[Solved] How to make two dimensional LinkedList in java?

by

[ad_1] from your question, I think (not 100% sure) you are looking for java.util.LinkedHashMap<K, V> in your case, it would be LinkedHashMap<String, Double> from java doc: Hash table and linked list implementation of the Map interface, with predictable iteration order. This implementation differs from HashMap in that it maintains a doubly-linked list running through all … Read more

[Solved] How to design mathematical program which calculate the derivative of a function using python? [closed]

by

[ad_1] Taking a function is easy… it’s just like any other argument. def example(somefunc): somefunc() example(someFunction) example(lambda x: x ** 2) Returning one is a little trickier, but not much. You can return a lambda: def example2(): return lambda x: x + 1 Or you can build an inner function, and return that def example3(): … Read more

[Solved] substring methods java

by

[ad_1] String.substring() is a method, not a field, meaning you need to call str.substring() rather than simply str.substring. Further, the substring method takes parameters – you have to tell it the specific substring you want in the form of which indexes within the string. str.substring(0, 2) would print characters 0 and 1 (the upper bound … Read more

[Solved] why some imports cannot be resolved?

by

[ad_1] This is because your compiler is not able to find the necessary packages and or libraries that are needed to resolve these imports. These packages must be included in your class path. For example all of the errors regarding org.apache.felix.scr.annotations.x can be resolved after downloading the latest .jar from https://mvnrepository.com/artifact/org.apache.felix/org.apache.felix.scr.annotations/1.11.0 Follow these steps to … Read more

[Solved] java – string return method is called before any value is assigned to string

by

[ad_1] It seems pretty logical to me: You have a first event handling method execution in the EDT which gets the firmware version and then gets the port reader. Getting the firmware version causes an event to be received, in a different thread (and thus in parallel to the execution of portsMethod() in the EDT). … Read more

[Solved] Boxing and Performance [closed]

by

[ad_1] Boxing is considered slow because it implies the allocation of an object. In your case that object is short lived (will probably not survive Gen0), which makes it cheap. A recent microbenchmark I did put the cost of generating a short lived object at about ~15 CPU cycles. Cost might be a bit higher … Read more

[Solved] What’s the difference in these three variable definition?

by

[ad_1] Of your three examples, _foo1 and _foo3 are both instance variables (ivars) and are functionally equivalent (though there are some old compilers that that didn’t permit ivars in the @implementation). I’ve seen people argue passionately for the @implementation pattern, your _foo3 example. See the somewhat dated Where to put iVars in “modern” Objective-C? But … Read more
