According to Java naming convention we discussed in class, which of the following identifiers indicate variables?  1) FindArea 2) findArea 3) totalLength 4) TOTAL_LENGTH 5) stringGroup of answer choices1, 21, 42, 32, 3, 5

According to Java naming conventions:

1. Variables should start with a lowercase letter and follow the camelCase style.

2. Class names should start with an uppercase letter and also follow the camelCase style.

3. Constants should be in all uppercase letters with words separated by underscores.

So, based on these conventions:

1. FindArea - This follows the convention for class names, not variables.

2. findArea - This follows the convention for variables.

3. totalLength - This also follows the convention for variables.

4. TOTAL_LENGTH - This follows the convention for constants, not variables.

5. stringGroup - This follows the convention for variables.

So, the identifiers that indicate variables are: findArea, totalLength, and stringGroup. Therefore, the correct answer is 2, 3, 5.
