Given code of Test.java file: 1. package com.udayan.ocp;2.  3. import java.util.*;4.  5. public class Test {6.     public static void main(String[] args) {7.         NavigableMap map = new TreeMap();8.         map.put(25, "Pune");9.         map.put(32, "Mumbai");10.         map.put(11, "Sri Nagar");11.         map.put(39, "Chennai");12.  13.         System.out.println(map.headMap(25, true));14.     }15. }

Consider the code of Test.java file:1. package com.udayan.ocp;2.  3. class Player {4.     String name;5.     int age;6.  7.     Player() {8.         this.name = "Yuvraj";9.         this.age = 36;10.     }11.  12.     public String toString() {13.         return name + ", " + age;14.     }15.     16.     public Class getClass() { 17.         return super.getClass();18.     }19. }20.  21. public class Test {22.     public static void main(String[] args) {23.         System.out.println(new Player());24.     }25. }What will be the result of compiling and executing Test class?

Given the code fragment:Stream files = Files.list(Paths.get(System.getProperty(“user.home”))); files.forEach (fName -> { //line n1 try { Path aPath = fName.toAbsolutePath(); //line n2 System.out.println(fName + “:” + Files.readAttributes(aPath,Basic.File.Attributes.class).creationTime()); } catch (IOException ex) { ex.printStackTrace(); });What is the result?

Given code of Test.java file: 1. package com.udayan.ocp;2.  3. public class Test {4.     private static void div(int i, int j) {5.         try {6.             System.out.println(i / j);7.         } catch(ArithmeticException e) {8.             throw (RuntimeException)e;9.         }10.     }11.     public static void main(String[] args) {12.         try {13.             div(5, 0);14.         } catch(ArithmeticException e) {15.             System.out.println("AE");16.         } catch(RuntimeException e) {17.             System.out.println("RE");18.         }19.     }20. }What will be the result of compiling and executing Test class?

The last statement inside main(String []) method, increments value of i, which means it is not effectively final and hence compilation error.//Test.javapackage com.udayan.ocp; class Player {    String name;    int age;    Player() {        this.name = "Virat";        this.age = 29;    }        public int hashCode() {        return 100;    }} public class Test {    public static void main(String[] args) {        System.out.println(new Player());    }}Hexadecimal representation of 100 is 64.Which of the following option is correct?
