6.11 What would be the result of attempting to compile and run the following code?

public class Test {
public static void main(String[] args) {
double[] x = new double[]{1, 2, 3};
System.out.println("Value is " + x[1]);
}
}

A. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by {1, 2, 3}.
B. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by new double[3]{1, 2, 3};
C. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by new double[]{1.0, 2.0, 3.0};
D. The program compiles and runs fine and the output "Value is 1.0" is printed.
E. The program compiles and runs fine and the output "Value is 2.0" is printed.

6.26 The __________ method copies the sourceArray to the targetArray.

A. System.copyArrays(sourceArray, 0, targetArray, 0, sourceArray.length);
B. System.copyarrays(sourceArray, 0, targetArray, 0, sourceArray.length);
C. System.arrayCopy(sourceArray, 0, targetArray, 0, sourceArray.length);
D. System.arraycopy(sourceArray, 0, targetArray, 0, sourceArray.length);

6.38 Which of the following statements are correct to invoke the printMax method in Listing 6.5 in the textbook?

A. printMax(1, 2, 2, 1, 4);
B. printMax(new double[]{1, 2, 3});
C. printMax(1.0, 2.0, 2.0, 1.0, 4.0);
D. printMax(new int[]{1, 2, 3});

Section 6.11 Sorting Arrays
6.41 Use the selectionSort method presented in this section to answer this question. Assume list is {3.1, 3.1, 2.5, 6.4, 2.1}, what is the content of list after the first iteration of the outer loop in the method?

A. 3.1, 3.1, 2.5, 6.4, 2.1
B. 2.5, 3.1, 3.1, 6.4, 2.1
C. 2.1, 2.5, 3.1, 3.1, 6.4
D. 3.1, 3.1, 2.5, 2.1, 6.4
E. 2.1, 3.1, 2.5, 6.4, 3.1

6.42 Use the selectionSort method presented in this section to answer this question. What is list1 after executing the following statements?

double[] list1 = {3.1, 3.1, 2.5, 6.4};
selectionSort(list1);

A. list1 is 3.1, 3.1, 2.5, 6.4
B. list1 is 2.5 3.1, 3.1, 6.4
C. list1 is 6.4, 3.1, 3.1, 2.5
D. list1 is 3.1, 2.5, 3.1, 6.4

6.46 Assume int[] list1 = {3, 4, 1, 9, 13}, int[] list2 = {3, 4, 1, 9, 13}, and int[] list3 = {4, 3, 1, 9, 13}, what is

System.out.println(java.util.Arrays.equals(list1, list2)
+ " " + java.util.Arrays.equals(list1, list3));

A. true true
B. true false
C. false true
D. false fasle
