Can you explain what it means to specify time in UTC format?

The final keyword in Java is a modifier that can be applied to classes, methods, and variables.

• For a class: it cannot be subclassed.
• For a method: it cannot be overridden.
• For a variable: its value cannot be changed after initialization.

The finalize() method is a method defined in the Object class and can be overridden to release resources before the object is garbage collected. However, its use is discouraged because calling finalize() is not guaranteed and can lead to unpredictable behavior.

Example of using final:

final class Constants {
    public static final double PI = 3.14159;
}

class MyClass {
    public final void doSomething() {
        // this method cannot be overridden
    }
}

The finalize() method looks like:

@Override
protected void finalize() throws Throwable {
    try {
        // resource cleanup
    } finally {
        super.finalize();
    }
}

But it is better to use other resource management mechanisms, such as try-with-resources.
