Question 2 If I wanted to iterate through a basic Java array, how would I do it? Would I use the "length" property or the "size()" method? For basic arrays, use the "length" property. int[] array (1, 2, 3, 4, 5}; for(int i = 0; i < array.length; i++) { System.out.println(array[i]); } For basic arrays, use the ".size()" method. int[] array (1, 2, 3, 4, 5}; for(int i = 0; i <array.size(); i++) { System.out.println(array[1]); } 1 pts E Ensign Homepage Quiz: 8.3 Quiz (30 min.) + ← → C⭑ ensign.instructure.com/courses/14050/quizzes/186729/take LDS FAFSA Student Loan ck Credit Karma M Gmail iCloud byu chat page TestOut LabSim Course Hero 2022 Fall Semester Home Announcements 38 Syllabus Modules Grades People Tutoring Resources Question 3 1 pts If I wanted to iterate through Java's ArrayList, how would I do it?
