I'm trying to write a program that takes in a positive integer as input, and output a string of 1’s and 0’s representing the integer in binary. Below is what i have coded so far, and im having trouble calling my metods in main. Please explaine what i am doing wrong. -------------------------------------------------------------------------------------------------------------------------------------------------------- import java.util.Scanner; public class binaryConversion { public static String integerToReverseBinary(int userInput){ String binaryString = ""; while(userInput != 0 ){ int binary = userInput % 2; binaryString = binary + binaryString; userInput = userInput / 2; } return binaryString; }//method public static String reverseString(String binaryString){ char [] letters = new char[binaryString.length()]; int letterIndex = 0; for (int i = binaryString.length() - 1; i >= 0; i-- ){ letters[letterIndex] = binaryString.charAt(i); letterIndex++; } String reverse = ""; for ( int i = 0; i < binaryString.length();i++){ reverse = reverse + letters[i]; } return reverse; }//method public static void main(String[] args) { Scanner scnr = new Scanner(System.in); //Variables int userInput; String rev; String string; //prompt the user to enter the integer that they would like to convert to binary System.out.println("Enter the number that will be converted: "); userInput = scnr.nextInt(); System.out.println(userInput+ " Converted to binary is: "); integerToReverseBinary(userInput); System.out.println("Number converted to binary: "+ binaryString); System.out.println(""); System.out.println(userInput + "Represented in reverse binary is: "); rev = reverseString(binaryString); System.out.println("The binary numbers in reverse are: " + reverse); scnr.close(); }//main }//Class
