Partner Exercise: Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km – pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a method drive that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank. Also supply methods getGasInTank(), returning the current amount of gasoline in the fuel tank, and addGas(), to add gasoline to the fuel tank. Sample usage: Car myHybrid = new Car(50); // 50 miles per gallon myHybrid. addGas(20); // Tank 20 gallons myHybrid. drive(100); // Drive 100 miles double gasLeft = myHybrid. getGasInTank(); // Get gas remaining in tank You may assume that the drive method is never called with a distance that consumes more than the available gas. Supply a CarTester class that tests all methods.

My favorite is "be concise."have you ever received an email and had to read a page full of information? by the time you finished reading it, you had to re-read it? i have even hit "reply" so that i could break it down into separate paragraphs and send it back to myself.what is concise? get to the point, fast. when opening an email like this, some will close it or print it to read later.i learned to use the subject line to prepare the reader for content. such as, "need on (blank), " "info only re: (blank)," "request input on (blank)," "read before (blank) meeting." these are just some.if you are asking for something, make that your first sentence. follow this by who, what, when, where, and how. use these, as necessary. example; (1) who (who needs it and or who does it), (2) what (specific description of what is needed), (3) when (specific, i need this by 8: 00 am monday or i need this by 10: 00 am today), (4) where (does it have to be printed and taken to someone, maybe the place of the meeting), (5) how (i need it scanned or faxed back to me at this email address, provide me with a hard copy).do not send yet. re-read it. did some spell check change a word? maybe let someone else read it for understanding. you want to avoid multiple emails asking for clarification. if important, put a read receipt on it. you will know it was opened, not necessarily read.end with a you.

Iwould go with b. and plz give me brainliest
