这是我照着书上写的 可运行总是错误 不解 希望大家帮帮忙..... class NewThread implements Runnable{
Thread t; NewThread(){
//Create a new ,second thread
t=new Thread(this,"Demo Thread");
System.out.println("Child thread:"+t);
t.start();
} public void run(){
try{
for(int i=5;i>0;i--){
System.out.println("Child Thread:"+i);
Thread.sleep(500);
}
}catch (InterruptedException e){
System.out.println("Child interrupted.");
}
}System.out.println("Exiting child thread.");
}
public class Thread { /**
* @param args
*/
public static void main(String[] args) { // TODO Auto-generated method stub
new NewThread();
try{
for(int i=5;i>0;i--){
System.out.println("Main Thread:"+i);
Thread.sleep(1000);
}
}catch(InterruptedException e){
System.out.println("Main thread interrupted.");
}
System.out.println("Main thread exiting.");
} }
还有一个是copy论坛上的 可还是错
String s="";
int n=0;
try{
BufferedReader in =new BufferedReader(new InputStreamReader(System.in));
System.out.println("input a number:");
s=in.readLine();//r 小写
n=Integer.parseInt(s);//不好意思,上面写错了 parseInt中i大写
}
catch(IOException e) {}
System.out.println("you input a "+n);说BufferedReader cannot be resolved to a type
