Stream Object Initialization

[mahinkhan22]

Now I am getting compile time error at line 30 and 38 that 'fin' might not have been initialized. but its perfectly to write it this way

import java.io.*;
class CopyFile {
	public static void main(String args[]) throws IOException {
		int i;
		FileInputStream fin;
		FileOutputStream fout= new FileOutputStream(args[1]);

		try{
			//open input file
			try{
				fin = new FileInputStream(args[0]);
			}
			catch(FileNotFoundException e){
				System.out.println("Input file Not Found");
				return;
			}
			//open output file
			try{
				fout = new FileOutputStream(args[1]);
			}
			catch(FileNotFoundException e){
				System.out.println("Error Opening File");
			}
		}
		catch(ArrayIndexOutOfBoundsException e){
			System.out.println("usage: Copyfile From to");
		}
		try{
			do{
				i = fin.read();
				if(i!= -1)
					fout.write(i);
			}while(i != -1);
		}
		catch(IOException e){
			System.out.println("file error");
		}
		fin.close();
		fout.close();
	}
}

It`s a local variable! Try to write FileInputStream fin = null; in line 5
