What is White Space? explain proper use of white space in java?

White space consists mainly of the space character in which you generates through hitting the space bar on your keyboard and in which is generally used to separate words within sentences. There are four other white space characters in Java, the horizontal tab, the create feed, the carriage return, and the linefeed. Depending on your platform, while you hit the return or enter key, you obtain either a carriage return (the Mac), a linefeed (Unix) or both (DOS, Windows, VMS). This generates a hard line break within the source code text.
Outside of String literals Java treats all white space and runs of white space (more than one white space character within immediate succession) the similar. It's used to separate tokens, and one space is as excellent as seven spaces, a tab and two carriage returns. Exactly that white space characters you use is primarily a result of what's convenient for human beings reading the code. The compiler doesn't care.

Inside String and character literals the just white space permitted is the space character. Carriage returns, tabs, line feeds and form feeds must be inserted along with special escape sequences like \r, \t, \f, and \n. You cannot break a String across a line like this:

String poem = "Mary had a little lamb
whose fleece was white as snow
and everywhere that Mary went
the lamb was sure to go.";
Instead you must use \n and the string concatenation operator, +, like this:
String poem = "Mary had a little lamb\n" +
"whose fleece was white as snow\n" +
"and everywhere that Mary went\n" +
"the lamb was sure to go.";

Remember that you can break a statement across multiple lines, you only can't break a String literal.
Also note that \n only works on Unix. You should probably use System.getProperty("line.separator") instead to return the proper line separator string for the platform your program is running on.

Java does not have all the escape sequences C has. Besides those already described it has only \b for backspace, \\ for the backslash character itself.

There are also \u escapes in which let you include any Unicode character.

The proper use of white space in programs
• Blank lines to separate blocks
• Use spaces instead of tabs
