Consider the following program public int test int result

Consider the following program:
public int test( ) {
int result = 5;
try {
   checkIt( result );
result += 5;
} catch ( ArithmeticException e ) {
result += 10;
} catch ( RuntimeException e ) {
result += 20;
} catch ( java.io.IOException e ) {
result = 0;
}
return result;
}
What value does the method \'test\' return in each of the following situations?
-The method call to \'checkIt\' returns successfully.
-The method call to \'checkIt\' generates a FileNotFoundException.
-The method call to \'checkIt\' generates an ArithmeticException.
-The method call to \'checkIt\' generates a ClassCastException.

Solution

Question 1: The method call to \'checkIt\' returns successfully.

Answer: if checkit returns successfully then test method will return value 10

Question 2: The method call to \'checkIt\' generates a FileNotFoundException.

Answer:  if checkit generates a FileNotFoundException then test method will return value 0

Becuase that exception will be handled by catch ( java.io.IOException e ) this block here we are setting result = 0. so test method will return 0.

Question 3: The method call to \'checkIt\' generates an ArithmeticException.

Answer:  if checkit generates a ArithmeticException then test method will return value 15

Becuase that exception will be handled by catch ( ArithmeticException e ) this block here we are setting result = result + 10. so test method will return 15.

Question 4: The method call to \'checkIt\' generates a ClassCastException.

Answer:  if checkit generates a ClassCastException then test method will return value 25

Becuase that exception will be handled by catch ( RuntimeException e ) this block here we are setting result = result + 20. so test method will return 25.
