Best answer: What is SER file in Java?

What is a SER file? SER files mostly belong to Java Development Kit by Oracle. SER files are mainly used to store serialized objects of a Java program.

To serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object is serializable if its class or any of its superclasses implements either the java. io. Serializable interface or its subinterface, java.
