Does it matter in what order catch statements for FileNotFoundException and IOException are written?
Anandvijayakumar
Yes, it does. The child exceptions classes must always be caught first and the "Exception" class should be caught last

Explain about exception handling with multiple exception?
Exception handling in Java is done through a try-catch-finally block. The "try" block of code is where you put the code which may throw an exception. The "catch" block of code is where you put the code which will execute after an exception is thrown in the try block. This is often used to display an error message, or to mitigate problems caused by the exception. The "finally" block is where you put code that you want to execute after the try and catch blocks have been processed. // example code for catching exception while reading from a file try { // this line of code can throw a FileNotFoundException FileReader in = new FileReader("myfile.txt"); // this line of code can throw an IOException in.read(); } catch(FileNotFoundException ex) { // catch first exception type System.err.println("Cannot find myfile.txt!"); } catch(IOException ex) { //catch second exception type System.err.println("Cannot read from myfile.txt!"); } finally { // no matter what we want to close the file, so do it here // however, this line can also cause an exception, so we need to catch that, too try { in.close(); catch(IOException ex) { // not much we can do about an exception that occurs here } }
What is the repetitive control structure in c plus plus?
C provides two sytles of flow control:BranchingLoopingBranching is deciding what actions to take and looping is deciding how many times to take a certain action. Branching: Branching is so called because the program chooses to follow one branch or another.if statementThis is the most simple form of the branching statements. It takes an expression in parenthesis and an statement or block of statements. if the expression is true then the statement or block of statements gets executed otherwise these statements are skipped.? : OperatorThe ? : operator is just like an if ... else statement except that because it is an operator you can use it within expressions. ? : is a ternary operator in that it takes three values, this is the only ternary operator C has.switch statement:The switch statement is much like a nested if .. else statement. Its mostly a matter of preference which you use, switch statement can be slightly more efficient and easier to read. Using break keyword:If a condition is met in switch case then execution continues on into the next case clause also if it is not explicitly specified that the execution should exit the switch statement. This is achieved by using break keyword. Try out given example Show ExampleWhat is default condition:If none of the listed conditions is met then default condition executed. Looping Loops provide a way to repeat commands and control how many times they are repeated. C provides a number of looping way. while loopThe most basic loop in C is the while loop.A while statement is like a repeating if statement. Like an If statement, if the test condition is true: the statements get executed. The difference is that after the statements have been executed, the test condition is checked again. If it is still true the statements get executed again.This cycle repeats until the test condition evaluates to false. for loopfor loop is similar to while, it's just written differently. for statements are often used to proccess lists such a range of numbers: do...while loopdo ... while is just like a while loop except that the test condition is checked at the end of the loop rather than the start. This has the effect that the content of the loop are always executed at least once. break and continue statements C provides two commands to control how we loop: break -- exit form loop or switch.continue -- skip 1 iteration of loop.
What is difference between static dll and build dll?
static in the computer world means: constant, never changing So, the opposites in the computer world (rapidly changing) could be: dynamic, build, recompile, etc. So, no matter what the object, static would make it "never changing". For instance, some programs are written to stay the same--never change. That would be static. Some programs could be written to pull variables from tables, ftp jobs, etc, where the program does different courses of action based on "if" statements. So, static dll are commands that never change. They only mean one thing. Build dll would compile every time to pick up any changes it needed.
Control statements in java?
A programming language uses control statements to cause the flow of execution to advance and branch based on changes to the state of a program. control statements are mainly three types in java. they are selection, iteration, and jump.

Plasma is probably the answer you're looking for, although it is still baryonic matter, but it is not like the usual matter found on Earth.
Does it matter in what order catch statements for FileNotFoundException and IOExceptipon are written?
Catch statements are evaluated in the order in which they are written. Therefore, the more specific exception should be caught first. (If one exception is a subclass of another one, catch it first.)
