JAVA网络及数据库开发

用Thread类和Runnable接口实现在控制台上打印大写A—Z和它的ASC||码。要求：第一个类继承Thread类并打印字母。第二个类实现Runnable接口打印ASC||码，在Main类里只能启动第一个线程，而第二个线程要求在第一个线程中启动，第一个线程要求把ASC||码传给第二个线程。

Answer 1

public class PrintThread extends Thread{

private String s = "abcdefghijklmnopqrstuvwxyz";

@Override
public void run(){
char[] cc = s.toCharArray();
int[] ii = new int[26];
for(int i = 0; i < cc.length; i++){
System.out.print(cc[i]);
System.out.print(" ");
}
System.out.println();

for(int i = 0; i < cc.length; i++){
ii[i] = (int)cc[i];
System.out.print(ii[i]);
System.out.print(" ");
}

System.out.println();

new Thread(new PrintRunable(ii)).start();

}

public static void main(String[] args) {
new PrintThread().start();
}
}

class PrintRunable implements Runnable{

private int[] cc = new int[26];

public PrintRunable(int[] cc){
this.cc = cc;
}

@Override
public void run() {
for(int i = 0; i < cc.length; i++){
System.out.print(cc[i]);
System.out.print(" ");
}
}
}
