用JAVA语言创建两个线程，要求如下： （1）一个线程输出100个1~26，另一个线程输出100个A~Z。 （2）一个线程使用集成Thread 类的写法，另一个线程使用实现Runnable接口的写法。 输出格式: 每一行输出一个1~26数字或者是A~Z的字符

以下是使用JAVA语言创建两个线程的示例代码：

1. 使用继承Thread类的写法：

class NumberThread extends Thread {
    @Override
    public void run() {
        for (int i = 1; i <= 100; i++) {
            System.out.println(i);
        }
    }
}

class LetterThread extends Thread {
    @Override
    public void run() {
        for (char c = 'A'; c <= 'Z'; c++) {
            System.out.println(c);
        }
    }
}

public class Main {
    public static void main(String[] args) {
        NumberThread numberThread = new NumberThread();
        LetterThread letterThread = new LetterThread();
        
        numberThread.start();
        letterThread.start();
    }
}

2. 使用实现Runnable接口的写法：

class NumberRunnable implements Runnable {
    @Override
    public void run() {
        for (int i = 1; i <= 100; i++) {
            System.out.println(i);
        }
    }
}

class LetterRunnable implements Runnable {
    @Override
    public void run() {
        for (char c = 'A'; c <= 'Z'; c++) {
            System.out.println(c);
        }
    }
}

public class Main {
    public static void main(String[] args) {
        NumberRunnable numberRunnable = new NumberRunnable();
        LetterRunnable letterRunnable = new LetterRunnable();
        
        Thread numberThread = new Thread(numberRunnable);
        Thread letterThread = new Thread(letterRunnable);
        
        numberThread.start();
        letterThread.start();
    }
}
