John here Need correct Java code for the following with output "Welcome" returns 2
**** JAVA ****
Part (1) Write a recursion method named CalculateSeries, that will receive one integer valuen as parameter. The method will calculate and return the term n in the following series: T(0)= 0 T(n)= 2 T(n-1) +1 Part (2) Write the main method to test your method. Enter n >> 5 T(5) = 31 %3D
The following recursive method get Number Equal searches the array x of 'n integers for occurrences of the integer val. It returns the number of integers in x that are equal to val. For example, if x contains the 9 integers 1, 2, 4, 4, 5, 6, 7, 8, and 9, then getNumberEqual(x, 9, 4) returns the value 2 because 4 occurs twice in x. public static int getNumberEqual(int x[], int n, int val) { if (n< 0) ( return 0; } else { if (x[n-1) == val) { return getNumberEqual(x, n-1, val) +1; } else { return getNumber Equal(x, n-1, val); } // end if ) // end if } // end get Number Equal Demonstrate that this method is recursive by listing the criteria of a recursive solution and stating how the method meets each criterion.
Given a long string use recursion to traverse the string and replace every vowel (A,E,I,O,U) with an @ sign. You cannot change the method header. public String encodeVowels(String s){ // Your code here }
Write a program called Recursive_fibonacci.java that implements a recursive function for computing the nth term of a Fibonacci Sequence. In the main method of your program accept the value of n from the user as a command-line argument and then call your function named Fibonacci with this value. The output should look exactly like what is pictured below.
Please help me with the below using java. Please also comment the code (explai. What each li e is doing). Please make sure both codes are completed using recursion
Please explain the questions related to the code below: //1. Why is 20 printed 3 times and why does it start with 1, but end with 2? //2. What is the base case for this recursive method and why? //3. How would you implement this using a loop? //4. What is each if statement checking? //5. Would a solution to this using loops require more or less code and would it be more or less effecient? //6. Why is recursion a good choice to solve this problem? //7. How can recursion become infinite? //8.

Write a recursive method to determine whether a String contains a 'q' not immediately followed by a 'u' (ignoring capitalization). In other words: • the word does contain at least one 'q' • and that q is followed by anything except a 'u' Carefully review the provided driver program to see example test cases. The method header is: public static boolean qNotFollowedByU(String word)
Using Java: Write a recursive method called 'vowels', that returns the number of vowels in a string
