Is any one like to fix my while loop. Its not working right. when I called my method name decimalToBinary(input)) in the while loop its giving me error like I need to change the int type to String. but I want the user to put an integer and get converted to binary. And the loop is not working properly or what I intended to do so please help!
import java.util.Scanner;
import structures.ArrayStack;

public class StackApps {
private static Scanner userInput;
public static void main(String[] args) {
boolean flag = false;
while (!flag) {
System.out.print(\"Please enter the Integer number to convert:(Enter x to exit): \");
Scanner userInput = new Scanner(System.in);
final String input = userInput.next();
while(!(input.equals(\"x\"))){
int num2 = 0;
userInput = new Scanner(System.in);
try {
input = userInput.next();
num2 = Integer.parseInt(input);
} catch (NumberFormatException ex) {
System.out.println(\"Please enter only an integer number.\");
}
if(num2 < 0) {
System.out.println(\"Please enter a postive number > 0.\" );
} else {
System.out.println(decimalToBinary(input));
}
System.out.println(\"Whould you like to continue? \'Y\' or \'N\'\");
Scanner yesOrNo = new Scanner(System.in);
final String prompt = yesOrNo.next();
if (\"Y\".equals(prompt) || \"y\".equals(prompt)) {
flag = false;
