Note:- Please type and execute this java program as soon as possible and also need an output for this java program.   1) This program counts the number of words in a sentence read from the keyboard   Variables: String str; char ch; int x; int count = 0; int length; boolean charBeforeWasPunc = false;   ask the user for a sentence read the sentence and store it in str get str length   loop str from x = 0 to length { use charAt() and store the xth character in ch if ch is a punctuation, such as , or . or ; or ! or ‘ ‘(Note that this is a space char, an empty single quote increment count if charBeforeWasPunc is true { decerment count set charBeforeWasPunc to true } otherwise set charBeforeWasPunc false } if not charBeforeWasPunc is true increment count   display count

Aim: Read a string, S and print its integer value. If S cannot be converted to   an integer, print Bad String.       '''       # getting the input   S = input().strip()   try:   # if it's possible to convert the entered string into an integer then this block will execute   print(int(S))   except:   # if it's not possible, then this block will be executed   print('Bad String')       '''       COMPLEXITY:       Time Complexity -> O(1)   Space Complexity -> O(1)       Sample Input 1:   3   Sample Output 1:   3   Sample Input 2:   SB   Sample Output 2:   Bad String       Explaination:   '3' as a string can be converted into the integer 3, whereas SB can't be   converted to an integer hence the 'except' block is executed and 'Bad String'   is printed.

Task 3. Remove white spaces and special symbols Program asks user to input a string to remove white spaces and special symbols (dashes, commas and dots). User inputs a string (with several words) and program prints out the input string without white spaces and special symbols. You may use Scan objects and loops. Example: Input a string to remove special symbols: hey, - i like may. Result: heyilikemay
