use the following code.don`t forget to import java.io.* BufferedReader br=new BufferedReader(new InputStreamReader(System.in));String str=br.readLine(); ps:the above code can throw an IOException.

Wait...I think this is code used in console program, isn't it ?, when we want to read input from keyboard.But if I use it to read a file content, so, where I must give the "file name argument" ?

try

{

BufferedReader br = new BufferedReader(new FileReader("MyFile.txt"));

String line = br.readLine();

}

catch(FileNotFoundException fnfe)

{

System.out.println("File MyFile.txt not found.");

}

catch(IOException ioe)

{

System.out.println("Unable to read from MyFile.txt");

}

The code previously suggested will only get you the first line. Try this instread:

try

{

BufferedReader br = new BufferedReader(new FileReader("MyFile.txt"));

StringBuffer line = new StringBuffer();

String temp = null;

while( ( temp = br.readLine() ) != null )

{

line.append( temp );

}

// Then use line.toString() to convert to a String.

}

catch(FileNotFoundException fnfe)

{

System.out.println("File MyFile.txt not found.");

}

catch(IOException ioe)

{

System.out.println("Unable to read from MyFile.txt");

}
