Create two classes named Mammals and Marine Animals. Create another class named Blue Whale which inherits both the above classes. Now, create a function in each of these classes which prints "I am mammal", "I am a marine animal" and "I belong to both the categories: Mammals as well as Marine Animals" respectively. Now, create an object for each of the above class and try calling

function of Mammals by the object of Mammal

function of Blue Whale by the object of Blue Whale

function of each of its parent by the object of Blue Whale

function of Marine Animal by the object of Marine Animal

Write a program to read from “data.txt” that contains more than 1 digit of integers. Then you have to find the number which have same digits like (444, 3333, 11). You should make as many functions as you can with proper naming convention.

The following formula is used to calculate between three values:

-Distance in Kilometer, KM

- Time in Hour, H

-Speed in KM/H

Determine the car’s speed based on the related input value using the following table. using selection.

speed indicator

<=110 KM/H okay

>110 KM/H fast

Write a program that mimics a calculator . The program should take as input two integers and the operation to be performed . It should then output the numbers , the operator and the result . (For division , if the denominator is zero , output an appropriate message.) .Some sample output as follow 

3 + 4 = 7 

13 * 5 = 65

Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

Input:-

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).

Output:-

The output should be a single line containing the secret message. All characters in the output should be in lower case.

For Example -

Input 1:-

python

Output 1:-

16-25-20-8-15-14

Input 2:-

Foundations

Output 2:-

6-15-21-14-4-1-20-9-15-14-19

Input 3:-

python learning

Output 3:-

16-25-20-8-15-14 12-5-1-18-14-9-14-7

Note:- there is a space between two strings that means 16-25-20-8-15-14 12-5-1-18-14-9-14-7

We want given both three inputs they can get both three outputs we code was run one by one input and output

Suppose that you have the following declaration:

int j = 0;

The output of the statement:

if ((8 > 4) || (j++ == 7))

System.out.println("j = " + j); is:

j = 0

while the output of the statement:

if ((8 > 4) | (j++ == 7))

System.out.println("j = " + j);

is:

j = 1
