- Language:Java - Requests two double values from the user and stores them in local variables in main() - Create a method which takes these two values as parameters- The method will use Math library functions to: o Print the square root of the 1st parametero Print the log of the 2nd parametero Print the value of the 1st parameter raised to the power of the 2nd parameterCorrect the following wrong statements. In Java, once a variable is declared in a method as local variable, it will be visible and could be used in any other method in the program.Class Utilities { Method Details addDelimiter: public static java.lang.String addDelimiter(java.lang.String str, char delimeter) Returns a string where characters are separated by the specified delimeter character. A string with a single character will not have a delimeter added. The space character is consider a character (similar to character 'A'). You can assume str will never be the empty string. You may not use an auxiliary method in order to implement this method. Your implementation must be recursive and you may not use any loop construct. Note: In java given two characters a and b, a + b will not create a string. To create a string, append a to the empty string and the result to b. From the String class, the only methods you can use are length(), isEmpty(), charAt() and substring. Do not use ++ or -- in any recursive call argument. It may lead to an infinite recursion. For example, use index + 1, instead of index++. Parameters: str - delimeter - Returns: String with characters…
- For the 8 Java statements below, identify each of the following statements as legal or illegal, and whether legal or not, state whether it represents a "narrowing" or "widening" conversion, or neither.Correct the following wrong statements. 1. do … while repetition statement gives full control on the code block to be repeated.2. In Java, once a variable is declared in a method as local variable, it will be visible and couldbe used in any other method in the program.3. All binary operators except for the assignment operators are evaluated as user intention.4. In Java, byte code is translated to native code by java compiler.5. Each row in a single dimensional array could be dealt with as 2-dimensional array.6. The indices of elements in a single dimensional array named arrElem are from 1 toarrElements[]length.7. In Java, method overloading means that a program may contain more than one methodwith same signatures. Each column in a 2D array could be dealt with as 1D array.8. The following statement creates and initializes the 2-dimensional array values:short values[][] = {10, 20, 30, 40, 50};9. A ragged 2D array is a 2D array in which each row may contain the same number ofcolumns.10.…Exercise 1Write a Java method random that generates and returns a random number between 14 and 59(using SecureRandom). Test your method several times using a main function
- JAVA Notes: all program codes should be written with method/s separated from the main() structure. Use a separate code files for each. Programming Problems: 1. Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, otherwise return false. Also write a program to test your method. 2. Write a program that prompts the user to enter a sequence of characters and output the number of vowels and consonants separately. (use the method isVowel written in problem 1). 3. Write a program that output inflation rates for two successive years and whether the inflation rates are increasing or decreasing. Ask the user to input the current price of an item and its price, one year and two years ago. To calculate the inflation rate for a year, subtract the price of the item for that year and from the price of the item from one year ago and then divide the result by the price a year ago. Your program must contain a method to calculate the results. Use…A primitive variable is passed from one method to another method by in Java. pass by value O pass by referenceJAVA PROGRAM Can You Please describe the method overloading on the subtraction of two numbers.
