1Z0-811 Primitives, Strings and Operators Practice Question
This 1Z0-811 practice question tests your understanding of primitives, strings and operators. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Exhibit
public class Test {
public static void main(String[] args) {
String s1 = "Java";
String s2 = new String("Java");
String s3 = "Java";
System.out.println(s1 == s2);
System.out.println(s1.equals(s2));
System.out.println(s1 == s3);
}
}
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
false true true
The code uses `String.equals()` to compare the content of strings, which returns `true` for `"Java"` and `"Java"` (first comparison). The second comparison uses `==` to compare string references; since `str1` and `str2` are separate `String` objects created with `new`, they have different memory addresses, so `==` returns `false`. The third comparison uses `String.equals()` again, comparing `"Java"` (a string literal from the pool) with `str2` (a `new String` object), but the content is the same, so it returns `true`. Thus the output is `false true true`.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
false true false
Why it's wrong here
s1==s3 is true, not false
✗
true false true
Why it's wrong here
s1==s2 compares references, they are different objects
✗
true true true
Why it's wrong here
s1==s2 is false
✓
false true true
Why this is correct
s1==s2 false, equals true, s1==s3 true

Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the distinction between `==` (reference equality) and `.equals()` (value equality) for `String` objects, trapping candidates who assume `==` compares string content.
Detailed technical explanation
How to think about this question
In Java, `String` literals are interned and stored in the string constant pool, so `==` between two literals with the same content returns `true`. However, `new String("Java")` explicitly creates a new object on the heap, bypassing the pool, so `==` compares references and returns `false` even if the content is identical. The `equals()` method, inherited from `Object` and overridden in `String`, compares the actual character sequence, making it the correct way to test string equality in most cases.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 1Z0-811 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
