Question { 992 }

What are the differences between unchecked exception, checked exception, and errors?

Answer

• An Unchecked exception inherits from RuntimeException (which extends from exception). The JVM treats RuntimeException differently as there is no requirement for the application code to deal with them explicitly.
• A checked exception inherits from the exception class. The client code has to handle the checked exceptions either in a try-catch clause or has to be thrown for the super-class to catch the same. A checked exception thrown by a lower class (sub-class) enforces a contract on the invoking class (super-class) to catch or throw it.
• Errors (members of the error family) usually appear for more serious problems, such as OutOfMemoryError (OOM), that may not be so easy to handle.

Question { 767 }

What are the types of loops in Java, and how are they used?

Answer

• In Java, for loops are used to repeatedly run statements for a specified number of times. When a programmer knows how many times to run a statement, they use a for loop.
•When some statements must run continuously until a condition is met, the while loop can be helpful. Before statements are executed in while loops, the condition is checked.
•With the exception of checking the condition after a block of statements has been executed, the do while loop is identical to the while loop. Do while loop statements should also run at least once.
