Q1: 一道Java编程题目，新手求详细代码
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class _1 {
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
String zifuchuan = new String("");
int hanzishu = 0;
int zimu = 0;
int kongge = 0;
int shuzi = 0;
int qita = 0;
System.out.print("请输入一行字符：");
BufferedReader stdin = new BufferedReader(new InputStreamReader(
System.in));
zifuchuan = stdin.readLine();
byte[] bytes = zifuchuan.getBytes();
for (int i = 0; i bytes.length; i++) {
if ((bytes[i] = 65 bytes[i] = 90)
|| (bytes[i] = 97 bytes[i] = 122))
zimu++;
else if (bytes[i] == 32)
kongge++;
else if (bytes[i] = 48 bytes[i] = 57)
shuzi++;
else if (bytes[i] 0)
hanzishu++;
else
qita++;
}
System.out.println("字符串所占字节个数为：" + bytes.length);
System.out.println("汉字个数为：" + hanzishu / 2);
System.out.println("英文字母个数为：" + zimu);
System.out.println("空格个数为：" + kongge);
System.out.println("数字个数为：" + shuzi);
System.out.println("其他字符个数为：" + qita);
}

Q2: 请求大神帮我解答这道java编程题（填写代码）
此题的Employee类设计有缺陷，缺少员工薪水的属性。根据题意只能写出下面的程序：
abstract class Employee {
public abstract double earnings();
}
class YearWorker extends Employee {
@Override
public double earnings() {
return 0;
}
}
class MonthWorker extends Employee {
@Override
public double earnings() {
return 0;
}
}
class WeekWorker extends Employee {
@Override
public double earnings() {
return 0;
}
}
class Company {
Employee[] employee;
double salaries = 0;
Company(Employee[] employee) {
this.employee = employee;
}
public double salariesPay() {
salaries = 0;
//计算salaries
for(int i=0; iemployee.length; i++) {
salaries += employee[i].earnings();
}
return salaries;
}
}
public class HardWork {
public static void main(String[] args) {
Employee[] employee = new Employee[20];
for(int i=0; iemployee.length; i++) {
if(i % 3 == 0) {
employee[i] = new YearWorker();
}
else if(i % 3 == 1) {
employee[i] = new MonthWorker();
}
else if(i % 3 == 2) {
employee[i] = new WeekWorker();
}
}
Company company = new Company(employee);
System.out.println("公司年工资总额:" + company.salariesPay());
}
}
运行结果：
公司年工资总额:0.0
Q3: Java编程（写出程序代码）
写了一个代码，代码如下，可以进行参考
public class sum {
public static void main(String[] args) {
//创建一个Scanner的对象input
Scanner input = new Scanner(System.in);
//提示用户输入数据
System.out.print("请输入一个整数");
//将输入的值赋给n
int n = input.nextInt();
//定义变量接收计算后的和
int sum = 0;
//利用循环进行求和
for (int i = 0; i = n; i++) {
sum+=i;
}
//输出最后的和
System.out.println("从0一直到"+n+"的所有整数的和是:"+sum);
}
}
