高分求两个简单的JAVA设计源代码

上面 wuzhikun12同学写的不错，但我想还不能运行，并且还不太完善。我给个能运行的：（注意：文件名为：Test.java)

//要实现对象间的比较，就必须实现Comparable接口，它里面有个compareTo方法

//Comparable最好使用泛型，这样，无论是速度还是代码量都会减少

@SuppressWarnings("unchecked")

class Student implements ComparableStudent{

private String studentNo; //学号

private String studentName; //姓名

private double englishScore; //英语成绩

private double computerScore; //计算机成绩

private double mathScore; //数学成绩

private double totalScore; //总成绩

//空构造函数

public Student() {}

//构造函数

public Student(String studentNo,String studentName,double englishSocre,double computerScore,double mathScore) {

this.studentNo = studentNo;

this.studentName = studentName;

this.englishScore = englishSocre;

this.computerScore = computerScore;

this.mathScore = mathScore;

}

//计算总成绩

public double sum() {

this.totalScore = englishScore+computerScore+mathScore;

return totalScore;

}

//计算评测成绩

public double testScore() {

return sum()/3;

}

//实现compareTO方法

@Override

public int compareTo(Student student) {

double studentTotal = student.getTotalScore();

return totalScore==studentTotal?0:(totalScorestudentTotal?1:-1);

}

//重写toString方法

Student student = (Student)obj;

if(this.studentNo.equals(student.getStudentName())) { //照现实来说，比较是不是同一个学生，应该只是看他的学号是不是相同

return true;

} else {

return false;

}

}

/*以下为get和set方法，我个人认为，totalScore的set的方法没必要要，因为它是由其它成绩计算出来的

在set方法中，没设置一次值，调用一次sum方法，即重新计算总成绩

for(int i = 0 ; istudents.length; i++){

double avgScore = students[i].testScore();

System.out.println(students[i].getStudentName()+"学生的评测成绩为："+ avgScore+"分");

}

}

}

运行结果为：

张三学生的评测成绩为：69.66666666666667分

李四学生的评测成绩为：80.5分

王五学生的评测成绩为：78.0分

李六学生的评测成绩为：98.5分

朱漆学生的评测成绩为：60.03333333333333分

求一个简单java程序代码，谢谢

public class TestStar {

public static void main(String[] args) {

String star = "*";

for (int i = 0; i 5; i++) {

if (i == 0) {

System.out.print(" " + star);

System.out.println();

}

if (i == 1) {

for (int z = 0; z 4; z++) {

System.out.print(" " + star);

}

System.out.println();

}

if (i == 2) {

System.out.print(" ");

for (int x = 0; x 3; x++) {

System.out.print(" " + star);

}

System.out.println();

}

if (i == 3) {

for (int y = 0; y 2; y++) {

System.out.print(" " + star + " ");

}

}

}

}

}

是好使的 但是我没找到画五角星有什么规律（五角星好象不是正规图形吧？）如果还有什么要求的话 补充问题(如果是用*填充所有的东西 不包括 “ ”的话 我可以重新再给你写一个)

java猜数字游戏怎么怎么做到在游戏结束后输入y重新开始输入n退出游戏？下面是源代码

while(true){

//你的程序

System.out.println("再玩一次？");

String st= scan.next();

if( st=="y")｛continue;｝

if( st=="n")｛break;｝

System.out.println("既不是y也不是n，出错");

}

java 数独(性质求简单代码)

这只是一个找规律的题而已，找好规律了，谁都会做。

import java.util.Arrays;

import java.util.Scanner;

public class Kuaile {

public static void main(String[] args) {

System.out.println("请输入一个=34的数:");

Scanner in = new Scanner(System.in);

int num = in.nextInt();

while (num 34) {

System.out.println("数值太小了！请重输：");

num = in.nextInt();

}

int row1[] = { 8, 11, num - 20, 1 };

int row2[] = { num - 21, 2, 7, 12 };

int row3[] = { 3, num - 18, 9, 6 };

int row4[] = { 10, 5, 4, num - 19 };

System.out.println(Arrays.toString(row1));

System.out.println(Arrays.toString(row2));

System.out.println(Arrays.toString(row3));

System.out.println(Arrays.toString(row4));

}
