Statements

Lines of Java code are classified as either declarations or statements.

• A declaration provides information to Java. For example, the declaration
       int count;
  tells Java that the variable named count will be used to hold integer values.
  
  
• A statement tells Java to do something. For example, the assignment statement
       count = 0;
  tells Java to set the variable count to zero. (Statements are more accurately called "commands," but this term is rarely used.)

Just to confuse things, the two can be combined in an "initializing declaration," for example,
     int count = 0;
or even
     String result = someOtherString.substring(0, 5);
(these are still considered declarations).

Here are the types of statements available in Java:

assignment statements	for loops
assert statements	if statements
blocks	print statements
break statements	return statements
continue statements	switch statements
do-while loops	try statements
enhanced for loops	while loops
expressions
