Write a program that generates a random string with six lower-case letters.
1. Write a program that reads a number between
1,000 and 999,999 from the user, where the
user enters a comma in the input. Then print
the number without a comma. Here is a sample
dialog; the user input is in color:
Please enter an integer between 1,000
and 999,999: 23,456
23456
Hint: Read the input as a string. Measure the
length of the string. Suppose it contains n
characters. Then extract substrings consisting of
the first n - 4 characters and the last three
characters.

2. Writing large letters. A large letter H can be
produced like this:
*
It can be declared as a string literal like this:
final string LETTER_H = "* *%n*
*n*****n* *n* *%n";
Print the string with System.out.printf. The
en format specifiers cause line breaks in the
output. Do the same for the letters E, L, and O.
Then write in large letters:
O
3. Write a program that transforms numbers 1, 2,
3,..., 12 into the corresponding month names
January, February, March, ..., December.
Hint: Make a very long string "January…

- Write a program that reads a string and checks the longest substring starting with "a" and ending with "z" included in it. Note that, the substring cannot contain another a or another z in it. For example: Ifs="bcd bbccdd badefgze tabdz", the longest substring is: 6arrow_forwardWrite a program that reads the full name of a student; and then prints it in the form: last first middle initial. Example: Input: Ali Hamad Al-Harbi Output: Al-Harbi, Ali H. Write a program that reads a string composed of three words separated by a space, and then print each word on a separate line. Input: one two three Output: One two threearrow_forwardWrite a program that reads a text (string) and prints the letter that starts the most number ofwords in that stringarrow_forward
- Java with out string formarrow_forwardWrite a program that reads in a string containing three words separated by commasand then outputs that string with each word in a different line.arrow_forwardWrite a program to print all the unique characters in a String. For instance, if the input string is “abcb”, the output will be the characters ‘a’ and ‘c’ as they are unique. The character ‘b’ repeats twice and so it will not be printed.arrow_forward
- Design a program that asks the user to enter a string and then converts that string to Morse code. Morse code is a code where each letter of the English alphabet, each digit, and various punctuation characters are represented by a series of dots and dashes.arrow_forwardWrite a program that asks the user to enter a word that contains the letter a. The program should then print the following two lines: On the first line should be the part of the string up to and including the first a, and on the second line should be the rest of the string. Sample output is shown below:Enter a word: buffalo buffa loarrow_forwardIn Java write a program to read Input a string and find number of lowercase alphabets in it.arrow_forward
- write a program that prompts the user toenter a string and displays the number of vowels and consonants in the string. Assume lettersA, E, I, O, U (or a, e, i, o, u) as the vowels.1. Prompt the user for a String. (Note: The user input String may contain spaces)2. Print the number of vowels and consonants in the String. The count displayed mustaccount for all the vowels and consonants in the String regardless of case (upper orlower case). You must use a loop in your solution.Hint: charAt(index) and length() method for the String, toUpperCase(ch) (ortoLowerCase(ch)), isLetter(ch) method for the Character is helpful for thisassignment3. The output from the program must be enclosed in quotes as shown below in the samplerun of the program.arrow_forwardWrite a program that generates the positions of whitespaces in a string and prints them on the screen. For example given the following string as input: "hello there my friends" the program should generate: 5, 11, 14arrow_forwardYour task is to take 2 strings from the user and then check whether All occurrences of a character of a string must be replaced with another character of another string while preserving the order of characters of strings.
