   • Dictionary of ArrayLists in Java

     Top Answer

     Answered Jun 05, 2012 · 2 votes

     Instead of ArrayList grades; you'd have to use ArrayList grades = new ArrayList();

     Yet better: ArrayList<Float> grades = new ArrayList<Float>(); //or use Double or Number

     Note that unlike C or C++ creating a variable doesn't create the object as well. In C++ you could imagine your code as ArrayList* grades; i.e. you'd just create the reference/pointer here.

     Additional thoughts:

     • Dictionary studentGrades; this will be initialized to null.
     • public void main(String[] args) that's not a valid main function since it would have to be static
     • if you have a public static void main(String[] args) you can't use this since you don't have an object instance in the static context
     • You can't instantiate Dictionary since it is abstract. Use one of its subclasses, e.g. new Hashtable<String, List<Float>>(), or a map, e.g. Map<String, List<Float> dictionary = new HashMap<String, List<Float>>();
     • Note that local primitive variables are also not initialized, so this could give you an error too: boolean res; In Java only class members are initialized, local variables are not.

   • Dictionary sorting of ArrayList of Arraylist in java

     Top Answer

     Answered Mar 23, 2019 · 2 votes

     Comparator functions that contain 1 or -1 are error prone.

     Instead, you should write it like this:

     public static int lexicographically(List<Integer> a, List<Integer> b) { for (int i = 0, end = Math.min(a.size(), b.size()); i < end; i++) { int res = Integer.compare(a.get(i), b.get(i)); if (res != 0) return res; } return Integer.compare(a.size(), b.size());}

     This style of writing comparator functions prevents various common mistakes, such as never returning 0.

     The most important pattern in this style is:

     • Compare by the first criterion.
     • If the given values differ, return the comparison result and be done.
     • Take the next criterion, continue with step 1.
     • If there are no criteria left, return 0.

   • Eight queens in Java in recursion

     Top Answer

     Answered Nov 25, 2012 · 0 votes

     In Java, when you pass the object to the method, you copy the reference to the object. So, changes made to the object are visible by all references to that object (including the one you keep in the calling method).

     There are two solutions for it:

     • Copy the HashSet before doing modifications, and do the modifications to the copy. In case a solution is found, return the new copy. In case it does not work, return the original copy.
     • Use a data structure thtat depends in an index, so you can ignore all values that should not still be set. For example an array, if you are iterating for the 5th queen you can ignore the values of the fifth, sixth, seventh and eighth queens if they are set.

     I find more clear the queens problem implemented with an int array, but that is left to everybodys taste.

   • Function of jxl.jar in java

     Top Answer

     Answered May 09, 2011 · 1 votes

     jxl.jar is the library of JExcelApi , which is a open source java API to read, write, and modify Excel spreadsheets dynamically. It contains all the compiled *.class files, associated metadata and resources that are used by the Java Excel API internally .

     Java library are distributed as a .jar file .You can refer to this for more info about JAR.

     As the official API of JExcelApi does not contain a file called jxl.java .I believe this is the Java class created by you to test the function of JExcelApi . To use the JExcelApi , you have to import the necessary classes from the jxl.jar and specified jxl.jar to be on the class path when you compile jxl.java .

     So , the connection between jxl.java and jxl.jar is that jxl.java calls the classes from jxl.jar to manipulate the Excel.

   • version of java SDK in javaFX SDK

     Top Answer

     Answered Nov 20, 2010 · 1 votes

     I do not believe that the JavaFX SDK includes the standard JDK. If you have NetBeans installed, you probably have the standard JDK installed, as it is listed in the software requirements for NetBeans (here). I don't know why some classes would be missing, but the entire JDK should be available. Someone please correct me if I am wrong.

   The Dictionary class is the abstract parent of any class, such as Hashtable, which maps keys to values. Every key and every value is an object. In any one Dictionary object, every key is associated with at most one value. Given a Dictionary and a key, the associated element can be looked up. Any non- null object can be used as a key and as a value.

   Why is Java 8 so popular?

   • Java 8 adds a lot of new classes and extends existing ones in order to provide better support of modern concurrency, functional programming, date/time, and many more. The famous NullPointerException is by far the most popular cause of Java application failures.

   What is a functional interface in Java?

   • As a result, the concept of functional interfaces has emerged. The function interface is an interface with just one single method. As such, it may be implicitly converted to a lambda expression. The java.lang.Runnable and java.util.concurrent.Callable are two great examples of functional interfaces.
