try catch finally与return的执行顺序

核心提示: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{

  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捕捉异常,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
