Answer:

The code to this question as follows:

Code:

if(userInput.charAt(0)==firstLetter) // if block

{

//statements

}

else //else block

{

//statements.

}

Explanation:

The description of the above code as follows:

  • In the program, we use two variables for user input that is "userInput and firstLetter". The datatype of the userInput is a string that is used to insert any value from the user. Then we use the firstLetter variable the datatype of the variable is char because it is used to detect first character. To detect this we define the conditional statement.
  • In the if block we check condition that userInput first index value is equal to firstLetter it will print "Found match: value".
  • In else block if the value does not match it will print "No match: value".
