2019S CS102A Assignment 2A2Q1: Chinese Lunar year[20 points]Please write a program to show the Chinese Lunar year of Stems-and-Branches(天干地支) according to the year number, and the animal symbol(属相) of the year which a person was born in. The Stems-and-Branches uses 10 Stems called:jia, yi, bing, ding, wu, ji, geng, xin, ren, and gui(甲乙丙丁戊己庚辛壬癸), and 12 Branches called zi, chou, yin, mao, chen, si, wu, wei, shen, you, xu and hai(子丑寅卯辰巳午未申酉戌亥).Combining each of the10 Stems with one of the 12 Branches in sequence creates 60 chronological symbols.For example jiazi, yichou, bingyin, etc. These 60 symbols are used in circles and thus each year has a chronological symbol. And the Branches also represents the animal symbol of Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, Pig. For example, it is the year of JiHai(己亥年) in 2019. And it is the year of Pig.Search on web how to calculate it. And write a program using switch statement.Tips:(1)Remainder=Year%10, {(Stems:remainder) }={(jia:4)}{(yi:5)}(bing:6)(ding:7)(wu:8)(ji:9)(geng:0)(xin:1)(ren:2)(gui:3)(2)Remainder=Year%12{(Branches:remainder) }={(zi:4)}{(chou:5)}{(yin:6)}{(mao:7)}{(chen:8)}{(si:9)}{(wu:10)}{(wei:11)}{(shen:0)}{(you:1)}{(xu:2)}{(hai:3)}(3)Branches and animal pair{(zi:Rat)}{(chou:Ox)}{(yin:Tigger)}{(mao:Rabbit)}{(chen:Dragon)}{(si:Snake)}{(wu:Horse)}{(wei:Sheep)}{(shen:Monkey)}{(you:Rooster)}{(xu:Dog)}{(hai:Pig)}ref: http://baijiahao.baidu.com/s?id=1543800345816500Sample output:Sample code:public class A2Q1 { public static void main(String[] args){ int year = Integer.parseInt(args[0]); //define the array of Stems-and-Branches, animal symbols String stem[] = ; String branch[] = ; String animal[] = ; // to calculate // output System.out.printf(%s is the year of %s-%s. Also %s year.,...); }}A2Q2: Simple Statistic of number sequence [30 points]Write a program to calculate the average(平均数), mode(众数) and median(中位数) of a sequence of numbers. The average of the numbers is the sum divided by count. The mode is the number appears most frequently. There may be more than 1 mode in a number sequence. The median is the number at “Middle” position of the sequence after sorting. The median is at the “Middle” position of (n-1)/2+1 when n is odd, or is the average value of numbers at position of n/2 and n/2+1.Using Array and for statement.(1)Calculate the average;(2)Count the numbers and find the number appears max times;(3)Sort all numbers from small to big, and find the “Middle”;Tips: args.length shows how many parameters inputted.Sample output:Sample code: public class A2Q2 { public static void main(String[] args){ double number[]; double average = 0.0; double mode = 0.0; double median = 0.0; number = new double[args.length]; //1. to get the input numbers and store in array for (int i=0; i } //2. average double sum=0.0; System.out.printf(average = %.2f ,average); //3. count numbers int count[] = new int[args.length]; for (int i=0; i count[i]=1; } for (int i=0; i } int maxCount=0; //3.1 find the max count for (int i=0; i } //3.2 find the mode with max count System.out.print(mode = ); //4.1 sorting for (int i=0; i for (int j=0; j } } // 4.2 median System.out.printf( median = %.2f,median); }}A2Q3: Grading system [20 points]Please write 2 programs to calculate the GPA at SUSTech:(1)A2Q3_1:Input a score of letter grading, and to calculate the Grade Point. Tips: string.CharAt(int index) returns the value of the character at the specified index of the string(2)A2Q3_2:Input a serials of percentage grading and credit hour, and to calculate the GPA.Sample output：Sample code：public class A2Q3_2 { public static void main(String[] args){ double score[]; int credit[]; if (0==args.length || 0 != args.length%2){ System.out.println(Please input the right format of score and credit hour in pair, eg. 95 2 88 3); return; } score = new double[args.length/2]; credit = new int[args.length/2]; // to get the input numbers and store in array for (int i=0; i } // calculate GP double GP[] = new double[args.length/2]; for (int i=0; i } double GPA=0.0; System.out.printf(GPA = %.2f,GPA); }}Question 4: Calculate [30 points]Write a program using basic arrays to calculate the value of an arithmetic expression consisting of numbers( could be floating-point) and operators +,-,*and / . The arithmetic expression is passed to the program from the command line as a string.Tips:(1)We can assume that the input string always represents a valid arithmetic expression;(2)Only 3 numbers and 2 operators;maybe with a pair of bracket;Sample output:Sample code:public class A2Q4 { public static void main(String[] args) { //if (0 == args.length) return; int n = args[0].length(); double num[] = new double[3];// char cal[] = new char[2];// int nums = 0; int cals = 0; String strNumber = ; //to parse the string for (int i = 0; i //System.out.print(args[0].charAt(i)); switch (args[0].charAt(i)) { case +: // to do youself break; case -: // to do youself break; case *: // to do youself break; case /: // to do youself break; default: // to do youself break; } //System.out.print(nums+,+cals); } // to calculate double result = 0.0; if ((+ == cal[0] || - == cal[0]) && (* == cal[1] || / == cal[1])){ // to finish } else { // to finish } // to print result System.out.printf(%s=%.2f, args[0], result); }}Rules1.Please submit “.java” file of these five questions.2.The class name of each “.java” file should be A2Q1, A2Q2, A2Q3_1,A2Q3_2 , A2Q4 respectively to represent these five questions. 3.No Chinese characters are allowed to appear in your code.4.No package included.5.The arguments and the output must strictly follow the description of each question.6.Please submit your assignment on the SAKAI site of your lab section. Marks will be deducted if you submit later than the deadline. If you submit your assignment within 24 hours after the deadline (grace period), your score will be half of the score you could get if the submission was made before the deadline. Assignments submitted after the grace period will not be graded (meaning you will get a zero for the assignment). 本团队核心人员组成主要包括硅谷工程师、BAT一线工程师，精通德英语！我们主要业务范围是代做编程大作业、课程设计等等。我们的方向领域：window编程 数值算法 AI人工智能 金融统计 计量分析 大数据 网络编程 WEB编程 通讯编程 游戏编程多媒体linux 外挂编程 程序API图像处理 嵌入式/单片机 数据库编程 控制台 进程与线程 网络安全 汇编语言 硬件编程 软件设计 工程标准规等。其中代写编程、代写程序、代写留学生程序作业语言或工具包括但不限于以下范围:C/C++/C#代写Java代写IT代写Python代写辅导编程作业Matlab代写Haskell代写Processing代写Linux环境搭建Rust代写Data Structure Assginment 数据结构代写MIPS代写Machine Learning 作业 代写Oracle/SQL/PostgreSQL/Pig 数据库代写/代做/辅导Web开发、网站开发、网站作业ASP.NET网站开发Finance Insurace Statistics统计、回归、迭代Prolog代写Computer Computational method代做因为专业，所以值得信赖。如有需要，请加QQ：99515681 或邮箱：[email protected] 微信：codehelp
