Question

write a java program that does the following

Part one

1. Use a For loop to compute the sum of all the odd numbers from 1 through 99. Your result should be labeled, and the value should be 2500.
2. Print your name 7 times using a While loop.
3. String dogNames[ ] = {"Sam","Buster","Fido","Patches","Gromit","Flicka"};
   Using the array defined here, print the values of the array vertically and horizontally using one For-Each loop.
4. Reverse the logic (Nested loops: Indent text) so that the first line is indented userNum number of spaces and the subsequent lines are each indented one less space until the last value is not indented at all (‘s’ indicates one space):
   sssss5
   ssss4
   sss3
   ss2
   s1
   0
5. String method practice:
   • Create a String variable that contains your full name
   • Repeat the following steps -- in other words, code a loop -- that repeats until you see all of the random values (hint: four boolean flags will work well here -- loop until all are true!) Also, you will use four, different predefined String methods to modify your name as indicated - see section 3.8 and 3.9 in our zyBook for examples:
     • Generate a random number between 1 and 4
     • If number is 1, replace your first name with "One" and display the result
     • If number is 2, display the length of the String variable that contains your full name
     • If number is 3, append " is a successful student!" to your full name and display the result (note there are two ways to do this so use the method; do not use the +)
     • If number is 4, display the character at index 4
6. Part two Create an array that will hold 4 string values. Write three separate statements to store your favorite color, your favorite song, and your favorite restaurant in the array elements. I do not want you to use a loop in this logic; use hard-coded index values instead. Print *ALL FOUR* of the values of the array using individual index values. What is stored in the element you did not fill? (type your answer in a single line comment within your program)
   
7. Create an array that will hold 5 string values. Use a for loop to prompt the user to enter their 5 favorite movies and store each one in a separate element of the array. Print the values of the array using a For-Each loop.

1. • Modify the array for steps part two to hold 3 String values instead of what we did before. This array should be created in the main method and passed into each method when called.

• make sure you include Javadoc comments on each method to describe 'what' the method does

package HomeworkLib;

public class Chegg_3rdMar {

   public static void main(String[] args) {
       int sum = 0;
       for (int i = 1; i < 100; i += 2) {
           sum = sum + i;
       }
       System.out.println(sum);
   }
