Explain public static void main(String args[])

Q2: Order of operations and math data types  Use the Java IDE to create and run the following program: // Java program by [Student name] [Today's date] public class MathExample {        public static void main(String[] args) {               System.out.println(3/2+3);               System.out.println(0.5*3+4/2);               System.out.println(0.5*2/3+10/2);        } }              Please answer the following questions.  What type of literal is 3: double or Integer? What type of literal is 0.5: double or integer? For the first expression, why is first value printed 4 instead of 4.5? For the second expression, which math operation is done last? Use parentheses to change the third expression so (3+10) is calculated first. Paste the revised expression here: Please give a full explanation of the program. Please keep in mind that I am a beginner and please keep it simple.

Write a recursive method in java that sums all values between s and n inclusive     /*   assume s is less than or equal to n to start */    public static int sum(int s, int n)    {           }

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.

Write a recursive methor called, doMyMath, which takes as input any positive integer and calculates the factorial.Javascript

JAVA Language:  Transpose Rotate.  Question:  Modify Transpose.encode() so that it uses a rotation instead of a reversal. That is, a word like “hello” should be encoded as “ohell” with a rotation of one character. (Hint: use a loop to append the letters into a new string)         import java.util.*;            public class TestTranspose {        public static void main(String[] args) {          String plain = "this is the secret message";   // Here's the message           Transpose transpose = new Transpose();          String secret = transpose.encrypt(plain);          System.out.println("\n ********* Transpose Cipher Encryption *********");          System.out.println("PlainText: " + plain);    // Display the results          System.out.println("Encrypted: " + secret);          System.out.println("Decrypted: " + transpose.decrypt(secret));// Decrypt        }      }            abstract class Cipher {        public String encrypt(String s) {          StringBuffer result = new…

Using the following variable bindings: (setq x ‘(a b c d)) (setq y ‘(1 2 3 4)) Using only variables x and y, car, cdr, and cons, use Lisp expressions to generate:

Identify the errors in the following code segment * provide the correction for each error. Import Java.util.scanner; public class Readable { public Static void main(String[] args) { Scanner KB ; int shares; double averagePrice = 14.67; Shares = KB.nextDouble(); System.out.println("There were " , shares + " shares sold at $" + averagePrice + " per share."); } }
