I want to take the Java Foundations 1Z0-811 Exam

[Numair Kaukab]

Hello, I have worked with Java Before...but I have forgotten some concepts...I am starting again...I want to be certified...I want to start with the Foundations exam..But, I can't find any resources (books, mock exams etc) anywhere..Oracle Academy has a 90 hour course...which I think is un-necessary...The exam is very basic.

Any help would be appreciated

Welcome to the Ranch

I would suggest you write some basic programs before you try sitting the exam. You should be up to speed before you learn the sometimes strange things they ask in cert exams.

I have worked with Java before..it would take 1 day of revision to get up to speed...my Question was how do I prepare...when I can't find any study guides..

So you could understand code like this?/* Where s has been declared and initialised as a String already */ System.out.println(s.chars()                    .mapToObj(i -> Character.valueOf((char)i)                    .filter(c -> !Character.isVowel(c))                    .map(String::valueOf)                    .collect(collectors.joining()));Moving to our foundation exam forum.

I can understand the code I posted, but it contains several errors

Somewhat...I dont know exactly what each function does..and, I personally think this is too advanced for the foundations exam..I might be wrong, but since there are no mock papers available..I can't really say

What does it say about Streams in the exam syllabus?

So, I found some mock exams at enthuware...but still no study guide or anything...

looks pretty basic

[Campbell Ritchie]

Careful: Oracle exams are usually harder than they look at first sight. You are right that it doesn't seem to test Stream knowledge, even though it says it was validated for JDK 1.8 (sic).
You should be able to find such information in any Java® programming book, but I don't know about mock exams, nor did I find any specimen questions.

I am having difficulty with this part of the syllabus

How will this part be tested in a Multiple-Choice Question Format

[Campbell Ritchie]

A few ideas off the top of my head.

Java® is commonly used for

1: Websites

2: Mobile phone applications

3: Connecting web apps to databases

4: direct access to memory locations

5: Multi-threaded applications

All the following were written by students as constructors: they all compiled without errors. Each class has two fields i and s. Which of these code snippets represent correct constructors that will execute correctly and not produce nasty surprises as any code is executed?

/* No 1 */
public void Deception(int i, String s)
{
   this.i = i;
   this.s = s;
}
/* No 2 */
public Reception(int i, String s)
{
   this.i = i;
   this.s = s;
}
/* No 3 */
public Perception(int i, String s)
{
   i = i;
   s = s;
}
/* No 4 */
public Exception(int i, String s)
{
   this.i = i;
   this.s = s;
}
/* No 5 */
public Dejection(int i, String s)
{
   i = this.i;
   s = this.s;
}

Which of the following fields show the correct naming and declaration conventions?

1: final static public int BOILING_WATER = 100;

2: private static final String NAME = "Numair Kaukab";

3: String name;

4: String Name;

5: private String Name;

Which of the following instructions will cause an application to run in Java8, assuming it has not yet been compiled and the class Foo has a main method?

1: java Foo.java

2: javac Foo.java java Foo.java

3: javac Foo.java java Foo "Numair Kaukab"

4: java Foo.java javac Foo.java

5: javac Foo java Foo.java

Which of the following are headings for methods that can be run to start an application off?

1: public static int main(String[] args)...

2: public static void main(String... args)...

3: public static void main(final String[] args)...

4: static void main(String[] args)...

5: public static void Main(String[] args)...

What new files would you expect to find if the instruction javac Foo.java has run for the first time without errors?

1: A file called Foo containing bytecode

2: A file called Foo.java containing machine code

3: A file called Foo.class containing bytecode

4: A file called Foo.class containing Java® code

5: A file called Foo.class containing machine code

6: No new files

Thank you. This is very helpful. I also checked out the Mock exams..I have a clear idea now..what to expect from the exam.

Can you recommend a book that can prepare me for this exam? I dont want a beginners guide..teaching me what a variable is or what a loop is. I am looking at Java in a Nutshell 7th Edition

https://www.amazon.com/Java-Nutshell-Desktop-Quick-Reference/dp/1492037257/ref=sr_1_1?crid=3K3RPWES1J9FD&dchild=1&keywords=java+in+a+nutshell&qid=1603818953&sprefix=java+in%2Caps%2C452&sr=8-1

Do you think this would be good for me?

[Campbell Ritchie]

Don't know about books, but I didn't like that book the few times I have used it.

The streams example is way too hard for the Foundations exam. Objectives here

We wrote a web page on the Java Foundations exam. You can use our Java 8 OCA (808) study guide for most of it. There are a few topics on the Foundations exam not on the OCA 8. For those we wrote blog posts (and sample questions) linked to from that page.
