java programming language 4th edition

Problem Descriptionn individuals in a circle, numbered from 1 to n sequentially. From the person numbered 1 starts 1 to K, where the number of people who count K out of the circle, the output of the last left a person's original numbers.InputFirst enter a T, which indicates that there is a T group of data (1Then there are t-lines, each with 2 positive integers n and K. (1OutputFor each set of test data, output a number that represents the number of the last person left.Sample Input310 37 15 4Sam

general enough, the programmer is not constrained to any particular type of problemElements in the problem space represent as objects in the solution space. (you'll also need other objects, that don ' t has problem-space analogs)　　OOP allows describe the problem in terms of the problem.Each object look quite a bit like a little computer--it have a state, and it had operations that you can ask it to perform.Alan Kay summarized five basic characteristics of Smalltalk, the first successful objecct

between "test" and "123". So the two strings are not equal. Wrong title 5: Understanding: NumberFormat always loops; It never truncates. Moreover, it provides a method of currency and percentage. Wrong title 6: Understanding: Import statements can only be used with one (wildcard). If you also need to import all the secondary levels of a package, you must explicitly write them out:?? ?

)After the actual operation of the code in the book, it is found that not all the code should be written again ... Always after writing a piece of code to read the book found that the code does not make much sense, and the real need to operate the part is still behind, so efficiency is a lot lower. For this week's study I basically spend 80% of my spare time in learning Java is not only reading books and watching videos and surfing the Internet to und

body. This is a traditional way of building a switch statement, but break is optional. If break is omitted, the subsequent case statement (if any) continues to be executed until a break is encountered. Note that the last default statement has no break because the execution process has reached the break's jump destination, and of course, you can completely A break is placed at the end of the statement, although doing so is of no use.

interface 1、接口定义行为： 对于“定义行为”，可以使用interace关键字定义。 类要操作接口，必须使用implements关键字。 操作某接口时，对接口中定义的方法有两种处理方式，一是操作接口中定义的方法，二是再度将该方法表示为 abstract。 2、行为的多态： 只要是操作同一个接口的对象，都可以使用同一方法（行为）。 3、解决需求变化： 在java中，类可以操作两个以上的类，也就是拥有两种以上的行为。 在java中，接口可以继承自另一个接口，也就是继承父接口行为，再在子接口中额外定义行为。7.2 Interface Syntax Details 1、接口的默认： 接口中的方法没有操作时，一定得是公开并且抽象。 2、匿名内部类： 临时继承某个类或操作某个接口并建立实例，由于只使用一次，不需要为这些类定义名称，这时可以用匿名内部 类（Anonymous Inner Class）。 3、使用

not flexible, good maintenance problems; There are some less expressions in the book, Places that are not very well understood, such as the instanceof operator, override, and so on, can only be learned through video.

Problem DescriptionThis day the teacher gave small Hao a very simple topic relaxed: Enter a score, let you find their simplest score. InputThe first line includes a T, which represents the number of groups of test data.The next line of T lines includes a fraction. (The numerator denominator is within the int range)OutputFor each test sample, the output line has its simplest fraction.Sample Input32/63/111/36Sample Output1/33/111/36My Code:1#include 2ProcessintAintb/*greatest common divisor, so th
