-:Java Statements :-
-> The Statement in Java are like sentences in natural languages.
-> A Statement is executable combination of tokens ending with a Semicolon (;) mark.
-> Statements are usually executed in Sequence in the order in which they appear.
-> However, it is possible to control the flow of execution, if necessary, using special
Classification of Java Statements
1: Empty Statement :- These do nothing and are used during program development as a place holder.
2: Labelled Statement :- Any Statement may begin with a label must not be keywords, already declared local labels variables or previously used labels in this module.
->In Java used as the arguments of Jump Statements, which are described later in this list.
3:- Expression Statement :- most Statements are expression statements.
->Java program has seven types of Expression -statements:-
*Assignment Statement
*Pre-Increment
*Pre-decrement
*post-Increment
*Post-decrement
*Method call and
*Expression
4:- Control Statements:- are used to control the flow of execution of a program based on certain conditions.
5:- Selection Statement :- These select one of several control flows.There are 3 types of selection statements in Java.
*if
*If-else
*Switch
6:-Iteration statements:- These specify how and when looping will take place.there are three types of Iteration statements.
*While
*do
*for
7:-Jump Statements :- they pass control to the beginning orend of the current block,or to a labelled statement.
->Such labels must be in the same block, and continue labels must be on a Iteration statements.
-> the four types of Jump Statements are :-
*break
*continue
*return and
*throw
8:- Synchronization Statements :- These are used for handling with threading.
9:-Guarding Statements :-guarding statements are used for safe handling of code that may be cause exceptions (such as division by zero ).
->These statements use the keywords try, catch, and finally
