file.java

对于简单的异常处理源码

import java.io.*;
class File{
	public static void main(String[] args){
		try{
			FileWriter w=new FileWriter("c:\\file.txt");
			w.write("hello!");
			w.close();
		}catch(Exception e){
			System.out.println("Exception");
			e.printStackTrace();
		}
		
		try{
			FileReader r=new FileReader("c:\\file.txt");
			char c[]=new char[128];
			r.read(c);
			String s=new String(c);
			System.out.print(s);
			r.close();
		}catch(Exception e){
			System.out.println("Exception");
			e.printStackTrace();
		}
	}
}
