Search & Filtering
Advanced Systems (AS) is a big electronics company working with electronics and hardware. They hired you to lead the new established Software Development department. The first thing you tasked to do is to increase the awareness of software development in the company. To do so, the following tasks should be conducted:
Task (1): prepare report that includes:
1. Description the steps of application development process.
2. Explanation of what an algorithm is, with examples of their use, use insertion sort or binary search as an examples.
3. Identify the steps needed to convert the insertion sort algorithm or the binary search algorithm to an executable code. Show snapshots in each step.
One form of Ohm’s law is:
E = I×R
where,
- E is applied voltage and is measured in volts(V)
- I is circuit current and is measured in amperes(A)
- R is circuit resistance and is measured in ohms(Ω)
To find E when I = 5mA and R = 2.7KΩ, first convert 5mA to 5×10-3A, 2.7KΩ to 2.7×103Ω and then perform the following calculation
E = 5×10-3A × 2.7×103Ω = 13.5V.
Create Java program that (a) creates a supporting class name, Ohm, which contains one method named, getOhm, that takes two inputs, I (circuit current) and R (circuit resistance), to return the calculation result of E= I×R, (b) create a class with “main” method in it, (c) the main method takes two double values, I and R, (d) create instance of the Ohm class and use it to call the getOhm method with the two double values (I and R) passing to the getOhm method, (e) display returned calculated value in a message box. Be sure to use ampere (A) and ohm (Ω) as units.
Submarine
Given two numbers
totalTorpedos, torpedosFired as inputs, write a super class Submarine with property and methods as below,PropertyDescription
The sequence of operations is,
- Submerge the Submarine
- Fire torpedos
- Surface the Submarine
Input
- The first line of input contains a number totalTorpedos
- The second line of input contains a number torpedosFired
Output
- The first line of output is a string with Submarine Submerged text
- The second line of output is a string with the number of torpedos fired and left, as shown in sample outputs
- The third line of output is a string with Submarine Surfaced text

Write a program that reads and records magazine sales for 5 students. Record a
student’s name, the magazine sold, and the number sold. Information should be read
in one record at a time – that is to say, read one student, magazine, and number before
getting the next set. (Similar to the example in the notes.) Produce a table that
displays the recorded information.
Note: use multiple arrays
