Question
How can I obtain the current class name in Java without unwanted suffixes or characters?
String className = this.getClass().getName();
Answer
In Java, when retrieving the class name using `this.getClass().getName()`, it returns the fully qualified name of the class, which may include additional suffixes. This is particularly common when working with inner classes or anonymous classes, which can produce names that look like `OuterClass$1`. To obtain just the simple class name without any unnecessary characters, a different method can be used.
String className = this.getClass().getSimpleName();
Causes
- Using `getName()` returns the fully qualified name including the package and any inner class indicators.
- Inner classes and anonymous classes automatically get a suffix (like $1) which is part of their naming convention.
Solutions
- Use `getSimpleName()` method to retrieve only the class name without package or inner class indicators.
- Alternatively, split the result from `getName()` to isolate the name component.
Common Mistakes
Mistake: Continuing to use `getName()` when you only need the class name.
Solution: Switch to `getSimpleName()` for a cleaner output.
Mistake: Assuming inner classes return the same name as outer classes.
Solution: Understand how inner class naming works in Java.
Helpers
- Java get current class name
- Java getSimpleName()
- Java class name without suffix
- Java getClass() method
- Java retrieve class name
