Java英文面试问答(一)

Java is a versatile programming language that is based on C++. It is a general-purpose, object-oriented, class-based, concurrent, and the runtime environment independent of platform. It is one of the popular and most used language that is used in different domains such as banking, retail, information technology, Android, financial services, stock market, Big Data, and scientific and research community. This article on Java interview questions covers basic as well as advanced questions on Java programming.

1. What is Java?
Java is a platform-independent high-level programming language developed by Sun Microsystems. It is used for developing a wide variety of applications. It consists of advanced and simplified features and is free to access. It can execute multiple functions at the same time and is developed on the logic of "Write once, Run anywhere."

2. What are the features of Java?
Java is a highly effective programming language that has created an ocean of opportunities. Some of the most brilliant features of it are:

Simplicity: Java is more preferred than other programming language, including C++ because it removed all the complexities like pointers, and operator overloading.
Portable: Being platform-independent, Java has made easy to port any application from one platform to another.

Object-oriented: Java considers everything as an object where it stores different properties, behavior, and features of different categories. These objects are used to perform entire operations.

Secured: Java compiles and converts all the code into bytecode, which is understood only computers that run it. By removing explicit pointer and running programs inside the sandbox, Java has made tampering with applications from untrusted sources impossible. With Java, developers can develop applications free of virus and robust systems/applications.

Dynamic: Java has enabled the reduction of memory wastage and enhancing the performance of the application with its ability to adapt to an evolving environment and support dynamic memory allocation.
Multithreaded: Java makes programming with threads easier by supporting lightweight processes or multiple threads execution.

自从我室友在计算机导论课上听说了“刷 LeetCode 是进入大厂的敲门砖”,整个人就跟走火入魔了一样。他在宿舍门口贴了一张A4纸,上面写着:“正在 DP,请勿打扰,否则 Time Limit Exceeded。”日记本的扉页被他用黑色水笔加粗描了三遍:“Talk is cheap. Show me the code。”连宿舍聚餐,他都要给我们讲解:“今天的座位安排可以用回溯算法解决,但为了避免栈溢出,我建议用动态规划。来,这是状态转移方程:dp[i][j] 代表第 i 个人坐在第 j 个位置的最优解。”我让他去楼下取个快递,他不直接去,非要在门口踱步,嘴里念念有词:“这是一个图的遍历问题。从宿舍楼(root)到驿站(target node),我应该用 BFS 还是 DFS?嗯,求最短路径,还是广度优先好。”和同学约好出去开黑,他会提前发消息:“集合点 (x, y),我们俩的路径有 k 个交点,为了最小化时间复杂度,应该在 (x/2, y/2) 处汇合。”有一次另一个室友低血糖犯了,让他帮忙找颗糖,他居然冷静地分析道:“别急,这是一个查找问题。零食箱是无序数组,暴力查找是 O(n)。如果按甜度排序,我就可以用二分查找,时间复杂度降到 O(log n)。”他做卫生也要讲究算法效率:“拖地是典型的岛屿问题,要先把连通的污渍区块都清理掉。倒垃圾可以用双指针法,一个指针从左往右,一个从右往左,能最快匹配垃圾分类。”现在我们宿舍的画风已经完全变了,大家不聊游戏和妹子,对话都是这样的:“你 Two Sum 刷了几遍了?”“别提了,昨天遇到一道 Hard 题,我连暴力解都想不出来,最后只能看题解。你呢?”“我动态规划还不行,总是找不到最优子结构。今天那道接雨水给我整麻了。”……LeetCode 真的害了我室友!!!
