- 1. Write a Java program that will ask for a string of letters . 2. Each letter in the alphabet is given the following number code as assignment . 3. Print out the number code of each letter from the input in reverse . 4. Ask if the operation should be done again, if Yes, Return to 1. if No. Terminate the program 5. Create at least 2 methods aside from your main method in implementing a solution for this problem.Java allows for methods to be chained together. Consider the following message from the captain of a pirate ship: String msg1 = " Maroon the First Mate with a flagon of water and a pistol! "; We want to change the message to read the message msg1: String msg2= “Maroon the Quartermaster with a flagon of water.” Three changes need to be made to adjust the string as desired: Trim the leading and trailing whitespace. Replace the substring First Mate with Quartermaster. Remove "and a pistol!" Add a period at the end of the sentence. Need a java file Chaining.java that will declare the above and creates two methods to do the followings: A “chaining1” method which will apply in sequence 4 operations to perform the above. We will use the trim, replace, and substring methods, in this order. Thus the chaining1 method will receive a string msg1 and return a string msg2. Make sure msg2 is printed. A “chaining2” method which will apply the 4 operations above in one single statement. Thus the…Java allows for methods to be chained together.

- Write a Java method that receives an int as input and returns true if the input parameter is 100 and false otherwise. 4.Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.in Java write a not on the method parameter and with return type .Given an exaple.
- Write java method fullName with a return type of void and accept a name. The method will display the abbreviation of the firstname and middle name except for the lastname. For example, if name is Yule Plaza Sanchez it will display: Y.P.Sanchez For example: Test Result fullName("Yule Plaza Sanchez"); Y.P.Sanchez fullName("Yule Josef Plaza Sanchez"); Y.J.P.SanchezWrite in Java. Write a method with the following header to format the integer with the specified width. public String format(int number, int width) The method returns a string for the number with one or more prefix 0s. The size of the string is the width within the range [1 to 10000]. For example, format(34, 4) returns 0034 and format(34,5) returns 00034. If the number is longer than the width, the method returns the string representation for the number. For example, format(34, 1) returns 34. Assume that, the size of the string is the width within the range [1 to 10000] and the number is an integer [-2147483647, 2147483647 ] You can assign tasks to multiple private methods. Input: 34 4 Output: 0034 ------------------------ Input: 34 1 Output: 34 Some Notes: 1- if the number of digits of the "number" is less than requested zeros, you need to add zero to the output, for example Input: 0 4 Output: 0000 2- Test your code for large numbers and also negative numbers as well Input:…I have to write a method with the header: public void duplicateTheBag() This method copies the contents of the bag. For example if the bag had (a,b,c) and you used the duplicateTheBag() method, the bag would contain (a,b,c,a,b,c). The order does not matter. This has the be in Java
- Add a static method, public static void changeLetter (StringBuilder sb, char letter) Convert all occurrences of the letter variable in the StringBuilder to upper case. Write in java and use test case example as reference.Write a method (with a parameter n), n: integer type that prints numbers from 1 to n. The print out should be 5 numbers per line. All the output numbers should be aligned well. Call the method with n=13 and n=10 in the main()Please write in JAVA In the Print class, implement a static method named printNumbers that will print out numbers in brackets, formatted as [1][2][3], and so on. The method should accept two integer parameters: howMany and lineLength. The signature of the method should be “public static void printNumbers(int howMany, int lineLength)”. The method should print numbers from 1 to howMany in the previous format, but it should not output more than lineLength characters on any one line. It should not start a [ unless it can fit the corresponding ] in the same line. Some sample inputs and expected output is shown below.
