write code in java that can take an input from the command line, which will be a sentence with improper capitalization. For example "joey DoEsnt Like cAts. HoWeveR She doES." and the code is supposed to fix all the capitalization errors. I am stuck on how to approach this problem.

Write a program to build a calculator. Instead of a typical calculator which reads in-order expressions and evaluates them, build a calculator that takes in numbers and assigns the operations to yield the highest value expression. The current operations on the calculator only handle pairs of parentheses, and the operators for addition, subtraction, multiplication, and division. The calculator can rearrange the numbers if it helps find the optimal value. For example, the list:4.0 5.0 3.0 2.0 1.0using the calculator should find the optimal expression yielding the maximum value to be:4.0 * 5.0 * 3.0 * (2.0 + 1.0) = 180Input from the keyboard a list of up to 10 floating-point values from-100000.0to100000.0. Output to the screen a single floating-point value rounded to two decimal places representing the highest value expression that the calculator could create by inserting the symbols( ) + - * /into the given expression. Assume at least one number in the list and only the operators listed…

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…

In Java Write a program that checks the properness of a given variable name. Morespecifically, your program should specify whether a user-entered variable nameis (1) illegal, (2) legal but uses poor style, or (3) good. There are differentopinions as to what constitutes a good style for a variable name. For thisprogram, check for good style using these rules:· Only use letters and digits.· Use a lowercase letter for the first character.You do not need to check for an uppercase letter for the first letter in the secondand third words, ...etc.Your program should repeatedly prompt the user for variable names until the userenters "q" or "Q." the program terminates when the user enters the "q" or "Q."  Sample session:This program checks the properness of a proposed Java variable name.Enter a variable name (q or Q to quit): streetAddress2Good!Enter a variable name (q or Q to quit): street address2Illegal.Enter a variable name (q or Q to quit): StreetAddress2Legal, but uses poor style.Enter a…
