Comparing Strings in Java | Baeldung
June 19, 2024 - >> Flexible Pub/Sub Messaging With Spring Boot and Dapr · In this article, we’ll talk about the different ways of comparing Strings in Java. As String is one of the most used data types in Java, this is naturally a very commonly used operation. Using the “==” operator for comparing text values is one of the most common mistakes Java beginners make. This is incorrect because “==” only checks the referential equality of two Strings, meaning if they reference the same object or not.

You can try "Query creation from method names".
Let's say you want to search Orders by orderstatus <> submitted,
List<Order> findByOrderstatusNot(String orderstatus);

Have you taken a look at the documentation about this in the Spring Data JPA docs?
#findByStatusCodeNot(String statusCode);
It's akin the example in the docs like:
#findByLastnameNot

According to the Spring Data JPA Documentation on https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#reference
you can achieve this by using the Not keyword. For instance your method would become
findByStatusCodeNot(String statusCode);
This means to achieve statusCode != 'Denied', you would call the method as
findByStatusCodeNot('Denied');

How do I compare values in Spring EL? - Learn Java by Examples
For these kinds of comparison, below are the list of operators supported by Spring EL, as expected it supports the same operators as in the Java programming language. The Spring Expression Language comparison operators includes: For example, you can use the double-equal operator like the following XML configuration: <property name="empty" value="#{myGlass.volume == 0}"/> It means that we are going to set the empty property to be either a boolean true or false if the value of myGlass.volume is equal to 0 or not.

August 16, 2022 - With the equals() method, we got true because it only checks if values inside the String objects are the same. The Objects.equals() is a null safe method. If both parameters are null, true will be returned. If the first argument is not null, equality is determined by calling its equals() method with the second argument provided. Otherwise, false will be returned. import java.util.Objects; public class Test { public static void main(String[] args) { String str1 = "java"; String str2 = new String("java"); System.out.println(Objects.equals(str1, str2)); System.out.println(Objects.equals(null, str1)); System.out.println(Objects.equals(null, null)); } }

If you wanted str1 and str2 to refer to separate instances then you need to use the "new" keyword. String str1 = new String( "hello"); String str2 = new String(str1); str1==str2 // false with objects use == to compare references and str.equals() to compare there values

Why strings are not equal? (Beginning Java forum at Coderanch)
My guess is that the replace() method is optimized so that if you replace 'g' with 'g', it knows there is no point in doing so. It saves the overhead of building a new object. And since you are using a string literal, and the same string literal, in both places, they are both in the String pool, and thus are still equal.
