- State the purpose of using “static” keyword in java with example.19- java. Which of the following is a drawback of using recursion? It may be less efficient than an iterative version. It may have fewer lines of code than an iterative version. It uses lesser memory stack than an iterative version. It runs faster than an iterative version.Q1. Write a java program using recursion to find the power of a number x", where x is double and n is integer. (Hint: x"-1). Q2. Write a Java program to demonstrate autoboxing and unboxing of byte and short. (Hint:The conversion of primitive data type (for example, int) into its corresponding wrapper class(for example,Integer) is known as autoboxing and the reverse process is known as unboxing.) Q3. Write a java program to accept three strings, slas “java Programming" and s2 as "ADVANCE JAVA" s3 as "Programming concepts in Java" Find length of s3. Change sl to Upper case and s2 to Lower case. Q4. Write the class definition and draw the class diagram for the following: Class Name Bank Attributes: private: Bname, code public: Phone, city Methods public: manage, deposit, withdraw Q5. a) Write a java program to demonstrate the use of mutable objects to find the Perimeter of a rectangle using Point (10,4) .Perimeter = 2(length + breadth). b) What is the purpose of a garbage collector?
- Implement in C Programming 6.10.1: Function pass by pointer: Transforming coordinates. Define a function CoordTransform() that transforms its first two input parameters xVal and yVal into two output parameters xValNew and yValNew. The function returns void. The transformation is new = (old + 1) * 2. Ex: If xVal = 3 and yVal = 4, then xValNew is 8 and yValNew is 10. #include <stdio.h> /* Your solution goes here */ int main(void) { int xValNew; int yValNew; int xValUser; int yValUser; scanf("%d", &xValUser); scanf("%d", &yValUser); CoordTransform(xValUser, yValUser, &xValNew, &yValNew); printf("(%d, %d) becomes (%d, %d)\n", xValUser, yValUser, xValNew, yValNew); return 0;}Please use Python for this question: Inheritance (based on 8.38) You MUST use inheritance for this problem. A stack is a sequence container type that, like a queue, supports very restrictive access methods: all insertions and removals are from one end of the stack, typically referred to as the top of the stack. A stack is often referred to as a last-in first-out (LIFO) container because the last item inserted is the first removed. Implement a Stack class using Note that this means you may be able to inherit some of the methods below. Which ones? (Try not writing those and see if it works!) Constructor/_init__ - Can construct either an empty stack, or initialized with a list of items, the first item is at the bottom, the last is at the top. push() – take an item as input and push it on the top of the stack pop() – remove and return the item at the top of the stack isEmpty() – returns True if the stack is empty, False otherwise [] – return the item at a given location, [0] is at…Implement in C Programming 6.25.1: LAB: Fibonacci sequence The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which has an index n as a parameter and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: Fibonacci(7) is 13 Note: Use a for loop and DO NOT use recursion. #include <stdio.h> int Fibonacci(int n) { /* Type your code here. */} int main(void) { int startNum; scanf("%d", &startNum); printf("Fibonacci(%d) is %d", startNum, Fibonacci(startNum)); return 0;}
- Java Programming- Need the code- Suppose we have a string holding the text of an entire book. If we want to analyze segments of the text, it is inefficient to make substrings. Instead, we should just store a reference to the original text and the starting and ending positions. Design a class Segment that does this, and have it implement the CharSequence interface of the standard library. Write a test program in which you demonstrate that you can pass your Segment objects to methods that accept CharSequence instances, such as String.join and PrintStream.append.Answer the given question with a proper explanation and step-by-step solution.

If this sum is less than N, the number is said to be deficient. If the sum is greater than N, the number is said to be abundant.The first few perfect numbers are 6, 28, 496, and 8128.
