The cursor types are listed least to most resource intensive. There Forward Only Fastest can only move forward in recordset. There static can move to any record within the recordset.

Conditional operator: It is an operator taking three operands that is, a ternary operator. The conditional operator (?:) is employed in the form bexpr ? expr1 : expr2 Q : Explain Cast Cast : Where Java does not Cast: Where Java does not allow the utilization of a source value of one type, it is essential to use a cast to force the compiler to admit the use for the target type. The care must be taken with casting values of primitive types, as this frequently
