- plz help with the following: IN JAVA Why does the following method have a compile errorConsider the method headings: void funcOne(int [ ] alpha, int size) int funcSum(int x, int y) void funcTwo(int [ ] alpha, int [ ] beta) and the declarations: int [ ] list = new int [50]; int [ ] Alist = new int [60]; int num; Write Java statements that do the following: a. Call the method funcOne with the actual parameters, the array list and 50, respectively. b. Print the value returned by the method funcSum with the actual parameters, the thirtieth and tenth components of list, respectively. c. Call the method funcTwo with the actual parameters, the array list and array Alist, respectively.Write a complete Java program that allows users to enter two integer numbers as follows: pleaes Enter the first number: 2 please Enter the Second number: 2 Upon providing the two integer numbers, the users should be given a list of operations to select from, as follows: please choose the operation you want to do with these numbers by Enter a,b or c: a- adding b- multiplying c- average Based on the users’ selection, a method should be called to perform the selected operation and return the result. After that the main method should print the result. The output of the program should be as follows in the picture:
- 3. Write a Java program to implement a method which prints the Fibonacci series up to nth term. The value of n will be taken from the user in the main() method.Fibonacci series starts with 0 and 1, and the sum of previous two numbers is the next number of the series. For instance, 0, 1, 1 (0 + 1), 2 (1 + 1), 3 (1 + 2), and so on.Sample output [assuming the number of term (n) is 8]:The Fibonacci series: 0 1 1 2 3 5 8 13WRITE A JAVA PROGRAM Methods can be used to define reusable code and organize and simplify code. Problem:- Suppose that you need to find the sum of integers from 5 to 15, from 16 to 30, and from 31 to 39, respectively. Define a public static sum method that take two int parameters -> (int start, int end) In the method, use for loop to add all the number from start to end. Later, invoke the sum inside the main method. Do the sum for each a) 5 to 15; b) 16 to 30; and c) 31 to 39 separately and later print the results. Output: Sum from 5 to 15 is 110 Sum from 16 to 30 is 345 Sum from 31 to 39 is 315Please give a full detailed optimized solution in Java 8 for the given problem, use the example code provided as well. Please provide comments and screenshots of code and output. Also, add the time/space complexity and the reason for it.Java 8 Code Example:import java.io.*; import java.util.*; import java.text.*; import java.math.*; import java.util.regex.*; public class Solution { public static void main(String args[] ) throws Exception { /* Enter your code here. Read input from STDIN. Print output to STDOUT */ } }
- Write a Java program Primes that finds all possible prime numbers in the range of (1, n], where 1 < n ≤ 1000. Solve the problem by implementing and using the helper method isPrime(number) which determines whether the given argument is prime or not. Example: Input 5 Output 2 3 5 (Consider the structure of the code that is given in the picture. The structure must be the same)Overriding static and private methods is allowed in Java. Consider the following statement.Write a recursive Java method that calculates the sum of n positive integer numbers. The math function is: f(n) = 1 + 2 + 3 + … + n. Jack, Peter and John were exploring a tunnel which allows only one person to pass through. Jack entered the tunnel first, followed by Peter. John entered the tunnel the last. The tunnel has a dead end. So the team has to turn back and retrieve from the tunnel one by one. Write a Java program based on a suitable data structure to simulate this process.
- Consider the following C function or Java method (except for final printstatement the code is the same):void fun (int x) {int a, b, c, d;d = 1;for (a = 1 ; a <= x ; a ++) {b = a;c = 1;while (b > 0) {c &= b % 2;b /= 2;}d += c;}printf ("%d\n", d);}void fun (int x) {int a, b, c, d;d = 1;for (a = 1 ; a <= x ; a ++) {b = a;c = 1;while (b > 0) {c &= b % 2;b /= 2;}d += c;}System.out.println (d);} (a) What output will be printed for input value x = 8 ?(b) How many dierent input values x cause the function to print theresult 8 ?(c) Write a function with the same behavior but only one loop (of anytype) and no library call except for the print statement.Write the Java program: Make sure to have proper code indentation.
