Sure, let's solve this step-by-step.
1. Class Definition and Initialization: We will define a class that can handle the comparison of two strings. When initializing the class, we will convert both strings to uppercase to ensure case-insensitive comparison.
2. Method to Check Equality: We will define a method within the class to check if the two strings are equal.
3. Method to Find Longer String: We will define another method to determine which string is longer. If both strings have equal lengths, we will print a message stating this.
Here’s the step-by-step breakdown:
### Step 1: Define the Class
We will define a class named `StringComparator`. This class will have an initialization method, which will take two strings as input and convert them to uppercase.
### Step 2: Initialization Method
This method will be called `__init__`. It will accept two strings as parameters and convert them to uppercase using the `upper()` method.
### Step 3: Method to Check Equality
We will define a method named `are_equal` that compares the two strings and returns `True` if they are equal and `False` otherwise.
### Step 4: Method to Find the Longer String
This method will be named `longer_string`. It will compare the lengths of the two strings and return the string with the greater length. If the strings are of equal length, it will return the message "Both strings are of equal length."
### Step 5: Example Usage
We will create an example to demonstrate the class's functionality by comparing the strings "Hello" and "hello".
Here’s how the complete class and example usage might look:
```python
# Define the class
class StringComparator:
def __init__(self, string1, string2):
# Convert both strings to uppercase
self.string1 = string1.upper()
self.string2 = string2.upper()
def are_equal(self):
# Check if the two strings are equal
return self.string1 == self.string2
def longer_string(self):
# Determine the longer string
if len(self.string1) > len(self.string2):
return self.string1
elif len(self.string1) < len(self.string2):
return self.string2
else:
return "Both strings are of equal length."
# Example strings
string1 = "Hello"
string2 = "hello"
# Create an instance of StringComparator
comparator = StringComparator(string1, string2)
# Check if strings are equal
strings_equal = comparator.are_equal()
# Find the longer string
longer_str = comparator.longer_string()
# Result
print(strings_equal, longer_str)
```
### Result:
The output after running this example:
1. Whether the strings are equal: `True`
2. Which string is longer: `'Both strings are of equal length.'`
So, the detailed solution ensures that the strings are compared in a case-insensitive manner and identifies which string is longer or confirms if they are of equal length.
