- In java: Develop a void function that takes two parameters, an integer and a string. The function should print the string as many times as given by the integer. For example, with arguments 4 and “Hello” the function would print “Hello” four times. Call the function twice with different arguments. What happens when the argument is negative?Write a Java program that asks the user to enter a string and counts how many times the letter "s" or "S" appears in the string. Display that number and then display the string that many times. Requirements: Call a method that gets the string from the user. Use recursion to ensure the string has at least 5 characters. Call a method that returns the number of times the letter "s" or "S" appears in the string. This method should use recursion. Call a method that takes the number of times the letter"s" or "S" appeared in the string and display the original string that was obtained from the user that many times using recursion. Call a method that sorts the letters in the string and searches for the letter "m". Display Found or Not Found.Swap two integer numbers without using third variable. In java please
- The following problem shows up in a number of Java texts, including Savitch's textbook: The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR. The calories needed for a woman to maintain her weight is: WBMR = 655 + (4.3 × weight in pounds) + (4.7 × height in inches) − (4.7× age in years) The calories needed for a man to maintain his weight is: MBMR = 66 + (6.3 × weight in pounds) + (12.9 × height in inches) − (6.8 × age in years) A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input his or her weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age. NOTE: This is an application of a selection statement! Input Data: Use a named constant for the…Have a research on the use of the Math methods and write a program that uses Math method. Use at least 10 methods. Using recursion, write a program that tells whether a number is palindrome or not Write a Java program that determines whether a positive integer is a prime number. Use a method that reads positive integer, second method that returns true if the number is prime; otherwise returns false and a method that prints a message telling whether is a prime number or not. Sample Output: Positive Integer: 73 73 is a prime number Have a research on the use of the Date and Time methods and write a program that uses Date and Time method. Use at least 3. Have a research on the use of the String methods and write a program that uses String method. Use at least 10.Use java Only. Introduction: The equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance…
- Write a Java program that inputs three integer variables (called a, b, and c) that represent the length of the sides of a triangle. Your program should store the type of the triangle in an enumeration variable (called type), and display the value of the variable type. Here are the steps to follow: 1- Defines an enumeration to represent the different triangle types: EQUILATERAL, ISOSCELES, SCALENE, and ERROR. The type ERROR is added in case that the value of any triangle sides is less than or equal to zero. 2- Declare then input the three integer variables a, b, and c using a scanner object called keyboard. 3- Declare the enumeration variable type. 4- Determine the type of the rectangle (i.e. Assign a value to the variable type) 5- Print the value of the variable type. NOTE: If all sides are equal, the rectangle is EQUILATERAL. If only two sides are equal, the rectangle is ISOSCELES, otherwise the rectangle is SCALENE. Note that the type of the rectangle should be ERROR if the length…In Java: Develop a void function that takes two integers and prints whether the first number is divisible by the second. For example, with arguments 51 and 17, the function should print “51 is divisible by 17”. With arguments 17 and 8, the function should print “17 is not divisible by 8”. Call the function twice with different arguments to show each possible result. What happens when the second argument is greater than the first?I have two matrices, for example, as follows: Matrix 1: 2 4 3 1 6 7 5 8 9 Matrix 2: 5 5 3 1 6 6 5 3 8 Write a program to check if these two matrices are the same (i.e. to see if each number in matrix 1 equals to its corresponding number (same row same column) in matrix 2). If they are the same, display “same matrices”; otherwise display “different matrices”. Using java programming
- Write a Java method that generates and returns a random number between 2 valuesreceived as parameters. You must consider 2 cases when there are or not differencebetween values (please refer to slide 43 from 04 Methods). The function should checkif the difference is strictly positive otherwise replace it with the value 1.Test your method using main as follows (bold values are input by the user):Lowest value: 60Highest value: 100Diff. between values: 5Number of random numbers: 5060 90 70 65 70 60 75 100 100 8580 90 60 95 75 65 80 70 90 9085 65 95 60 85 95 75 85 60 7090 80 65 65 90 90 80 60 95 7560 90 70 70 90 60 65 60 85 60An isolated hydrogen atom emits a photon of x eV.
