You responsible for maintaining an application that was written by a former colleague at XYZ. The application reads from and writes to log files located on the local network. The original author included the following debugging code to facilitate maintenance: try {
Debug.WriteLine(“Inside Try”);
throw(new IOException());}
catch (IOException e) {
Debug.WriteLine (“IOException Caught”);}
catch (Exception e) {
Debug.WriteLine(“Exception Caught”);}.
finally {
Debug.WriteLine (“Inside Finally”);}
Debug.WriteLine (“After End Try”); Which output is produced by thus code?
Given the following piece of code:
class SalaryCalculationException extends Exception{}class Person{ public void calculateSalary() throws SalaryCalculationException{ //... throw new SalaryCalculationException(); //... }}class Company{ public void paySalaries(){ new Person().calculateSalary(); }}

Which of the following statements is correct?
1. This code will compile without any problems.
2. This code will compile if in method paySalaries() we return a boolean in stead of void.
3. This code will compile if we add a try-catch block in paySalaries().
4. This code will compile if we add throws SalaryCalculationException in the signature of method paySalaries().

At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?
On a non-pipelined sequential processor, a program segment, which is a part of the interrupt service routine, is given to transfer 500 bytes from an I/O device to memory.     Initialize the address register     Initialize the count to 500 LOOP: Load a byte from device     Store in memory at address given by address register     Increment the address register     Decrement the count     If count! = 0 go to LOOP Assume that each statement in this program is equivalent to a machine instruction which takes one clock cycle to execute if it is a non-load/store instruction. The load-store instructions take two clock cycles to execute. The designer of the system also has an alternate approach of using the DMA controller to implement the same transfer. The DMA controller requires 20 clock cycles for initialization and other overheads. Each DMA transfer cycle takes two clock cycles to transfer one byte of data from the device to the memory. What is the approximate speedup when the DMA controller based design is used in place of the interrupt driven program based input-output?
You develop an enterprise application, called XYZApplication that includes a Windows Form presentation layer, middle-tier components for business logic and data access, and a Microsoft SQL Server database.
You are in the process of creating a middle-tier component that will execute the data access routines in your application. When data is passed to this component, the component will call several SQL Server stored procedures to perform database updates. All of these procedure calls run under the control of a single transaction.
The code for the middle-tier component will implement the following objects:
SqlConnection cn = new SqlConnection();
SqlTransaction tr;
If two users try to update the same data concurrently, inconsistencies such as phantom reads will occur. You must now add code to your component to specify the highest possible level of protection against such inconsistencies.
Which code segment should you use?
