Exception Handling

When does Exceptions in Java arises in code sequence?

• Run Time

• Compilation Time

• Can Occur Any Time

• None of the mentioned

Which of these keywords is not a part of exception handling?

• try

• finally

• thrown

• catch

Predict the output of following Java program

class Main {

public static void main(String args[]) {

try {

throw 10;

}

catch(int e) {

System.out.println("Got the Exception " + e);

}

}

}

• Got the Exception 10

• Got the Exception 0

• Compiler Error

class Test extends Exception { }

class Main {

public static void main(String args[]) {

try {

throw new Test();

}

catch(Test t) {

System.out.println("Got the Test Exception");

}

finally {

System.out.println("Inside finally block ");

}

}

}

• Got the Test Exception

  Inside finally block

• Got the Test Exception

• Inside finally block

• Compiler Error

Output of following Java program?

class Main {

public static void main(String args[]) {

int x = 0;

int y = 10;

int z = y/x;

}

}

• Compiler Error

• Compiles and runs fine

• Compiles fine but throws ArithmeticException exception

class Test

{

public static void main (String[] args)

{

try

{

int a = 0;

System.out.println ("a = " + a);

int b = 20 / a;

System.out.println ("b = " + b);

}

catch(ArithmeticException e)

{

System.out.println ("Divide by zero error");

}

finally

{

System.out.println ("inside the finally block");

}

}

}

• Compile error

• Divide by zero error

• a = 0

  Divide by zero error

  inside the finally block

• a = 0

• inside the finally block

Which of these is a super class of all errors and exceptions in the Java language?

• RunTimeExceptions

• Throwable

• Catchable

• None of the above

The built-in base class in Java, which is used to handle all exceptions is

• Raise

• Exception

• Error

• Throwable

Which of these keywords must be used to monitor for exceptions?

• try

• finally

• throw

• catch

Which of these keywords must be used to handle the exception thrown by try block in some rational manner?

• try

• finally

• throw

• catch
