Thread: Urgent - File exist nor working

Take a look at this example. You will be able to adapt it to suit your needs.

		String fullName = "C:\\JavaPF\\input.txt";		
		File file = new File(fullName);
 
		if(file.exists()){
			System.out.println("File exists");
		}	
		else{
			System.out.println("File doesn't exist");
			// write file
		}

I just realized how wrong I am about what i had written here before. Here is the new question: How do i get Java to create a new text file for me? and what happens when i try to create a file that already exists?

File file = new File(fullName);

this will only create a file object, but i want it to create a file .txt file in a folder i specified.

I will give you some code on how to create the file, but I do recommend you become familiar with the API and tutorial links I posted above, going through the examples and playing with them to understand what is going on so you can use those code examples in your programs - this process is essential to learn the language, together with problem solving in the context of the language.

File file = new File(myFilePath);
if ( !file.exists() ){
    file.create();
}else{
///file already exists...perhaps you wish to warn the user that the file exists
}

If you wish to write to the file, you must create a Writer, for example creating a BufferedWriter

BufferedWriter writer = null;
try{
    writer = new BufferedWriter(new FileWriter(file) );
    //write to file
}catch(Exception e){
    //deal with exception
}finally{
    if ( writer != null ){
        try{writer.close();}catch(Exception e){}
    }
}
