The flow control statements give you to conditionally execute statements, to repeatedly operate a block of statements, or to just modify the sequential flow of control.
Looping
while, do-while, for
The body of the while loop is run only if the expression is true, so it cannot be executed even once:
while(i < 5){...}
The body of the do-while loop is run at least once because the test expression is evaluated only after executing the loop body. Also, don't forget the ending semicolon after the while expression.
do { ... } while(i < 5);
The for loop syntax is:
for(expr1; expr2; expr3)
{
// body
}
expr1 Æ is for initialization, expr2 Æ is the conditional test, and expr3 Æ is the iteration expression. Any of these sections may be omitted and the syntax will still be legal:
for( ; ; ) {} // an endless loop
Decision making
if-else, switch-case
The if-else statement is used for decision-making -- that is, it decides which course of action have to be taken.
if (x == 5) {...} else {..}
The switch statement is also used for decision-making, based on an integer expression. The argument passed to the switch and case statements could be int, char, short, or byte. The argument passed to the case statement could be a literal or a final variable. If no case matches, the default statement (which is optional) is executed.
int i = 1;
switch(i)
case 0:
System.out.println("Zero");break; //if break; is omitted case 1: also executed
case 1:
System.out.println("One");break; //if break; is omitted default: also executed
default: System.out.println("Default");break;
Branching
break, continue, label:, return
The break statement is needed to exit from a loop or switch statement, while the continue statement is needed to skip just the current iteration and continue with the next. The return is used to return from a function based on a condition. The label statements may lead to unreadable and unmaintainable spaghetti code hence should be avoided.
Exception handling
try-catch-finally, throw
Exceptions may be used to define ordinary flow control. This is a misuse of the idea of exceptions, which are meant only for exceptional conditions and hence should be avoided.

One of the principal benefits of JMS messaging is that it's asynchronous. Thus not all the pieces require to be up all the time for the application to function as a whole.
The == gives true, if the variable reference points to the similar types of object in memory. That is a " shallow comparison ". The equals () - gives the results of run
