iven that an ArrayList of Strings named friendList has already been created and names have already been inserted, write the statement necessary to change the name "Tyler", stored at index 8, to "Bud".     This is needed in Java

Below is the code for a Time class that has both an equals method and a hashCode method; however, the body of the hashCode method is missing.  In the text box, write the code you would put inside the body of the hashCode method. Remember that a hashCode with no collisions is better than a hashCode that has collisions and a hashCode with no gaps in the values is better than a hashCode that has gaps. public class Time {     private int hour; // A number between 1 and 12     private int min; // A number between 0 and 59     private boolean pm; // True if the time is pm.       public Time(int hour, int min, boolean pm) {         this.hour = hour;         this .min = min;         this.pm = pm;     }       public int getHour() { return hour; }     public int getMin() { return min; }     public boolean isPM() { return pm == true; }     public boolean isAM() { return pm == false; }       public boolean equals(Object obj) {         if (this == obj)             return true;         if (obj ==…

Write a program in JAVA to input the number of elements in an array, also input the values in the array from the console. Replace all those elements which are even and greater than 5, with -99. Print the final array. Constraints: The array should initially not contain -99. The value of the number of elements should not be greater than 50.

Write a java code for this. Strings Read the paragraph and encrypt the content using the following rules; "The String, StringBuffer, and StringBuilder classes are defined in java.lang. Thus, they are available to all programs automatically. All are declared final, which means that none of these classes may be subclassed. This allows certain optimizations that increase performance to take place on common string operations. All three implement the CharSequence interface." RULES The words ‘the’, ‘and’, and ‘for’ should be replaced by their reverse strings in upper case letters (use predefined functions reverse() and toupper()) The first occurrence of the word ‘are’ should be replaced by ‘AREERA’ and the last occurrence of the word ‘of’ to be replaced by ‘123’.

4. Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print them to the console. What would the code look like for this? 5. Write a method signature for a method called foo that takes an array as an argument. The return type is void. 6. What is the difference between remove and clear in ArrayLists.

Provide a different implementation of ChoiceQuestion. Instead of storing the choices in an array list, the addChoice method should add the choice to the question text. For this purpose, an addLine method has been added to the Question class. Use the following files: Question.java /**   A question with a text and an answer.*/public class Question{   private String text;   private String answer;    /**      Constructs a question with empty text and empty answer.   */   public Question()    {      text = "";      answer = "";   }    /**      Sets the answer for this question.      @param correctResponse the answer   */   public void setAnswer(String correctResponse)   {      answer = correctResponse;   }    /**      Checks a given response for correctness.      @param response the response to check      @return true if the response was correct, false otherwise   */   public boolean checkAnswer(String response)   {      return response.equals(answer);   }    /**      Add a line of text to…

Intellij - Java Write a program which does the following: Create a class with the main() method. Take a string array input from the user in main() method. Note: Do not hardcode the string array in code. After the String array input loop, the array should be: words[] = {"today", "is", "a", "lovely", "spring","day", "not", "too", "hot", "not", "too", "cold"}; Print the contents of this array using Arrays.toString() method. Write a method called handleString() that performs the following: Takes a String[] array as method parameter (similar to main method). Loop through the array passed as parameter, and for each word in the array: If the length of the word is even, get the index of the last letter & print that index. Use length() and indexOf() String object methods. If the string length is odd, get the character at the 1st position in the string & print that letter. Use length() and charAt() String object methods.

First, implement a python class called Student. This class should store 2 variables, name and grade. Later, implement a class called Classroom. The constructor of this class should input the list of students in this classrom. This class should also contain 3 methods, add_student, remove_student and calculate_stats. As the names suggest, add_student method should input a Student object and add that to its' already existing student list, remove_student must input a full name(string) and delete the student with the provided name(you can assume no 2 students have the same full name). Finally, calculate_stats method must calculate and print the following statistics of the grades: 1. The name of the student with highest grade and the grade itself. 2. The name of the student with lowest grade and the grade itself. 3. The average grade
