Notes: 1) Ignore letter case; Uppercase and lowercase letters are considered the same. 2) Do not use methods from the Arrays class.T/F A Java main method uses the parameter (String[ ] variable) so that a user can run the program and supply“command-line” parameters. Since the parameter is a String array, however, the user does not have to supply anyparameters.when an individual array element of an array of type int is passed to a method, it is passed by reference.

- JAVA LANGUAGE Create an ArrayList, Name it YourRegNoandName that can hold Integers, and fill each slot with a different random value from 1-50. Display those values on the screen, and then prompt the user for an integer to search through the ArrayList, and if the item is present, say “FOUND”. It is not necessary to display anything if the value was not found. If the item is in the ArrayList multiple times, it's okay if the program prints the message more than once. ALSO SCREENSHOT THE OUTPUTFor Beginners Java: Write a program that ask the user to enter a list of positive scores until the user enters a negative score to terminate the input. You need to store these scores in an array. You can assume the maximum number of scores the user may enter is 50. However, you need to keep track of the actual number of scores entered. Write 2 methods: 1. calculateAverage(): this method takes the list of scores and return the average score. 2. countPerfectScores(): this method takes the list of scores and return the number of perfect scores (100). The main program reads the input and calls these methods and print the results. Please make sure you write a comment line to document what your method does.DNA Max Write code to find which of the strands representing DNA in an array String[] strands representing strands of DNA has the most occurrences of the nucleotide represented by parameter nuc. Complete the definition of the class DnaMax and method definition maxStrand shown below. If more than one strand has the same maximal number of the specified nucleotide you should return the longest strand with the maximal number. All DNA strands have different lengths in this problem so the maximal strand will be unique when length is accounted for. Return this uniquely maximal strand. Each String representing a DNA strand will contain only cytosine, guanine, thymine, and adenine, represented by the characters 'c', 'g', 't', and 'a', respectively. If no strand in the array contains the specified nucleotide return the empty string "". public class DnaMax { public String maxStrand(String[] strands, String nuc) { // fill in code here } } Constraints strands will contain no more than 50 elements,…
- JAVA program Write a Java program that asks the user to enter an array of integers. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0. Use Math.abs()JAVA program Write a Java program that asks the user to enter an array of integers. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0.Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
