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)...

Lists: Create a list of student names. These are strings representing the names of
students in your class (e.g., ["John", "Mary", "Peter", "Sam"]).
2. Tuples: For each student, create a tuple that stores their grades in different subjects. The
subjects are Mathematics, English, and Science (e.g., (85, 90, 88)).
3. Dictionaries: Now, create a dictionary where the keys are the names of the students
(from your list), and the values are the tuples storing their grades. This way, you can
easily look up a student's grades in different subjects.
in pythonString full_string is read from input. Assign sub_string with full_string starting at index 5 to the end of the string.
True/False 7. The split method breaks a string into a list of substrings, and j oin does the opposite.
