Final answer:
The code modifies an integer array using java.util.Arrays.fill(list), prints the modified and original arrays using System.out.println, and checks for equality using java.util.Arrays.equals(list1, list2). The output will show the modified array [7, 7, 7, 7], the original array [2, 4, 7, 10], and false for the equality check.
Step-by-step explanation:
The student has provided Java code and is asking for the output of this code. The code uses the java.util.Arrays.fill(list) method to modify the contents of an array, followed by the System.out.println method to print the array to the console. The java.util.Arrays.equals(list1, list2) method is then used to compare two arrays and print the result of the comparison.
Initially, an array list1 is declared with the values {2, 4, 7, 10}. The Arrays.fill() method is called on list1 to fill all of its elements with the value 7. Consequently, list1 will become {7, 7, 7, 7}. The array is then printed using Arrays.toString(), resulting in "[7, 7, 7, 7]" being displayed.
A second array list2 is declared with the original values {2, 4, 7, 10} and is printed using Arrays.toString(). Therefore, the output will be "[2, 4, 7, 10]". Finally, the code snippet calls Arrays.equals() to check if list1 and list2 are identical, which will return false since their contents are different after the fill() operation on list1.
