Question

Have to write a program in Java for an ATM however when compiling after enter w nothing happens.

import java.util.Scanner;
public class ATMMain {
   public static void main(String[] args) {
   double Ibalance = 5000, usermoney, withdrawB, depositD;
   String userFname = "X";
   String userLname = "X";
   String w, d, e, c;
   System.out.println("Welcome");
   Scanner input = new Scanner(System.in);
       System.out.println("Welcome" + " " + userFname + " " + userLname);
       System.out.println("your current balance" + " " + Ibalance);
       System.out.println("Enter in w = withdraw, d = deposit, c = check, or e = logout");
       w = input.next();
       d = input.next();
       e = input.next();
       c = input.next();
       System.out.println("enter amount");
       usermoney = input.nextDouble();
      

if(input.next() == w) {
   System.out.println("How much do you want to withdraw");
       withdrawB = Ibalance - usermoney;
       System.out.println(withdrawB);
}
else if(input.next() == d) {
   System.out.println("How much do you want to deposit");
       depositD = Ibalance + usermoney;
       System.out.println(depositD);
}
else if (input.next() == c) {
           System.out.println(Ibalance);
       }
       else if (input.next() == e) {
               System.out.println("logging out");
           }
       else {
       System.out.println("invalid input");
       }
switch (input.next()) {
case "w":
       System.out.println("w");
       break;
case "d":
       System.out.println("d");
       break;
case "c":
       System.out.println("c");
       break;
case "e":
       System.out.println("e");
       break;
      
}
   }
   }

import java.util.Scanner;

public class ATMMain {
   public static void main(String[] args) {
       double Ibalance = 5000, usermoney, withdrawB, depositD;
       String userFname = "X";
       String userLname = "X";
       String w, d, e, c;
       System.out.println("Welcome");
       Scanner input = new Scanner(System.in);
       System.out.println("Welcome" + " " + userFname + " " + userLname);
       System.out.println("your current balance" + " " + Ibalance);
       System.out.println("Enter in w = withdraw, d = deposit, c = check, or e = logout");
       w = input.next();

       if (w.equalsIgnoreCase("w")) {
           System.out.println("How much do you want to withdraw");
           usermoney = input.nextDouble();
           withdrawB = Ibalance - usermoney;
           System.out.println(withdrawB);
       } else if (w.equalsIgnoreCase("d")) {
           System.out.println("How much do you want to deposit");
           usermoney = input.nextDouble();
           depositD = Ibalance + usermoney;
           System.out.println(depositD);
       } else if (w.equalsIgnoreCase("c")) {
           System.out.println(Ibalance);
       } else if (w.equalsIgnoreCase("e")) {
           System.out.println("logging out");
       } else {
           System.out.println("invalid input");
