Question

when I write this piece of

String path="d:\\test.txt";
    boolean chk;
    File f=new File(path);

    try
    {
        chk=f.createNewFile();
    }catch(IOException e)
    {
        chk=false;
        e.printStackTrace();
    }


    if(chk)
        System.out.println("file created.");
    else
        System.out.println("file not created");

file is created in d-drive

but when I use this

String path="d:\\test.txt";
    File f=new File(path);

    if(f.createNewFile())
        System.out.println("file created.");
    else
        System.out.println("file not created");

it throws exception.

Please enlighten me on this

Change second part of you code to following:

                    String path = "d:\\test.txt";
                    File f = new File(path);

                    try {
                        if (f.createNewFile())
                            System.out.println("file created.");
                        else
                            System.out.println("file not created");
                    } catch (IOException e1) {
                        e1.printStackTrace();
                    }

You are required to do this because if you don’t surrond f.createNewFile() within try/catch block, your code won’t compile. As usage of f.createNewFile() throws IOException you need to either put it in try/catch block catching IOException or method using this part of code needs to declare throws IOException.
