Write a Program to take two strings from the user and find the common string in both of them. Try to give the very optimised approach, I know the brute force approach and try on two different test case. You can use Java as programming language.

Write a program that will read a line of text and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by either whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and periods. When outputting the number of letters that occur in a line, be sure to count uppercase and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that occur in the input line. For example, the input line I say Hi. should produce output similar to the following: 3 words 1 a 1 h 2 i 1 s 1 y

Write Java code to read strings of lower-case letters from the keyboard and count the number of vowels in each word. (vowels are a,e,i,o and u). When all strings have been read in, print the string that has the largest number of vowels (duplicates included) and how many vowels were in the string. When more than one string has the greatest number of vowels, print the first string found with that number. For example, with input of she groceries yourselves here radio, the correct answer would be: groceries – 4 vowels.

I have been working on writing a java program (that goes with another I just got finished- see below CollegeCourse & Student) that prompts user to put in letter grades (A-F) for 5 different courses for a total of 10 different students. So I need to prompt user to input a student ID, then the 1st course ID, then the grade, then the 2nd course ID- then grade, the the 3rd course ID then grade, then the 4th course ID then grade, then finally the 5th course ID then grade. Then it needs to go through the same thing 10 times (for a total of 10 students). It also says the user is asked to "Enter ID for student #s" where s is an integer from 1 through 10, indicating the student (and I don't really know how to do that but I tried as I googled java); AND "Enter course ID #n, where n is an integer from 1 through 5, indicating the course number. And last it needs to verify for grade entry that only the A, B, C, D, or F are entered.I started writing notes to try to keep track of where thing are…

Create a method in JAVA that returns a string when it receives three ints

How to write a program in java that ask the user for an input word(use the String method toUpperCase to convert the word to all upper-case characters), then have the program keep looping, generating random strings until the random string matches the user word and keep track of how many loops were required to match. Each time through the loop, your program should output the user’s word, the random string, and the difference score. The difference score is the sum of the absolute value of the difference between each character in the random string and the user’s input string. For example, if the random string was “ABC” and the target string was “AAA”, then the difference score is 3 (abs(A-A) + abs(A-B) + abs(A-C) = 0 + 1 + 2 = 3). You can get at the characters of a string, using the String charAt and absolute value is the abs method of the java.lang.Math class. To generate random strings, in a loop, generate random characters to build up a random string the same length as the user word. To…

Is there a way to create a java program on Branching and selecting method on problems like this? Suppose that we are working for an online service that provides a bulletin board for its users. We would like to give our users the option of filtering out profanity. Suppose that we consider the words cat dog and rabbit to be profane.  Write a program that reads a string from the keyboard and test whether the string contain any one of these words.  Your program should find words like cAt that differ only in case.   Have your program reject only lines that contain one or more of the three words exactly.  For example, concatenation is a small category should not be considered profane.    This problem can be solved easily.  If you add a space to the beginning of the string and a space at the end of the string you only need to check if space cat space or space dog space or space rabbit space is in the string. Use three if statements; one for each word. If one or more of the words are there set…

Write a method that reverses a string. For example, 'java interview' becomes 'weivretni avaj'.
