Exception in thread "main" java.lang.NoSuchMethodException at Project1/package1.ExceptionTest10.main(ExceptionTest10.java:8) C) Compiler error D) None of the above 4) What are the difference between Checked and Unchecked exceptions in Java? A) Unchecked exceptions produce less number of compiler errors than the code with Checked exceptions. B) Most of the unchecked exceptions have RuntimeException as the superclass. Checked exceptions have different classes are superclasses. C) Unchecked exceptions cause more number of runtime exceptions at the time of execution.

A) Compiler B) Runtime C) Programmer D) None 11) What is the output of the below Java program with Try With Resource block? import java.io.*; public class ExceptionTest12 { public static void main(String[] args) { try(BufferedWriter bw = new BufferedWriter(new FileWriter("abc.txt"));) { System.out.println("Inside Try With Resource block."); } catch(Exception e) { } } } A) Inside Try With Resource block. B) No output C) Compiler error D) None of the above 12) Is it possible to write Java code efficiently without using TRY-WITH-RESOURCE blocks? A) Yes B) No C) - D) - 13) A try-with-resource supports only the objects of classes to close automatically that implement ___ Interface in Java. A) java.lang.Closeable B) java.lang.AutoCloseable C) Both A and B D) None 14) What is the output of the below Java program with nested exceptions? public class ExceptionTest14 { public static void main(String[] args) { try { int a=10/1; try {int b=20/1;} catch(Exception e1) { System.out.println("b=20"); } } catch(Exception e2) {System.out.println("a=10");} } } A) a=10 b=20 B) b=20 a=10 C) Compiler error D) No output Ad 15) Choose the right statement about nesting of try-catch-finally in Java? A) try { try{} catch(Exception e1){} finally{} } catch(Exception e2) {} B) try { try{} catch(Exception e1){} finally{} } catch(Exception e2) { try{} catch(Exception e3){} finally{} } C) try { } catch(Exception e2) { } finally { try{} catch(Exception e3){} finally{} } D) All the above 16) The variables initialized inside a TRY-with-resource are treated like ____ variables in Java.
