帮忙写个java的练习题代码，万分感谢！！！
public class myTest
{
public static void main(String[] args)
{
String[] strArr = { "010", "3223", "666", "7890987", "123123" };
System.out.println(getSymmetricString(strArr));
}
public static String getSymmetricString(String[] strArr)
{
String allInfo = "";
int sum = 0;
for (String str : strArr)
{
boolean flag = true;
for (int i = 0; i str.length() / 2; i++)
{
String bgnStr = str.substring(i, i + 1);
String endStr = str.substring(str.length() - (i + 1), str.length() - i);
if (!bgnStr.equals(endStr))
{
flag = false;
break;
}
}
if (flag)
{
allInfo = allInfo + str + "是对称巩固java习题代码的巩固java习题代码，对称巩固java习题代码的数量为巩固java习题代码：" + str.length() / 2 + "\n";

Q1: java练习题求完整代码
按照题目要求编写巩固java习题代码的用javaBean规范设计巩固java习题代码的学生类Student巩固java习题代码的Java程序如下
需要创建user.java.test包,把Student.java文件和Test.java文件放入包中,编译Student.java文件并且编译运行Test.java文件得到运行结果
Student.java文件代码如下
package user.java.test;
import java.io.Serializable;
public class Student implements Serializable{
private static final long serialVersionUID = 1L;
private String no;
private String name;
private double score;
public Student(){}
public Student(String no,String name,double score){
this.no=no;
this.name=name;
this.score=score;
}
public String getNo(){ return no;}
public void setNo(String no){ this.no=no;}
public String getName(){ return name;}
public void setName(String name){ this.name=name;}
public double getScore(){ return score;}
public void setScore(double score){ this.score=score;}
public String toString(){
return "学号:"+no+",姓名:"+name+",成绩:"+score;
}
public static double getAvg(Student[] sArray){
double sum=0,avg;
for(int i=0;isArray.length;i++){
sum=sum+sArray[i].getScore();
}
avg=sum/sArray.length;
return avg;
}
}
Test.java文件代码如下
package user.java.test;
public class Test{
public static void main(String[] args){
Student[] sArray=new Student[5];
sArray[0]=new Student("001","张三",89.5);
sArray[1]=new Student("002","李四",82.5);
sArray[2]=new Student("003","王五",93);
sArray[3]=new Student("004","赵六",73.5);
sArray[4]=new Student("005","孙七",66);
System.out.println("这些学生的平均分:"+Student.getAvg(sArray));
for(int i=0;isArray.length;i++){
System.out.println(sArray[i].toString());
}
}
}
Q2: java练习题求解希望有完整代码
运行代码
具体的代码如下：
import java.util.HashMap;
public class SearchDemo {
public HashMapInteger,Integer countMap(char[] arr){
HashMap countMap = new HashMapInteger, Integer();
for (int i = 0; i arr.length; i++) {
if(!countMap.containsKey(arr[i])){
countMap.put(arr[i],1);
}else{
int value = (int)countMap.get(arr[i]) + 1;
countMap.put(arr[i],value);
}
}
return countMap;
}
public static void main(String[] args) {
char[] arr={'A','1','R','!','e','','A','5','A','g','#','D'};
int count = new SearchDemo().countMap(arr).get('A');
System.out.println("其中'A'字符的个数是：" + count);
}
}
运行结果
