Consider the processWords method. Assume that each of its two parameters is a String of length two or more. public void processWords(String word1, String word2) {String str1 = word1.substring(0, 2);String str2 = word2.substring(word2.length() - 1); String result = str2 + str1; System.out.println(result.indexOf(str2)); } Which of the following best describes the value printed when processWords is called? (A) The value 0 is always printed.(B) The value 1 is always printed.(C) The value result.length() - 1 is printed.(D) A substring containing the last character of word2 is printed.(E) A substring containing the last two characters of word2 is printed.
I'm not allowed to use DateFormat. I need to use an int to have a numerical variable for the day and year and a string for the month. That's the part where I'm stuck. I already did the rest. Learn C# beginner programming - Simple code - Im stuck on the Date format. Im creating a int for 142021 and a string for the month name. Efficiently create your codes to display the correct formatted output below. 1. The program CANNOT have literal(s) within the method invocation operator for Write and WriteLine. 2. Except for the date (the last line), each output line is a string that will be assigned to a variable. 3. For the last output, you must use a numerical variable for the day and year. 4. Can only have ONE variable of each data type declared in the entire program. 5. No additional libraries are allowed. 6. Use standard variable naming convention. Should look like this:

Need help with this java problem. Some Websites impose certain rules for passwords.Write a method that checks whether a string is a valid password. The method must takes a password as a parameter and return a boolean value. If the password is valid, returns true, otherwise, return false. Suppose the password rules are as follows:- A password must have at least eight characters.- A password must contain only letters and digits.- A password must contain at least two digits. Please make sure you write a comment line to document what your method does. Write a program that prompts the user to enter a password, then call the method that checks the password, and displays "Valid Password" if the rulesare followed, or Invalid Password otherwise. The main program must allow the user to check multiple passwords. It should ask the user "Do you want to continue checking anther password (y/n)?"
Create an application with a method that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argument is "hello. my name is Joe. what is your name?" the method should return the string "Hello. My name is Joe. What is your name?" The application should let the user enter a string and then pass it to the method. The modified string should be displayed.

Write a method that convertsmilliseconds to hours, minutes, and seconds using the following header:public static String convertMillis(long millis)The method returns a string as hours:minutes:seconds. For example,convertMillis(5500) returns a string 0:0:5, convertMillis(100000)returns a string 0:1:40, and convertMillis(555550000) returns a string154:19:10. Write a test program that prompts the user to enter a long integer formilliseconds and displays a string in the format of hours:minutes:seconds.

Please use loop and add comment on each line. Thank you Write down a method named: hasTwoConsecutiveLetters() in Java, to check if the input (argument) string has two consecutive occurrences of the same letter (alphabetic characters). The method should be case insensitive. Write a test program that prompts user to input a string and invokes this method. Here is the sample run. Example: Enter an input string: aabcded Output: The input string aabcded has two consecutive same letters Enter an input string: ababab Output: The input string ababab has no two consecutive same letters Enter an input string: abbbabab Output: The input string abbbabab has no two consecutive same letters [Note: In the case above we will not consider bbb as there are three consecutive b’s, we only need to find instances where there are only two consecutive letters]
How do I create a code that has a public static method named replaceFirst that takes in a String s and a char c as arguments. The method will return a modified String replacing the first character with the one that was passed in. (Do not print out the String) Java
