ArrayList vs Array: While both can store elements, ArrayList is resizable and provides built-in methods for element manipulation. Arrays are fixed-size and don’t have these built-in methods. However, arrays can be more efficient in terms of memory and access speed, especially for a large num...

The JarInputStream class now treats a signed JAR as unsigned if it detects a second manifest within the first two entries in the JAR file. A warning message "WARNING: Multiple MANIFEST.MF found. Treat JAR file as unsigned." is logged if the system property, -Djava.security.debug=jar, is...
Instances of the class Class represent classes and interfaces in a running Java application. An enum type is a kind of class and an annotation type is a kind of interface. Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same...
