thread1_ex.java

刘艺编著的java教程的课本习题加例题代码 很有用哦！

public class Thread1_ex extends Thread{
  char c;
  public Thread1_ex(String name,char c){
   super(name);
   this.c=c;
  }
  public void run(){
    int k;
    char ch=c;
    System.out.println();
    System.out.print(getName()+":  ");
    for(k=0;k<=25;k++){
     ch=(char)(c+k);
     System.out.print(ch+" ");
    }
    System.out.println(getName()+" end!");
  }
  public static void main(String args[]){
   Thread1_ex th1=new Thread1_ex("th1",'A');
   Thread1_ex th2=new Thread1_ex("th2",'a');
   th1.start();
   th2.start();
   System.out.println("activecount="+Thread.activeCount());
  }
}
