What is the use of catch keyword ?

Answer 1

A catch block is where you handle the exceptions, this block must follow the try block. A single try block can have several catch blocks associated with it. You can catch different exceptions in different catch blocks. When an exception occurs in try block, the corresponding catch block that handles that particular exception executes. For example if an arithmetic exception occurs in try block then the statements enclosed in catch block for arithmetic exception executes.

Answer 3

what kind of exceptions ???

Answer 4

yeah..I want it in c++
I don't know java

Answer 5

thnx kamal

Answer 6

Say suppose you want to build a program for basic division. But what if the user inputs "0" in the denomintor. To handle such a situation exception handling is used. Such situations are called exceptions.
main()
{
int a= 10,b = 0;
int c;
try{
if(b == 0)
throw b;
c= a/b;
cout<<c;
}
catch(const int a)
{
cout<<"exception!! divide by "<<a;
}
}
Here "try" is used to check if denominator is 0.
"throw" is used to throw exception if it occurs,else program executes normally.
If exception is present, then control moves to the catch block, and s message is displayed that it is divide by zero exception.We call it as "exception caught".
I hope it helps.

Answer 7

Exceptions provide a way to transfer control from one part of a program to another. C++ exception handling is built upon three keywords: try, catch, and throw.

Answer 8

try{
Scanenr sc = new Scanner(System.in);
int x;
System.out.println("Enter a number: ");
x = sc.nextInt();
}catch (Exception e){
System.out.println("Enter a Number!");
}
/*i
f th user Enters a String insted of an Interger then the erro will accure.

You can also set it as:

catch(Exception e){
System.out.println(e);
}
/* this will print out the error that has been picked up by the compiler occured during the compiling. Sorry forr duing it in java If you want it in C++ tell me and I will give you an example
