got error "incompatible types: void cannot be converted to int" in OOP

I'm pretty new to Java and stackoverflow so sorry for any confusions. Below is my code and I got the following errors:

./LETest.java:8: error: incompatible types: void cannot be converted to int
int returned = savingsTest.withdraw(200);
^
./LETest.java:18: error: incompatible types: void cannot be converted to int
int returned = savingsTest.withdraw(500);
^
2 errors

The IDE did print out the following results though:

Hello!
Your balance is
You just deposited 500
You just withdrew 200

Code:

public class SavingsAccount {
  
  int balance;
  int amountToDeposit;
  int amountToWithdraw;
  
  // initial balance
  public SavingsAccount(int initialBalance){
    balance = initialBalance;
  }

  // check balance
  public void checkBalance(){
    System.out.println("Hello!");
    System.out.println("Your balance is " + balance);
  }
  
  // deposit
  public void deposit(int amountToDeposit){
    balance = balance + amountToDeposit;
    System.out.println("You just deposited " + amountToDeposit);
  }

  // withdraw
  public void withdraw(int amountToWithdraw){
    balance = balance - amountToWithdraw;
    System.out.println("You just withdrew " + amountToWithdraw);
  }

  public static void main(String[] args){
    SavingsAccount savings = new SavingsAccount(2000);

    savings.checkBalance();
    savings.deposit(500);
    savings.withdraw(200);

  }       
}

Would someone mind helping?

I tried changing void to int in the withdraw() method and got a new error

SavingsAccount.java:30: error: missing return statement
  }
  ^
1 error

You know you want to change the return type of withdraw to int. And you know you were missing a return. Presumably you want to return the newBalance. So add that. Like,

// Withdraw. Take an int. Return an int.
public int withdraw(int amountToWithdraw) {
    int newBalance = balance - amountToWithdraw;
    balance = newBalance;
    System.out.println("You just withdrew " + amountToWithdraw);
    return newBalance; // The int to return.
}

Your code is slightly different than what is reported in the error.

./LETest.java:8: error: incompatible types: void cannot be converted to int
int returned = savingsTest.withdraw(200);
^
./LETest.java:18: error: incompatible types: void cannot be converted to int
int returned = savingsTest.withdraw(500);
^
2 errors

These errors are reporting from lines 8 and 18.

int returned = savingsTest.withdraw(200);
int returned = savingsTest.withdraw(500);

Which, is not in the code you provided.

Nevertheless, I'll explain the situation you encountered.

In Java, a method is declared with a return type.
If you don't intend on returning a value, you can use void.
Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects).

The error you're encountering is because you're attempting to assign a void to an int.
The withdraw method is declared as void.

You mention the following.

> "I tried changing void to int in the withdraw() method and got a new error"

The error encountered here is because, if a method is declared with a return type, you must use the return keyword, and the value.
Returning a Value from a Method (The Java™ Tutorials > Learning the Java Language > Classes and Objects).

For example, if you wanted to return a value from the withdraw method, you could use the following.

public int withdraw(int amountToWithdraw){
    balance = balance - amountToWithdraw;
    System.out.println("You just withdrew " + amountToWithdraw);
    return balance;
}

Additionally, the correct accounting term would be, withdrawal.
