Warehouse Inventories Objective: Work with multiple objects and review reading data files. Description: A wholesale distributor has six warehouses (Atlanta, Baltimore, Chicago, Denver, Ely and Fargo) and sells five different items (identified by part number: 102, 215, 410, 525 and 711). Each warehouse may stock any or all of the five items. The company buys and sells these items constantly. Company transaction records contain a transaction code (‘P’ for a purchase or ‘S’ for a sale) followed by an item number and the quantity (bought or sold). The transaction records are contained in a transaction data file named Transactions.txt. Sample transaction records: Transactions.txt P 410 1000 S 215 120 S 711 300 | A separate data file contains the initial status of the six warehouses at the beginning of the day (i.e., the ending status from the night before). This data file has only six records (lines). Each record (line) contains five numbers that show the quantity on hand for the five items in that warehouse. This file is named Inventory.txt. Sample status data file: Inventory.txt 500 120 60 0 350 100 230 0 50 0 0 75 0 0 220 600 50 120 300 40 210 160 30 80 50 90 50 90 200 70 | The status data file is updated by processing the transaction records in the transaction data file according to these rules: 1 – For a sale (‘S’) – subtract the quantity sold from the warehouse that has the largest supply of that item on hand. 2 – For a purchase (‘P’) – add the quantity purchased to the warehouse that has the lowest supply of that item on hand. Instructions: Write an object-oriented Java program to do the above inventory warehouse processing. Each of the six warehouses should be treated as an individual object. For example, Atlanta would be an object with each of the five part numbers as instance fields. Each of the other warehouses should also be objects with the five part numbers as instance fields. Of course, there would be one class which would be the main (driver) class from which these 6 objects would be created. In the beginning of the program, the status data file (Inventory.txt) should be read and an object for each warehouse created. The Inventory.txt data file is in the following order: the first line is the Atlanta warehouse, the second line is the Baltimore warehouse, third Chicago, then Denver, Ely and Fargo. After the objects are created, the transactions data file (Transactions.txt) are read and processed. The objects should be updated as the transaction records are read and processed. The program should: 1 – Display the initial (beginning-of-day) status for all warehouses. 2 – Process each transaction from the transaction data file and show which warehouse’s inventory was updated to reflect that transaction. 3 – Display the final (end-of-day) status for all warehouses. Requirements: The class must be named Inventory. The main program (driver) must be named Warehouses. A driver (main class) as well as a programmer-defined class must be used. .

Walt Disney Company is famed for its creativity, strong global brand, and uncanny ability to take service and experience businesses to higherlevels. In the early 1990s, then-CEO Michael Eisner looked to the fast-food industry as a way to draw additional attention to the Disneypresence outside of its theme parks Solution A. Disney is creating value in its business basically by Cost Leadership, the reason being Disney had already mastered high volume food production due to which it could get economies of scale and hence manufacture the products at the lowest cost as compared to its competitors. Also, owing to its reputation in the theme parks, it was charging high prices and still earning profits. Differentiation strategy is one where the business focuses on differentiated product to create value to the customer based on which it earns profit. Here as explained in the text, Disney is not all earning profits due to any kind of differentiated products in their markets. B. The first and the foremost thing which Mickey.

Voter attitudes - Suggest properties of voter attitudes that can be measured by each of the four basic levels of measurement (nominal, ordinal, interval and ratio) please explain how voter attutitudes can be measured by nominal,ordinal,interval and ratio scales..... Solution 1) In all regions, compared with the young (those under 30 years old), the elderly (those over 65 years old) are more authoritarian and more likely to vote for right - wing parties. A significant body of research shows political attitudes to be more resistance to change as people age (Alwin and Kosnick, 1991; Glenn, 1980; Jennings and Markus, 1984; Markus, 1979), with people be coming more socially conservative (see, for example, Park, 2000). In none of the regions we examined is there a party that uniquely represents the old, but the party structures are all similar in that there are distinct right-wing (socially conservative) parties with similar authoritarian platforms. We expect, then, that these authoritarian attitudes will be reflected in a greater propensity for seniors to vote for right-wing parties. 2) In all regions, compared to whites, visible racial minorities are more left in terms of attitudes and vote. The basis for this hypothesis is that ethnic minorities are more likely to be discriminated against in the job market and elsewhere than others. It follows that left-leaning policies, such as laws ensuring equal opportunity and income redistribution, are in the interest of racial minorities. Since it is rational to want to improve one.

Violent vs. Non-violent solutions. Violent solutions are temporary solutions. Nonviolent solutions are more permanent due to the fact that the process for achieving the solution is consistent with the goal. It was said by Napoleon that everything taken by force is temporary. Nonviolence is more permanent because it is based on social growth, human reconciliation, and changing conditions. With respect to this statement, how would you apply it to the conflict found in the Middle East? Solution The conflict in the Middle East is an altogether different scenario. Its a conflict between the two Islamic sects, that has been there since almost a millennia. Historically, the Shia\'a sect is recognised as more \'Persian\' since Iran itself is a predominantly Shiite nation. When the caliphate invaded Persian lands, its people recognized themselves as a different sect since they were non-Arabs and supported Muhammad\'s son-in-law and cousin Ali Talib to be the successor of the caliphate. Since he was killed in battle by the armies who supported Abu Bakr as the rightful successor, Sunni Islam became the dominant sect - roughly 90% of the Muslim population is Sunni. Now, in such cases non-violence cannot really be used since its a conflict that also involves terrorism. Since terrorism itself is an armed movement, stopping it requires force. Non-violence is used more in socio-political situations - the movements in South Africa, independence movement in India are some historical examples where the objective was to achieve a socio- political aim. For example, the laws of British imperialism were the cause of unrest in India that led to non-violent movements to achieve constitutional sovereignty. It was a socio-political objective led with a motive to achieve long term goals like stability & economic growth. Of course, a lot of violence was involved, but the ultimate objective could be met with only organised protest. Armed conflicts are achievable only when one faction or a party is able to assimilate annexed territory and people. This was not the case with Napoleon and with so many other dictators. Assimilation, establishing administration, peace and rule of law takes a lot of time. It involves establishing a welfare state for everyone affected. Besides, there always has to be a casus belli behind every armed movement. The reason why Napoleon failed is because his conquests were seen as forceful and lacking a justification - people outside the French borders were never ready to accept his rule. Similar is the situation in the Middle East. Since the Americans left, they appointed a Shiite President to head the country. The Sunnis never really liked this stance and add to it some of the pro-Shiite stance taken by the Iraqi president, was enough to further deepen sectarian tensions. So, non-violent movements require an environment where they can be executed. When an armed conflict is underway, there is little space for non-violence..

Very recently, the GBP has been raising against the Euro. I understand this has to do with the EU injecting Solution What bdsl\'s comment means is this: Suppose there was a way for \"experts\" (here or anywhere else) to predict when the pound would start depreciating against the euro, and that this method predicted that it would begin to do so tomorrow. What would the experts do with this information? They would start selling pounds today in order to get out of the market at the top. But this rush of selling activity would cause the value of the pound to fall (via the usual principle of supply and demand) today.
