Question

Given is the implementation of the class IntegeArray what we did for Assignment 5. This implementation has only one data member or attribute

private int[] arr;

If the length of the array is also added as an attribute or data member of the class as shown below, please rewrite the whole IntegerArray class implementation to reflect this new added data member of len. Complete the code given below (and submit based on the given code). No main needs to be added. Just rewrite of IntegerArray class implementation is what is needed.

public class IntegerArray {

private int[] arr;

private int len;

........

}

Here is the implementation of what we did for Assignment 5.

public class IntegerArray {

private int[] arr;

//constructor

IntegerArray(int length)

{

arr = new int [length];

}

//constructor

IntegerArray(int[] array)

{

arr = array;

}

//functions

public void printliteral()

{

System.out.print("{")

for(int k = 0 ; k < arr.length ; k++)

{

if (k>0){

System.out.print(",");

}

System.out.print(arr[k] + " ");

}

Answer 1

Here is code:

// Here is the implementation of what we did for Assignment 5.

public class IntegerArray {

private int[] arr;

private int len;

// constructor

IntegerArray(int length) {

this.arr = new int[length];

this.len = length;

}

// constructor

IntegerArray(int[] array) {

this.arr = array;

this.len = array.length;

}

// functions

public void printliteral() {

System.out.print("{");

for (int k = 0; k < this.len; k++) {

if (k > 0) {

System.out.print(", ");

}

System.out.print(this.arr[k]);

}

System.out.println("}");

}

}

Sample code to test:

public class IntegerArrayTest {

public static void main(String[] args) {

int[] array = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

IntegerArray i = new IntegerArray(array);

i.printliteral();

}

}

Output:
