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

return true;
} else {

}
}
/*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

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));
}
