Question 3
Define a class named StepTracker with the following specifications:
Member Variables:
String name: stores the user's name
int sw: stores the total number of steps walked by the user
double cb: stores the estimated calories burned by the user
double km: stores the estimated distance walked in kilometers
Member Methods:
void accept(): to input the name and the steps walked using Scanner class methods only
void calculate(): calculates calories burned and distance in km based on steps walked using the following estimation table:
Metric Calculation Formula
Calories Burned steps walked * 0.04 (e.g. 1 step burns 0.04 calories)
Distance (km) steps walked / 1300 (e.g. 1300 steps is approx. 1 km)
void display(): Display the calories burned, distance in km and the user's name.
Write a main() method to create an object of the class and invoke the methods.
class StepTracker{
String name;
int sw;
double cb;
double km;
public void accept(){
Scanner in = new Scanner(System.in);
System.out.print("Name: ");
name = in.nextLine();
System.out.print("Number of steps: ");
sw = in.nextInt();
}
public void calculate(){
cb = sw * 0.04;
km = sw / 1300.0;
}
public void display(){
System.out.println("Calories burned: " + cb);
System.out.println("Distance: " + km + " km");
System.out.println("Name: " + name);
}
public static void main(String[] args){
StepTracker obj = new StepTracker();
obj.accept();
obj.calculate();
obj.display();
}
}
Question 4
Write a program to accept the designations of 100 employees in a single dimensional array. Accept the designation from the user and print the total number of employees with the designation given by the user as input.
Example:
Trainee Manager Chef Manager Director Manager
Input:Manager Output: 3
class Employee{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
String d[] = new String[100];
System.out.println("Enter 100 designations:");
for(int i = 0; i < d.length; i++)
d[i] = in.nextLine();
System.out.print("Designation to be searched: ");
String s = in.nextLine();
int c = 0;
for(int i = 0; i < d.length; i++){
if(s.equalsIgnoreCase(d[i]))
c++;
}
System.out.println(c + " such employees!");
}
}
Question 5
Write a program to accept a two-dimensional integer array of order 4 ⨯ 5 as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
Example:
4 3 0 1 0
1 0 0 2 0
1 0 1 0 0
0 3 2 0 0
Number of zero elements = 11
Number of non-zero elements = 9
Matrix is a Sparse Matrix
class Sparse{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
int a[][] = new int[4][5];
int z = 0;
int nz = 0;
System.out.println("Enter 20 integers:");
for(int i = 0; i < 4; i++){
for(int j = 0; j < 5; j++){
a[i][j] = in.nextInt();
if(a[i][j] == 0)
z++;
else
nz++;
}
}
if(z > nz)
System.out.println("Sparse Matrix");
else
System.out.println("Not a Sparse Matrix");
}
}
Question 6
Write a program to accept a number and check if it is a Mark number or not. A number is said to be Mark when the sum of the squares of each digit is an even number as well as the last digit of the sum and the last digit of the number given are same.
Example: n = 246
sum = 2 ⨯ 2 + 4 ⨯ 4 + 6 ⨯ 6 = 56
56 is an even number as well as last digit is 6 for both sum as well as the number.
class Mark{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
System.out.print("Enter the integer: ");
int n = in.nextInt();
int sum = 0;
for(int i = n; i != 0; i /= 10){
int d = i % 10;
sum += d * d;
}
if(sum % 2 == 0 && sum % 10 == n % 10)
System.out.println(n + " is a Mark number!");
else
System.out.println(n + " is not a Mark number.");
}
}
Question 7
Define a class to overload the method format() as follows:
void format(): To print the following pattern using nested for loops only:
1 2 3 4 5
2 3 4 5
3 4 5
4 5
5
int format(String s): To calculate and return the sum of ASCII codes of each character of the string.
Example: CAB
Output: 67 + 65 + 66 = 198
void format(int n): To calculate and display the sum of natural numbers up to n given by the formula n(n + 1) / 2
public static void format(){
for(int i = 5; i >= 1; i--){
for(int j = i; j <= 5; j++)
System.out.print(j + " ");
System.out.println();
}
}
public static int format(String s){
int sum = 0;
for(int i = 0; i < s.length(); i++)
sum += s.charAt(i);
return sum;
}
public static void format(int n){
int sum = n * (n + 1) / 2;
System.out.println("Sum = " + sum);
}
}
Question 8
Write a program to accept a word and print the Symbolic of the accepted word. Symbolic word is formed by extracting the characters from the first consonant, then add characters before the first consonant of the accepted word and end with "TR".
Example: AIRWAYS Symbolic word is RWAYSAITR
BEAUTY Symbolic word is BEAUTYTR
class Symbolic{
public static void main(String[] args){
Scanner in = new Scanner(System.in);
System.out.print("Enter the word: ");
String w = in.next().toUpperCase();
int pos = 0;
for(int i = 0; i < w.length(); i++){
char ch = w.charAt(i);
if(Character.isLetter(ch) && "AEIOU".indexOf(ch) == -1){
pos = i;
break;
}
}
String sym = w.substring(pos) + w.substring(0, pos) + "TR";
System.out.println("Symbolic word is " + sym);
}
}
