Explanation of Solution
Statement to change first lowercase character to uppercase character:
Assume each and every element in list is considered as a StringBuilder, statement to change the first character to uppercase for each element in 1ist using a forEach method is given below:
Statement:
//Use forEach() method
l1.forEach(e -> {
/*Check whether the length of StringBuilder is greater than 0 */
if (((StringBuilder)e).length() > 0) {
/*Declare variable and initialize with "0" index of StringBuilder */
char ch = ((StringBuilder)e).charAt(0);
//Check whether character is lowercase character
if (Character.isLowerCase(ch)) {
/*Change the first lowercase character to uppercase character */
((StringBuilder)e)...

- WAP c# program creates a string, s1, which deliberately leaves space for a name, much like you’d do with a letter you plan to run through a mail merge. We add two to the position where we find the comma to make sure there is a space between the comma and the name.arrow_forwardTrue/False 7.

- def q5(sentence): Assumes sentence is a string. Returns a list of all the words in sentence, where a word is a token separated by white space, (you can use sentence.split()), and then for each word, make it lowercase and remove any character that is not alpha-numeric (a-z or 8-9). For example, I q5("The Plague" (French: "La Peste"), 1947, by Albert CamUs.') should return ['the', 'plague', 'french', 'la', 'peste', '1947', 'by', 'albert', 'camus'] q5('Red@Dragon....ca is great!') should return ['reddragonca', 'is', 'great'] passarrow_forwardWrite a statement, using pyhton language, that creates a two-dimensional list with 5 rows and 3 columns.

The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1 below.
