Step by step
Solved in 2 steps
- Suppose that you declare two String objects as: String word1 = new String("Computer"); String word2 = new String("Science"); Write an if statement that checks to see if the two strings are equal.Please do not use string methods except to find methodTrue or False: The String class’s replace method can replace individual characters, but cannot replace substrings.
- Name format: You must use String object and not StringBuffer or StringBuilder. Many documents use a specific format for a person's name. Write a program that take one Line as an input. Example: Scanner input = new Scanner(System.in); System.out.println(“Enter firstName middleName lastName separated by at least one blank, It may have more than one blank separating firstName middleName lastName."); Input sample : Pat Silly Doe || Note these are separated by at least one blank. String line = input.nextLine() Ex: If the input is: Pat Silly Doe the output is: Doe, P.S. If the input has the form: firstName lastName the output is: lastName, firstInitial. Ex: If the input is: Julia Clark the output is: Clark, J. Please submit the .java source file and the sample run in a text file. ThanksGuessing game: Read a number until it's equal to a chosen number (first it can be a hard-coded constant or #define, or you can check rand() later). In case of wrong guessing help the user by printing whether the guessed number is to small or too big. ( in C language)The data type bool: Group of answer choices Can only be used in a selection statement. Can take on any expression as a value. Can take on values -1, 0 or 1. Can take on values true and false.
- Consider the following code segment: struct Dog { string name; int age; };…Dog x = { "Snoopy", 5 };Dog y = { "Bolt", 3 }; Which of the following is an invalid expression? Group of answer choices if (x == y) y = x; x.name = y.name; if (x.age < y.age)This code must be in Python: START OF PLAY The player starts with 100 points. They have ten attempts (or rounds) to reach 500 points to win. Each round, the player "bets" some amount of points. See gameplay as follows: A HIGH/LOW ROUND (1) The player is shown an initial random card.Cards have a value from 2-14; however, these values are converted to a string as follows: 2-9 are converted to their string equivalent "2", "3", ... "9"10 is "T", 11 is "J", 12 is "Q", 13 is "K" and 14 is "A" (2) After the play sees the first card, they should guess if the next card will be higher (i.e., greater than the current card) or lower (i.e., a lower value than the first card).They will do this by inputting "H" or "L" (lowercase "h" and "l" will also be accepted as valid input). (3) After they input their "high" or "low" guess, the player bets a number of points that their guess will be right. The bet must be between 1 and the total amount of points the player has.1 (4) After the bet amount is…Nice Number Programming: Nice program ask user to enter three integers from keyboard (java console), the three integers represent left bound, right bound and arbitrary digit 'm', where left bound is less than right bound. Program should print all nice numbers in the given range that doesn't contain digit 'm'. The number is nice if its every digit is larger than the sum of digits which are on the right side of that digit. For example 741 is a nice number since 4> 1, and 7> 4+1. with digit m=2. Write a complete program in Java that Call only One method (niceNumbers method) that will print all nice numbers excluding a given digit 'm' that also entered by user?
