主线程打印25个希腊字母,创建两个线程,一个线程打印“A”-“Z”26个字母,另一个线程打印“0”-“9”10个数字。要求如下: (1)用Thead类的子类创建线程。 (2)实现Runnable接口,再用Thread类直接创建线程。 以上两种创建方式都要实现。

很抱歉,我是一个人工智能语言模型,无法执行您提出的设计任务。但我可以为您提供一些代码示例,用以参考。以下是使用Thread类的子类创建线程的示例代码:
```
import java.util.ArrayList;
import java.util.List;
public class MainThread extends Thread {
public void run() {
for(int i = 0; i < 25; i++) {
char letter = (char)('α' + i);
System.out.print(letter + " ");
}
}
public static void main(String[] args) {
MainThread mainThread = new MainThread();
Thread thread1 = new Thread(new AlphabetThread());
Thread thread2 = new Thread(new NumberThread());
mainThread.start();
thread1.start();
thread2.start();
}
}
class AlphabetThread implements Runnable {
public void run() {
for(char letter = 'A'; letter <= 'Z'; letter++) {
System.out.print(letter + " ");
}
}
}
class NumberThread implements Runnable {
public void run() {
for(int i = 0; i < 10; i++) {
System.out.print(i + " ");
}
}
}
```
以下是使用实现Runnable接口的方式创建线程的示例代码:
```
import java.util.ArrayList;
import java.util.List;
public class MainThread {
public static void main(String[] args) {
Thread thread1 = new Thread(new Runnable() {
public void run() {
for(char letter = 'A'; letter <= 'Z'; letter++) {
System.out.print(letter + " ");
}
}
});
Thread thread2 = new Thread(new Runnable() {
public void run() {
for(int i = 0; i < 10; i++) {
System.out.print(i + " ");
}
}
});
Thread mainThread = Thread.currentThread();
mainThread.setName("MainThread");
thread1.start();
thread2.start();
for(int i = 0; i < 25; i++) {
char letter = (char)('α' + i);
System.out.print(letter + " ");
}
}
}
```
