Define a class to overload the function print as follows:
void print() - to print the following format
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
5 5 5 5
void print(int n) - To check whether the number is a lead number. A lead number is the one whose sum of even digits are equal to sum of odd digits.
e.g. 3669odd digits sum = 3 + 9 = 12even digits sum = 6 + 6 = 123669 is a lead number.
Programming Example
Define a class to overload the function print as follows:
void print() - to print the following format
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
5 5 5 5
void print(int n) - To check whether the number is a lead number. A lead number is the one whose sum of even digits are equal to sum of odd digits.
e.g. 3669
odd digits sum = 3 + 9 = 12
even digits sum = 6 + 6 = 12
3669 is a lead number.
Study this program carefully to understand the logic, output, and explanation in a structured way.
import java.util.Scanner;
public class RansariMethodOverload {
// Method to print the pattern
public void print() {
for (int i = 1; i <= 5; i++) {
for (int j = 1; j <= 4; j++) {
System.out.print(i + " ");
}
System.out.println();
}
}
// Method to check for a lead number
public void print(int n) {
int d, evenSum = 0, oddSum = 0;
while (n != 0) {
d = n % 10;
if (d % 2 == 0)
evenSum += d; // Sum of even digits
else
oddSum += d; // Sum of odd digits
n /= 10;
}
// Check if it's a lead number
if (evenSum == oddSum)
System.out.println(n + " is a Lead number");
else
System.out.println(n + " is Not a lead number");
}
public static void main(String args[]) {
RansariMethodOverload obj = new RansariMethodOverload(); // Corrected class name
Scanner in = new Scanner(System.in);
System.out.println("Pattern:");
obj.print();
System.out.print("Enter a number: ");
int num = in.nextInt();
obj.print(num);
in.close(); // Closing scanner to prevent resource leak
}
}
Pattern:
1 1 1 1
2 2 2 2
3 3 3 3
4 4 4 4
5 5 5 5
Enter a number: 3669
3669 is a Lead number
The program demonstrates method overloading in Java with two print methods:
print(): Prints a 5x4 pattern where each row contains the row number repeated 4 times.print(int n): Checks if a number is a lead number, where the sum of even digits equals the sum of odd digits.
In the main method:
- It first prints the pattern.
- Then, it checks if the user-entered number is a lead number.
The program efficiently handles digit extraction and compares the sums of even and odd digits to determine if it's a lead number.
