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.

- Art.java In this part you will create a program Art.java that produces a recursive drawing of the design attached in the picture. Requirements Art.java must take one (1) integer command-line argument n that controls the depth of recursion. Your drawing must stay within the drawing window when n is between 1 and 7. (The autograder will not test values of n outside of this range.) You may not change the size of the drawing window (but you may change the scale). Do not add sound. Your drawing can be a geometric pattern, a random construction, or anything else that takes advantage of recursive functions. Optionally, you may use the Transform2D library you implemented in Part 1. You may also define additional geometric transforms in Art.java, such as sheer, reflect across the x- or y- axis, or rotate about an arbitrary point (as opposed to the origin). Your program must be organized into at least three separate functions, including main(). All functions except main() must be private. call…PROBLEM STATEMENT: An anagram is a word that has been rearranged from another word, check tosee if the second word is a rearrangement of the first word. public class AnagramComputation{public static boolean solution(String word1, String word2){// ↓↓↓↓ your code goes here ↓↓↓↓return true;}} Can you help me with this java question the language is java please use the code I gavelight } What is the output of this Java program? } class Driver { public static void main(String[] args) { int a = 6: int b = 6; int c = 5; int x = 1; if (a > 2) { } } if x = x + 600; (b> 3) { x = x + 60; } if (c < 9) { X = x + 5; System.out.print(x);
- JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.) import java.util.*; public class TestCipher { public static void main(String[] args) { int shift = 7; Caesar caesar = new Caesar(); String text = "hello world"; String encryptTxt = caesar.encrypt(text); System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt); } } abstract class Cipher { public String encrypt(String s) { StringBuffer result = new StringBuffer(""); // Use a StringBuffer StringTokenizer words = new StringTokenizer(s); // Break s into its words while (words.hasMoreTokens()) { // For each word in s…void main (void) { char result = a; for (char i = { 10; i > 5; i = i-1) result = result + i; } // point B } Consider the code above. What is the decimal value of "result" at "point B" if the variable "a" is initially 59?// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…
