Programming | Repeating Java has a lot of praise of the function, the application of code is one of them. But if you want revolutionary change, you have to go far beyond the old code of "Replicator code, then change": combination (composition) and inheritance ( Inheritance) ToString (): Objects of each non-basic class have ToString (), which is called when the compiler expects a string and you have only those objects in your hand. Test tips: "Provid

The importance of the data structure to the program is self-evident, in the Java language to achieve a number of common structures, as well as the corresponding data structure on the learning of Java students must be mastered.This series of posts refer to the data structure and problem solving-java Language Description (third edition) to achieveIn their own learn

https://oj.leetcode.com/problems/plus-one/Test instructions: An integer is stored in an int array in the order of the highest bit in array[0], the lowest bit in [n-1], for example: 98, stored as: array[0]=9; array[1]=8;The idea of solving problems, starting with the last digit of the array and adding 1, you need to consider rounding, if there is still a carry after the [0] bit, you need to open an array of length (N.length + 1) and copy the original a

Problem Description: 0-1 Backpack: There are n items and a backpack with a weight of M. (Each item is only one) the weight of item I is w[i], value is p[i]. Solving which items are loaded into the backpack can make the sum of the greatest value. Dynamic planning: Dynamic programming algorithms are often used to solve problems with some of the best properties. Th
