What is try block?
A ‘try’ block in java is construct used to wrap a section of code that might throw an exception.Its primary purpose is to define a scope where exceptions can be caught and handled, allowing the program to continue executing or terminating gracefully.’try’ block must be followed by at least one ‘catch’ block or a’finally’ block or both.
What is catch block?
A ‘catch’ block in java is used to handle exceptions that occur in the associated ‘try’ block.when an exception is thrown in the ‘try’ block,the runtime system looks for a corresponding ‘catch’ block that can handle that type of exception.
what is Finally block?
A finally block in java is used to execute code after a ‘try’ block and its corresponding ‘catch’ block, regardless of whether an exception was thrown or caught.
The finally ‘finally’ block is typically used for cleanup activities such as closing files, releasing resources and other termination procedures that must happen even if an error occurs.
syntax:

}catch (ExceptionType2 e2){
}
2.Try with Finally:
try{
}finally{
}
3.Try with catch and finally:
try{
} catch (ExceptionType e){
} finally{
}
Example without catch or finally:
try{
int result=10/0;
}
