Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "To check whether Java is installed in our machine, navigate to C:\Program Files."

A block of code is set as follows:

package coreJava;
public class finaldemo {
           public static void main(String[] args) {
               //TODO Auto-generated method stub

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

protected void abc() {
    //TODO Auto-generated method stub
  System.out.println("Hello");
}

Any command-line input or output is written as follows:

$ import package.classname

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Keep clicking on Next so that Java is successfully configured in our machine."
