import
java.io.*;
public class Mine{
public static void main(String argv[]){
Mine m=new Mine();
System.out.println(m.amethod());
}
public int amethod(){
try{
FileInputStream dis =new FileInputStream("Hello.txt"); //1,抛出异常
}catch ( Exception ex) {
System.out.println("No such file found"); //2.catch捕获异常,并执行
return -1; //4,return 返回
}finally{
System.out.println("Doing finally"); //3.finally一定会执行,在return之前。
}
return 0;
}
}
运行结果:
C:\java>java Mine
No such file found
Doing finally
-1
