try catch finally与return的执行顺序
2008-01-05 08:46:44 来源:WEB开发网核心提示: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
