📌 Information & Algorithm

Design a class to overload a function compare() as follows:

(a) void compare(int, int) — to compare two integer values and print the greater of the two integers.

(b) void compare(char, char) — to compare the numeric value of two characters and print the character with the higher numeric value.

💻 Program Code

class Overload {

    // Method to compare two integer values
    void compare(int a, int b) {
        if (a > b) {
            System.out.println(a);
        } else {
            System.out.println(b);
        }
    }

    // Method to compare the numeric values of two characters
    void compare(char a, char b) {
        if ((int) a > (int) b) {
            System.out.println(a);
        } else {
            System.out.println(b);
        }
    }

    // Method to compare the length of two strings
    void compare(String a, String b) {
        if (a.length() > b.length()) {
            System.out.println(a);
        } else {
            System.out.println(b);
        }
    }
}

📘 Explanation

Table of Variables

Variable	Type	Description
`a`	`int`	An integer value for comparison.
`b`	`int`	Another integer value for comparison.
`a`	`char`	A character for comparison based on numeric value.
`b`	`char`	Another character for comparison based on numeric value.
`a`	`String`	A string for comparison based on length.
`b`	`String`	Another string for comparison based on length.

This table summarizes the variables used in the compare() methods and their purposes.

Here's a concise explanation of each method in the Overload class:

Explanation:

void compare(int a, int b)
- Purpose: Compares two integer values and prints the greater one.
- How It Works: Uses a simple if-else statement to determine which integer is larger and prints the result.
void compare(char a, char b)
- Purpose: Compares two characters based on their numeric (ASCII) values and prints the character with the higher value.
- How It Works: Converts the characters to their ASCII values using (int) and compares them. The character with the higher value is printed.
void compare(String a, String b)
- Purpose: Compares the lengths of two strings and prints the longer one.
- How It Works: Uses the length() method to get the length of each string and compares them. The string with the greater length is printed.

These methods demonstrate function overloading by using the same method name compare() with different parameter types to perform various comparison operations.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
