EXPERTY DESIGNED 1Z0-809 PRACTICE TEST

Given the code fragments:

Given code of Test.java file: 

1. package com.udayan.ocp;

2.  

3. import java.util.stream.Stream;

4.  

5. public class Test {

6.     public static void main(String[] args) {

7.         Stream stream = Stream.of("d", "cc", "bbb", "aaaa");

8.         stream.sorted().forEach(System.out::println);

9.     }

10. }

Which of the following needs to be done, so that output is: 

d

cc

bbb

aaaa

Assume that proper import statements are available, and 'fr' is the language code for French language. 

And you have the following code snippet:

Locale [] loc = Locale.getAvailableLocales(); 

Which of the following statements will print all the supported (by the JVM) French Language Locale on to the console?

Select 2 options.

Given code of Test.java file:

package com.udayan.ocp;

import java.util.Arrays;

import java.util.List;

public class Test {

    public static void main(String[] args) {

        List list = Arrays.asList("A", "E", "I", "O");

        list.add("U");

        list.forEach(System.out::print);

    }

}

What will be the result of compiling and executing Test class?
