Question 32 of 513
1Z0-829 Practice Question: Handling Date, Time, Text, Numeric and Boolean Values
What is the result of executing the following code snippet?
BigDecimal d1 = new BigDecimal("1.00"); BigDecimal d2 = new BigDecimal("1.0"); System.out.println(d1.equals(d2));
⚠ Common exam trap
Watch out — candidates often assume `equals` behaves like `compareTo` or like primitive `==` for numeric values, forgetting that `BigDecimal.equals` enforces scale equality, so `1.00` and `1.0` are not equal.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
false
The `equals` method of `BigDecimal` compares both the numeric value and the scale (number of digits after the decimal point). Since `new BigDecimal("1.00")` has a scale of 2 and `new BigDecimal("1.0")` has a scale of 1, they are not considered equal by `equals`, even though they represent the same mathematical value. Therefore, the output is `false`.
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
Why this is correct
Correct: d1.equals(d2) returns false due to scale mismatch.
- ✗
compile error
Why it's wrong here
Incorrect: The code compiles and runs without error.
- ✗
true
Why it's wrong here
Incorrect: equals() returns false because scales are different (2 vs 1).
- ✗
1
Why it's wrong here
Incorrect: The output is a boolean, not an integer.
