Define a method named swapValues that takes an array of four integers as a parameter, swaps array elements at indices 0 and 1, and swaps array elements at indices 2 and 3. Then write a main program that reads four integers from input and stores the integers in an array in positions 0 to 3. The main program should call function swapValues() to swap array's values and print the swapped values on a single line separated with spaces. Ex If the input is: 3 8 2 4 function swapValues() returns and the main program outputs: 8 34 2 The program must define and call a method: public static void swapValues (int [] values)

In Java (Use the isPrime Method) PrimeNumberMethod.java, provides the isPrime(int number) method for testing whether the number is prime. Use this method to find the number of prime numbers less than 10000. Below are some clarifications for the Java program   (a) The lab is to COUNT the prime numbers less than 10000.  Do NOT list the prime numbers. (b) A pair prime is two prime numbers whose difference is 2. For e.g. 3,5; 11,13; 17, 19; etc. We can use IsPrime function to count how many pair primes are there in a range from 2 to 100 for example.  Create a function pairPrime, that takes one argument. pairPrime should return the number of pair primes between 2 and the argument passed. Use the pairPrime function to count the pair primes  between 2 and 1000.  Make use of the IsPrime  function to solve this task. (This feature is worth 8 points). Use the compile/run button to test tour program. Include the output displayed. It will be similar to: command>javac…

Please use java only. In this assignment, you will implement a simple game in a class called SimpleGame. This game has 2 options for the user playing. Based on user input, the user can choose to either convert time, from seconds to hours, minutes, and seconds, or calculate the sum of all digits in an integer. At the beginning of the game, the user will be prompted to input either 1 or 2, to indicate which option of the game they want to play. 1 will indicate converting time, and 2 will indicate calculating the sum of digits in an integer. For converting time, the user will be prompted to input a number of seconds (as an int) and the program will call a method that will convert the seconds to time, in the format hours:minutes:seconds, and print the result. For example, if the user enters 6734, the program will print the time, 1:52:14. As another example, if the user enters 10,000, the program should print 2:46:39. For calculating the sum of digits in an integer, the user will be…

How can I express the following situation in Java programming?   Orcs, Hobbits, and Tom Bombadil We have n-1 Orcs and n Hobbits who want to cross a river. We also have Tom Bombadil who wants to cross as well. Only Hobbits and Tom Bombadil can row the boat (don’t ask　me why!) At all times, the number of Hobbits on either side of the river must be greater or equal the number of Orcs on that side (unless there are no Hobbits on that side), or the Hobbits will be killed by the Orcs! If the boat holds 2, with n=4 or more, the problem has no solution. If the boat can hold 3, then up to n=5 can be solved. If the boat can hold 4, any number (n) Hobbits can cross. So -- if n = 1,2 or 3 - use a boat of size 2. If n = 4 or 5 - use a boat of size 3. If n > 5 use a boat of size 4. If n <0 invalid input if n = 0 no output.
