- To create a method that would give me a nicely formatted display of my information in accordance with standard convention, which method header should I use? public String tostring() public static String tostring() public String toString() public static String toString() in javaModify the program below to create a class that contains a static method; the method takes a string as a parameter and returns a boolean value indicating whether the parameter string has repeated characters in it or not. That is, return true if there is at least one character which appears more than once in the string. The string should be input by the .user import java .util.*; public class Main{public static void main(String args[]){Scanner scn=new Scanner(System.in); // Input the string from userSystem.out.println ( "Enter the String to check for duplicate characters:");String str = scn.next();// Check is variable to store bool value true// It will change to true if there are repeated charactersboolean check=false;for (int a = 0; a < str.length(); a++)for (int b = a + 1; b < str.length(); b++)if (str.charAt(a) == str.charAt(b))check=true;// If check is true then string has repeated characters if (check)System.out.println("The String " + str + " has repeated…What value is returned from the following method? public static double methodA() { double a = 8.5 + 9.5; return a; }
- What is wrong with each of the following method headers? a. public static void print(String... strings, double... numbers) b. public static void print(double... numbers, String name) c. public static double... print(double d1, double d2)Write a method that prints your name in the Java programming language. The name should be saved in the variable named "name".The variable name should be a CONSTANT with your name, select the appropriate type of the variable!The program should print out the name in original and reversed order!Create a Java program that contains a String that holds your favorite inspirational quote. Pass the quote to the calculateSpaces method and return the number of spaces to be displayed in the main method. public class CountSpaces { public static void main(String[] args) { // write your code here } public static int calculateSpaces(String inString) { // write your code here } }
- MethodsJava Write the appropriate method headings using the provided method name for the following processes:1.) Given the radius of a circle, print the area of a circle - printArea. 2.) Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeString 3.) Calculate and return the sum of two decimal numbers - getSum. 4.) Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails. 5) Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed.Find out the output of the following code snippet? class OverloadingCalculation3{ void sum(int a,long b){System.out.printin("a method invoked");} void sum(long a,int b){System.out.printin("b method invoked");} public static void main(String args[]){ OverloadingCalculation3 obj=new OverloadingCalculation3 () ; obj.sum(20,20); } }Where do I place a return method for finding the area of a square, triangle, and rectangle? Also are the math equations correct for each shape? //PSEUDOCODE //Write a program that demonstrates method overloading by defining and calling methods that return the area //of a triangle //a rectangle //a square private static void area(float a) { System.out.println("The area of the square is " + String.format("%,.2f", Math.pow(a,2)) + " sq units"); } private static void area1 (float a, float b) { System.out.println("The area a of the rectangle is " + String.format("%,.2f", a * b) + " sq units"); } private static void area (float a, float b) { double c = 0.5 * (a * b); System.out.println("The area of the triangle is " + String.format("%,.2f", c) + " sq units"); } public static void main(String[] args) { area(5); area1(05,21); area(05,05); } }
- Create a method in java that takes a value and indicates whether it is positive or negative by a return a Boolean value. Declared as: boolean is positive (float a) (with a screenshot of the code please)Which of the following methods is necessary for a Java class to be a program? A. static void main(String[] args) B. public void main(String[] args) C. public static void main(String[] args) D. public final main(String[] args)java In a class method (a method declared as static) can instance variables from the same class be used? Choose one of the options:TrueFalse
