(language: Intellij-Java)
Part One: Create a method which takes two int parameters and swaps them. Print the values before and after swapping. (Example: ‘before swap: x = 5, y = 10; after swap: x=10, y=5).
Part2: Write a method which gets a value from the user and convert that value from Celsius to Fahrenheit:
- For Celsius to Fahrenheit conversion use: F = 9*C/5 + 32
- Print the result of the conversion
Part3: Create a method which takes an integer array input from the user and reverses the elements in the array. Print the reversed array.
- For example, the expected “reversed” result for an array [5,33,0,8,2] is [2,8,0,33,5]
- Don't use any inbuilt/existing array reverse method. Try to write the reversing logic
(Check password) Some websites impose certain rules for passwords. Write a
method that checks whether a string is a valid password. Suppose the password
rules are as follows:
A password must have at least eight characters.
A password consists of only letters and digits.
A password must contain at least two digits.
Write a program that prompts the user to enter a password and displays Valid
Password if the rules are followed or Invalid Password otherwise.
(Game: ATM machine) Use the Account class created in our previous Lab Exercise
to simulate an ATM machine. Create ten accounts in an array with id 0, 1, . . ., 9,
and initial balance $100. The system prompts the user to enter an id. If the id is
entered incorrectly, ask the user to enter a correct id. Once an id is accepted, the
main menu is displayed as shown in the sample run. You can enter a choice 1 for
viewing the current balance, 2 for withdrawing money, 3 for depositing money,
and 4 for exiting the main menu. Once you exit, the system will prompt for an id
again. Thus, once the system starts, it will not stop.

Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article, noun.As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forward
- (Computer-Assisted Instruction) The use of computers in education is referred to as computer-assisted instruction (CAI). Write a program that will help an elementary school student learn multiplication. Use a Random object to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate method should be used to generate each new question. This method should be called once when the application begins execution and each time the user answers the question correctly.arrow_forward(True/False): In protected mode, each procedure call uses a minimum of 4 bytes of stackspace.arrow_forward(Financial application: payroll) Write a Java program that reads the following information and prints a payroll statement:arrow_forward
