Program Plan Intro
“If…else” statement:
- The statements under the “if” block gets executed only if the “if” condition is true. Otherwise, the statements under “else” part gets executed.
- The statements inside the “if” condition or “else” condition are enclosed within the opening and closing braces.
Syntax:
//If condition
if (condition)
{
//Statements
}
//Else part
else
{
//Statements
}
“compareTo ()” method: The string class contains the method called “compareTo ()” which is used to compare two strings. This can be done inside the “if” condition.
Syntax:
//Checking if both the strings are same
if (string1.compareTo(string2)==0)
{
//Statements
}

Table 10-8 from the textbook shows part of the code. Write a program that asks the user to enter a string, and then converts that string to Morse code. Note that Morse code represents both upper and lower case letters so that both 'A' and 'a' will be converted to ".-". Input Validation.None. Instructor Notes: Note: You can use the Morse table in the book or this site (space isn't listed, but it is just mapped to a space). You will most certainly need to create two parallel arrays to map the characters to the Morse code strings.arrow_forward

- Q3) Write a program that reads a string from the keyboard and tests whether it contains a valid date. Display the date and a message that indicates whether it is valid. If it is not valid, also display a message explaining why it is not valid. The input date will have the format dd/mm/yyyy. A valid month value mm must be from 1 to 12 (January is 1). The day value dd must be from 1 to a value that is appropriate for the given month. September, April, June, and November each have 30 days. February has 28 days except for leap years when it has 29. The remaining months all have 31 days each. A leap year is any year that is divisible by 4 but not divisible by 100 unless it is also divisible by 400. Sample Input#1: Please enter a date to be checked: 05/04/2021 Sample Output#1: Your date was 05:04:2021 It is a valid date.
