Write a static method in Java that takes two integers n, and d as input parameters and returns the count of the digit d in the input integer n. The input parameters n and d will always be greater than 0.

Define a method printStateInfo() that takes two string parameters and outputs as follows, ending with a newline. The method should not return any value. Ex: If the input is MA Massachusetts, then the output is: ++ MA ++ is Massachusetts's state code

Write the following programs in Java: In the Converter class write the static method, bin2decimal(String bin). The parameter for this method is an unsigned (nonnegative) binary number represented by a string. The method returns the decimal equivalent for the binary parameter, as an integer.If the binary string is invalid (contains characters other than ‘0’ and ‘1’), the method returns -1. Convert from a binary (b) string with up to 16 digits to decimal (d) using the following formula:? = ?0 + ?1 × 2 + ?2 × 22 +⋯+ ?7 × 215where b0, b1, ?2, … ?7 are the binary digits in order of increasing significance. For example, 1101 is: 1 + 0×2 + 1×22 + 1×23 = 13 in decimal. Side note: You may NOT use the decode method of the Long wrapper class instead of this formula.   In the Converter class write another static method, english2encrypted(String english). The parameter for this method is a word or sentence represented by a string. The word or sentence should only contain letters (no digits,…

Write a Java application that calculates the sum of a series of integers that are passedto method sum() using a variable-length argument list. Test your method with severalcalls, each of which with different number of arguments

Write a java method called sumRange that accepts two integer parameters that represent arange. Issue an error message and return zero if the second parameter is less than the first.Otherwise, the method should return the sum of the integers in that range (inclusive).

Write a Java program to make two arrays containing random integer values (You can make these arrays with specific sizes using the below makeRandomArray method). The program should sum these two arrays and prints the resulted array (the array that contains the result of the two arrays summing). The program should also show the maximum element of the resulted array. Your program must define and call the following methods to perform the program as illustrated above: 1- A method int [] makeRandomArray(int size ,int a , int b) that makes and returns an array with specific size. The methods fills this array with random integers in a range [a..b] 2- A method public static int findmax(int x[ ]) that finds the maximum value of a number of x array passed to the method. 3- A method public static void printArray(int x[ ]) that prints the elements of the array x passed to the method. 4- A method public int[ ] sumTwoArrays(int x[ ], int y[ ]) that sums the elements of the two arrays(x and y…

Need help with following Java method: import java.util.Scanner; import java.lang.Math; public class CosineFromScratch { /* The following code demonstrates how to estimate the cosine of a number. Your assignment is to migrate the calculation of the cosine into a new static method named cosine. The method should take one double input and return one double output. Make sure to call the method from main and set the variable estimate equal to the returned value. */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nGive me a number: "); double x = input.nextDouble(); //Trying to find cosine of this number double correct_cos = Math.cos(x); //START HERE: The following code goes into //the method. //Source for the following: //https://austinhenley.com/blog/cosine.html double num_terms = 10; int div = (int)(x / Math.PI); x = x - (div * Math.PI); int sign = -1; double estimate = 1.0;…

I need help creating a code below   -  Write a recursive method called digitCount() that takes a positive integer as a parameter and returns the number of digits in the integer. Hint: The number of digits increases by 1 whenever the input number is divided by 10. Ex: If the input is: 345 the method digitCount() returns and the program outputs: 3

Given two sorted arrays, your task is to merge them in a new sorted array. Write a complete program in Java that takes two stored arrays of integers, and then calls a method that merges the two sorted arrays into one array that is sorted. The method returns a new array made by merging the two input sorted arrays. Note that the input arrays can be of different sizes. Assume that the size of each input array is given. You can NOT write a sorting algorithm or apply sorting. To clarify: You cannot merge the two arrays into one and then just sort it using a sorting algorithm. Examples: Input : arr1 = { 1, 3, 4, 5} arr2 = {2, 4, 6, 8} Output : arr3 = {1, 2, 3, 4, 5, 6, 7, 8} Input : arr1 = { 5, 8, 9} arr2 = {4, 7} Output : arr3 = {4, 5, 7, 8, 9}
