Today just began to read effective Java, the Chinese version of the reading is very awkward, but feel a lot of harvest.In addition, the content of this book is for Java 1.5 and 1.6.Here's the 2nd Chapter: Creating and destroying the contents of an object.First: Consider replacing the constructor with a static factory m

Before reading this book "Effective Java (second edition)" is very early. This book is indeed a good book. You need to chew slowly and have a different experience every time you look.Write a blog here to consolidate.Chapter I.

Classic sorting Algorithm (Java edition) reprint1. Bubble Sort BubbleThe simplest sort method is the bubble sort method. The basic idea of this approach is to think of the elements to be sorted as "bubbles" that are vertically arranged, smaller elements lighter and thus upward. In the bubble sorting algorithm we have to deal with this "bubble" sequence several times. The so-called process, is to check the s

containing a number that appears only once, and the other numbers appear two times. We already know how to find the only one occurrence in the array, so all the problems are solved in this position.For example, the number added to our input is {2,4,3,6,3,2,5,5}. When we make an XOR operation of each number in the array, the resulting result is represented by a binary representation of 0010. The second-to-last digit in the result of XOR or obtained is 1, so we are 1 divided into two arrays accor

node in a single-linked list, then the single-linked list does not need to be reversed, and if there is only one element in the single-linked list, its position will not change after the reverse, so it can not be reversed. When there are 2 or two or more elements in a single-linked list, it is broken from the 1th element, so that its next is empty, then the 2nd element is accessed to the nth element, and when one of the elements is accessed, it is in

elements in the following insertion sorting algorithm, in order to write a program we can introduce a sentinel element L[0], which is less than any record in L[1..N]. So, we have a constant-∞ in the type ElementType of the element, which is smaller than any record that might occur. If the constant-∞ is not good in advance, it is necessary to check if the current position is 1 before deciding whether L[i] will move forward, and if the current position is 1 o'clock, the processing of the I-pass s

Given an input string, reverse the string word by word.For example,Given s = " the sky is blue ",Return " blue is sky the ".Click to show Clarification.Clarification: what constitutes a word? A sequence of non-space characters constitutes a word. could the input string contain leading or trailing spaces? yes. However, your reversed string should not contain leading or trailing spaces. how about multiple spaces between? reduce them to a single space in the reversed string.

The key is the picture and picture, this is the author most like to see, and sometimes write more, also less than a picture to make it easier to understand, for example, the object instantiation process in this chapter pictures (recommended to study this diagram, enhance stack and heap understanding), the last master to speak very interesting, The content in the interview is often asked.Because just read a chapter, the other co
