Boolean Cannot Be Dereferenced Java


All code has to live inside a method and all methods have to live inside a class. class has wrong version class file has wrong version 49.0, should be 48.0 You are compiling with theJava version 1.4 compiler, referencing class files compiled with the newer Java version 1.5 This sounds bizarre, but you were using an enum with some enum private methods. Cannot find symbol method XXX, where XXX is your class’s superclass constructor means you likely you did an explicit XXX() to call the superclass constructor first thing in your constructor instead http://kshelper.com/cannot-be/int-cannot-be-dereferenced-java-meaning.html

g. You may have used a reference to an inner class inside a static method. This approach makes code easier to maintain because it is easier to find the code that implements the class when it is fully qualified. Compareto Java missing } in a method static not valid on constructor static is not a valid constructor modifier You forgot your return type e.g.

Perhaps you wrote some initialisation code without enclosing it in static {} or plain {}. Int Cannot Be Dereferenced Java Meaning You are trying to write your generated class files to a directory where you don’t have permission, or the *.class files that you are overwriting may have been generated with a The enum constant is said to be created when the corresponding field is initialized. http://stackoverflow.com/questions/28213083/error-of-int-cannot-be-dereferenced Java cannot automatically convert a double to an int.

Returns:the reference id setProject public void setProject(Projectp) Set the associated project. You will have to globally rename enum to some other identifier, or convert the code to use the new built-in enum features.

Edit: For what it's worth, String.valueOf(int) is a bit faster than Integer.toString(int) on my system (Java 1.7). It can also mean you defined a method with the wrong visibility modifier, e.g. Bound mismatch Eclipse error: Bound mismatch: The generic method sort(List) of type Collections is not applicable for the arguments (ArrayList). this content not initialised Local variable x may not have been initialized.

Recompile with -Xlint:unchecked for details You used a Collection without generifying it. My implementation would look something like this: public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((dstAddr == null) ? 0 ArrayList) use java.util.List.length().
