Sign In·ViewThread·Permalink What happens here? When a library declares a compile-time dependency on a SLF4J binding, it imposes that binding on the end-user, thus negating SLF4J's purpose. Can 'it' be used to refer to a person? Could not understand what you mean by "than to create dynamically "?? –Manish Basantani Dec 10 '10 at 6:15 1 When you pass a struct variable to or return it http://stackoverflow.com/questions/4406178/cannot-have-instance-field-initializers-in-structs-problem

Error Cannot Have Instance Field Initialized In Struts

Should I serve jury duty when I have no respect for the judge? Isn't that the whole point of having structs and classes - to have value and reference semantics? protected java.lang.String internalName The Java base name of our internal resources. But the layout of reference objects is manifested in the same way even in C#.

If you pass a value type to a method, the default (without an out or ref keyword) is to pass "by value"; a shallow copy of the instance is created for If possible, making the inner class a static inner class (also known as a nested class) should solve the problem. I've never used Java but I am curious. That means that values can be passed with only the overhead of a single pointer just like in C++.

As most comparators have little or no state, making them serializable is generally easy and good defensive programming. And if you do want to treat an int as an object, C# allows that too. Use this substring to map to the Java class name of the corresponding action class (an implementation of the Action interface). SLF4J versions 1.4.0 and later requires log4j 1.2.12 or later The trace level was added to log4j in version 1.2.12 released on August 29, 2005.

Although this will probably satisfy the contract that equal objects must have equal hashcodes, it is probably not what was intended by overriding the hashCode() method. (Overriding hashCode() implies that the To avoid such problems, the C# compiler disallows definition of a default constructor by the user. share|improve this answer edited Dec 20 '12 at 22:17 answered Jul 12 '11 at 17:16 KeithS 15.3k33361 Good answer! To correctly override the compareTo() method in the Comparable interface, the parameter of compareTo() must have type java.lang.Object.

Consider throwing a RuntimeException instead. Thus, when you include cassandra-all as a dependency in your project, the cassandra-all declaration will cause both slf4j-log4j12.jar and log4j.jar to be pulled in as dependencies. Use whole words-avoid acronyms and abbreviations (unless the abbreviation is much more widely used than the long form, such as URL or HTML). In C#, struct carries only value semantic, and class — only reference semantic. C# Initialize Struct

A method of the class would work as a callback for the structure's instance.

Placing one (and only one) of slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar on the class path should solve the problem.

You don't want to derive from other types or let others derive from your type. FindBugs attempts to detect and suppress such cases, but may miss some. In your project's pom.xml file, exclude this SLF4J binding when declaring the unscrupulous dependency. public class CircularClassInitialization { static class InnerClassSingleton extends CircularClassInitialization { static InnerClassSingleton singleton = new InnerClassSingleton(); } static CircularClassInitialization foo = InnerClassSingleton.singleton; } IMSE: Dubious catching of IllegalMonitorStateException (IMSE_DONT_CATCH_IMSE) IllegalMonitorStateException is

IC: Superclass uses subclass during initialization (IC_SUPERCLASS_USES_SUBCLASS_DURING_INITIALIZATION) During the initialization of a class, the class makes an active use of a subclass. You want others to operate on a copy of your data (basically pass by value semantics). At one point, something must be pushed on the stack and popped on the other side, so then that *something* will be passed by value. This may result in a file descriptor leak.

When a struct gets bigger, it gets slower because a lot more data must be copied whenever it is passed anywhere. –Excrubulent Nov 25 '13 at 19:43 add a comment| up Subclasses may override this method to reset bean properties to default values, or the initialize() method may be used to initialize property values to those provided in the form property configuration Where is the confusion here?
