If it stores any type of objects mixed, use Object as storage class. All classes inherit from Object and for primitives use their respective wrapper classes. Or just use one of the bazillion container classes that already exist.
The option which is not correct concerning database design is identify all fields needed to produce the required information.
What is database design?
The database design is the arrangement of the data or the information, according to the model of database.
Let's check all the option one by one,
- Identify all fields needed to produce the required information- This does not concern with the database design.
- Group related fields into tables-A relation database design consist of one or more than one related table. These tables are used together when the information is required.
- Determine each table's primary key- To determine the table's primary key, is the concern with the database design.
- Organize each piece of data into its largest useful part-The database design is the organization of data in the model of database.
The option which is not correct concerning database design is identify all fields needed to produce the required information.

The decimal form of the 11001101.00111001.10101001.01000010 binary ip address is 205.57.169.66.
An IP address is a binary number with 32 bits. The 32 bits are divided into four octets, which are groupings of 8 bits each. An IP address, however, is shown as a dotted decimal number (for example: 205.57. 32.9).
Memory regions are given binary addresses by the computer system. But in order to access a memory location, the system utilises a certain number of bits. We can address two memory regions with 1 bit. We can address 4 memory locations with 2 bits and 8 memory locations with 3 bits.
The 4 sets of 8 bits in each of the 4 directions are simply written down to create the 32-bit binary IP address.

Answer:
All of the files are stored on a hard-drive. Except for the files you just viewed before turning off the computer, which is stored in the RAM (Random Access Memory). If your computer is a desktop, and the power goes out while looking at a photo/pdf, you may corrupt/lose the image if the computer didn't have enough time to store it in the hard drive. Everything in the hard drive is 'scratched' into it like a record. If you delete a file, that part of the disk is 'smoothed' as best as it can. If you upload another file, you might corrupt/ruin the image/pdf. Think of the smoothing like recording a football game over an old VHS of Winne the Pooh.

Answer:
b) public static double calcShippingCost(double weight) { double cost; if(weight < 10) { cost = 10.0; }else{ cost = 15.5; } cost = cost + calcTax(cost); return cost; }
The method is called twice with arguments 7.5 and 17.5 respectively.
Explanation:
The Java program defines three user methods including the main. In the main, the calShippingCost method is called twice with 7.5 and 17.5 respectively to return double number values to cost1 and cost2.
