java intro Please explain this to me, why return value is like this. There are only two methods calss, why there are 3 rows in table. How can we get the answer false true false. I am struglling with reference and trace memory. Please be specific.

write a code in java (using recursion)

writing a general-purpose sort method in Java, the sort method needs to compareobjects. There are two ways to give the sort method the code to compare objects,implementing the interfaces Comparable and Comparator respectively. Briefly, describe thetwo ways. Write excerpts of use examples

Java source code writing - a recursive algorithm. Please use non-recursive and recursive ways to compute the nth Harmonic number, defined as H. Turn in your java source code file with three methods, including one main() method.

No handwritten answers please, computerized only please please do not code this in java, only help me do a diagram insertion sort: 21, 4, 25, 16, 12

In java if i have this pseudo code that tries to explain how a method will work using recursion how can i turn this into working java code

When an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index. In this project, you…

Please help me with this using java and recursion. Please also comment the code. Please do not use hashtags when creating theses fractals. And provide an image of the output.  (Just pick one) 1) create a sierpenski triangle fract   2) create a viscek fractals

Can u answer this please

Using recursion and java, please make a sierpenski carpet Please also comment the code just like the image below. Do not make it fill of hastags
