Chapter 6, Problem 11RE

Explanation of Solution

a.

Consider the given code segment:

ArrayList<int> values = new ArrayList<int>();

Wrong in the given code segment:

In the above code segment,

• An array list named “values” has been declared with the data type “int” and it causes compiler error because array list cannot contain values of a primitive type, that is, “int”...

Explanation of Solution

b.

Consider the given code segment:

ArrayList<Integer> values = new ArrayList();

Wrong in the given code segment:

In the given code segment,

• An array list named “values” has been declared with the data type “Integer” and it causes error because in the array list, the name of the generic class is missing...

Explanation of Solution

c.

Consider the given code segment:

ArrayList<Integer> values = new ArrayList<Integer>;

Wrong in the given code segment:

In the given code segment,

• An array list named “values” has been declared with the data type “Integer” and it causes error because they did not mention parenthesis “()” after “ArrayList<Integer>” and before “;”...

Explanation of Solution

d.

Consider the given code segment:

ArrayList<Integer> values = new ArrayList<Integer>();

for (int i = 1; i <= 10; i++)

{

    values.set(i - 1, i * i);

}

Wrong in the given code segment:

• When executing the given code segment, it causes an error because in the given “for” loop, the “set” method is used to access an element from the given values in the array list...

Explanation of Solution

e.

Consider the given code segment:

ArrayList<Integer> values;

for (int i = 1; i <= 10; i++)

{

    values.add(i * i);

}

Wrong in the given code segment:

In the given code segmen...
