The talk-a-lot cell phone company provides phone services for its customers. create an abstract class named phonecall that includes a string field for a phone number and a double field for the price of the call. also include a constructor that requires a phone number parameter and that sets the price to 0.0. include a set method for the price. also include three abstract get methods—one that returns the phone number, another that returns the price of the call, and a third that displays information about the call. create two child classes of phonecall: incomingphonecall and outgoingphonecall. the incomingphonecall constructor passes its phone number parameter to its parent’s constructor and sets the price of the call to 0.02. the method that displays the phone call information displays the phone number, the rate, and the price of the call (which is the same as the rate). the outgoingphonecall class includes an additional field that holds the time of the call in minutes. the constructor requires both a phone number and the time. the price is 0.04 per minute, and the display method shows the details of the call, including the phone number, the rate per minute, the number of minutes, and the total price. write an application that demonstrates you can instantiate and display both incomingphonecall and outgoingphonecall objects. save the files as phonecall. java, incomingphonecall. java, outgoingphonecall. java, and demophonecalls. java.

Read this excerpt from helen keller’s autobiography, the story of my life. have you ever been at sea in a dense fog, when it seemed as if a tangible white darkness shut you in, and the great ship, tense and anxious, groped her way toward the shore with plummet and sounding-line, and you waited with beating heart for something to happen? i was like that ship before my education began, only i was without compass or sounding-line, and had no way of knowing how near the harbour was. "light! give me light! " was the wordless cry of my soul, and the light of love shone on me in that very hour. . the morning after my teacher came she led me into her room and gave me a doll. the little blind children at the perkins institution had sent it and laura bridgman had dressed it; but i did not know this until afterward. when i had played with it a little while, miss sullivan slowly spelled into my hand the word "d-o-l-l." i was at once interested in this finger play and tried to imitate it. when i finally succeeded in making the letters correctly i was flushed with childish pleasure and pride. running downstairs to my mother i held up my hand and made the letters for doll. i did not know that i was spelling a word or even that words existed; i was simply making my fingers go in monkey-like imitation. in the days that followed i learned to spell in this uncomprehending way a great many words, among them pin, hat, cup and a few verbs like sit, stand and walk. based on this excerpt, which words best describe helen keller?
