Should Java specifications read?

The general answer is: Yes it is worth. If you want to write portable code, it is mandatory. For some languages, it is just unavoidable, e.g., Ada or perl. Moreover, if you don’t only write code but also read code from others, you’ll eventually have to refer to the specification.

Should I bother learning Java?

Learning Java Is a No-Brainer But, if you’re looking to learn how to code and are not sure about which language to learn, Java is certainly worth mulling over.

Should I learn Java as a beginner?

How many hours should I study Java?

What is a class in Java?

The picture above shows a small Java class and a description of how the initialization of that class could be done in reality. There is no concept of classes in a native language, which means the program needs to be expressed by instructions, one after another.

What is the use of serialversionuid in Java?

During serialization, Java runtime creates a version number for a class, so that it can de-serialize it later. This version number is known as SerialVersionUID in Java. SerialVersionUID is used to version serialized data. You can only de-serialize a class if it’s SerialVersionUID matches with the serialized instance.

Are all primitive types serializable in Java?

All primitive types are serializable. Transient fields (with transient modifier) are NOT serialized, (i.e., not saved or restored). A class that implements Serializable must mark transient fields of classes that do not support serialization (e.g., a file stream).
