What are keywords?

Rating:

Every computer language uses some reserved words known as keywords. They are an essential part of the language. In Java, keywords are defined in lower case and cannot be used as identifiers.

The table given below shows the list of keywords used in the Java language:

abstract	assert	boolean	break	byte	case	catch
char	class	const	continue	default	do	double
else	extends	final	finally	float	for	goto
if	implements	import	instanceof	int	interface	long
native	new	package	private	protected	public	return
short	static	strictfp	super	switch	synchronized	this
throw	throws	transient	try	void	volatile	while

The keywords 'const' and 'goto' have not yet been implemented in Java. Java has reserved them for use in future expansion of the language.

Note: In addition to the keywords shown in the table, Java reserves the boolean values (true and false) and the reference value (null) for its own use.
