Help!!! Applying Discount Code Challenge

Question

I'm new to programming. I'm taking the Java course and I'm stuck with this challenge task 1 of 2.
Issue: Compile error
Target: create a new private method named normalizeDiscountCode. It should take the discount code that is passed into the method and return the uppercase version. Call it from the current applyDiscountCode method and set this.discountCode to the result.
'''
import java.io.*;
String Str = new String();
  private String normalizeDiscountCode (String discountCode){
    this.discountCode = str.toUpperCase(discountCode);
    return discountCode;
  }
  public void applyDiscountCode(String discountCode){
    this.discountCode = normalizeDiscountCode(discountCode);
  }'''
I've followed the instructions on how to use toUpperCase() method on the link (https://www.tutorialspoint.com/java/javastringtouppercase.htm)

Hi there. You don't really need to create a new string variable Str here. You can call the toUpperCase method directly on the string that was passed in and return it that way, without any intermediary. All we need to do is accept the discount code as input to the method and return a version in all caps. Try something like:
```java
private String normalizeDiscountCode(String discountCode) {
return discountCode.toUpperCase();
}
```
