_sh_highlight_all('java');

And it will start the serial port and set pinmode on pin 2 to output.

But when I try it I get this error:

Java Code:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

serialPort cannot be resolved mh_sh_highlight_all('java');

I don't know if its possible to 'send' a variable to a different method.
