Program Plan Intro
ObjectInputStream/ObjectOuputStream:
The “ObjectInputStream/ObjectOuputStream” classes are used to read/ write serializable objects. It is used to perform I/O for objects in additions to primitive-type values and strings, “DataInputStream/DataOutputStream” can be replaced with the “ObjectInputStream / ObjectOuputStream”.

This is for Java. Please help. Thanks
True or False?
Instantiating an array of objects reserves room to store references only.
1. The append() method concatenates the string representation of any other type of data tothe end of the invoking StringBuffer object. It has several overloaded versions. Here are afew of its forms:StringBuffer append(String str)StringBuffer append(int num)StringBuffer append(Object obj)2. The result is appended to the current StringBuffer object.3. The buffer itself is returned by each version of append( ).4. This allows subsequent calls to be chained together, write java code for it

- Take a close look at the C++ code in IntCollection.zip (Copy and Paste link to the external site http://fog.ccsf.edu/~mluttrel/cs110b/IntCollection.zip ) on my web site. The IntCollection class is a dynamic storage mechanism for storing integers. It could be used in place of an integer array. The following code creates an IntCollection object named ‘c’. It adds seven integers to ‘c’, then uses a for loop to display the seven integers: int main(){IntCollection c;c.add(45);c.add(-210);c.add(77);c.add(2);c.add(-21);c.add(42);c.add(7);for (int i = 0; i < c.getSize(); i++){ cout << c.get(i) << endl;}} For this assignment you will add a copy constructor, a destructor, and three overloaded operators to the IntCollection class. In the design diagram below, the black member functions represent code that has already been implemented. You will be implementing the green items. Each item that you will be adding to the class is described below the diagram. private:…arrow_forward1.

- The goal for Lab06a is to use the provided Student class and create an array of Student objects that are stored in a School object. This program uses a Student class that is provided See the work area. The class is placed in its own separate file and should not be altered. The Lab06avst.java file is also provided for you in the work area. You will not see the Student class here. There is evidence that the Student class is used, as you see in line 17, but the class is separate in its own file, which is better Object Oriented Design. Specifics and Output 10 Student objects need to be constructed and placed in a students array, which is stored in a School object. The actual data used in the Student objects can be seen by the output below. This program requires the completion of the School constructor. It also requires the completion of the addData method.

This program uses a Student class that is provided(picture attached!). The class is placed in its own separate file and should not be altered. This project started with Lab06a and uses the same Student class. Part one of Lab07 is similar to the Lab06b.
