Keywords in JAVA

Keywords are the reserved words in java. They cannot be use to name variables, constants, classes, objects, methods etc… There are 50 keywords in java.

abstract	assert	boolean	break	byte
case	catch	char	class	const
continue	default	do	double	else
enum	extends	final	finally	float
for	goto	if	implement	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

In addition to above keywords, java reserves following words: true, false and null. These values are defined by java. So you can’t use true, false and null for names of variables, classes and so on.
