try


The try keyword is used to enclose blocks of statements that might throw exceptions. Every try block must have at least one catch or finally clause. If a particular exception class is not handled by any catch clause, the exception propagates up the call stack to the next enclosing try block, recursively.

Syntax:
try
{

}
catch ( e)
{

}
finally
{

}


Example:

public void divide(int numberToDivide, int numberToDivideBy)
    throws BadNumberException{
        if(numberToDivideBy == 0){
            throw new BadNumberException("Cannot divide by 0");
        }
        return numberToDivide / numberToDivideBy;
    }
