Passing file path as an argument through a Method in Java

In this Article  , I will step through the sample code , and show you how to create a Method to accept File Path as an Argument.

 

</pre>
package tryresources;

import java.io.BufferedReader;
import java.io.PrintWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;

public class accessFile {

// Declare 100 length for array "files"
static File[] files = new File[100];
// Declare 100 length for array "bReaders"
static BufferedReader[] bReaders= new BufferedReader[100];
// Initial Value For size"
static int size =0;
// Initial Value For size2"
static int size2 =0;
// Where the File is located
static String desc ="C:/Users/User/Desktop/textFile.txt";





//-----------Reading File ( Method) -------------------------------------------------------
public static void readingFile(String fz)

{


// Every time the Method is being Call , add one to the Size
size = size +1;


//then create A New File instance base on the new size

files[size] = new File(fz);

// Every time the Method is being Call , add one to the Size
size2 = size2 +1;



//then create A New BufferReeader instance base on the Inputed length




try {

//Create New BufferedReader Instance " bReaders)
bReaders[size2] = new BufferedReader(new FileReader(files[size]));

String line;

//Create a new new BufferedReader object named br by reading the new instant file

while ((line = bReaders[size2].readLine()) != null) {

// while bufferReader are able to read some line in the File , Print out the content
// in the File

System.out.println(line);
}
} catch (FileNotFoundException e) {

System.out.println("Can't find file " + files[size].toString());
} catch (IOException e) {

System.out.println("Unable to read file " + files[size].toString());
}

finally {
// releases all system resources from the streams

try {
bReaders[size2].close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}





public static void main(String[] args) {

// First will Read the File
readingFile(desc);

// Write Something to the File
PrintWriter writer1 =null;
try {
writer1 = new PrintWriter(new File(desc));
} catch (FileNotFoundException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
writer1.write("I Like Java.");
writer1.flush();
writer1.close();

// Read the newly overwrite Value

readingFile(desc);

}

}
