Question

Given an array, write code to scan the array for a particular purpose.

Given a class, write a getter and/or a setter.

Given a class with a list, write code that manages the list.

Answer 1

Since you have not mentioned the language of your preference, I am providing the code in Java.

1.

CODE

public class Main {

public static void main(String[] args) {

int arr[] = {34, 1, 56, 8, 19};

int sum = 0;

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

sum += arr[i];

}

System.out.println("Sum of array elements = " + sum);

}

}

2.

class Person {

private String name;

private int age;

private char sec;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public char getSec() {

return sec;

}

public void setSec(char sec) {

this.sec = sec;

}

}

3.

import java.util.ArrayList;

class MyList {

private ArrayList<String> list;

public MyList() {

list = new ArrayList<>();

}

public void add(String x) {

list.add(x);

}

public void delete(String x) {

list.remove(x);

}

public boolean isEmpty() {

return list.isEmpty();

}

public void update(int i, String x) {

list.set(i, x);

}

}
