Java program to create a set of Complex numbers using HashSet collections
Given a HashSet collection, we have to create a set of Complex numbers using it.
Submitted by Nidhi, on May 12, 2022
Problem Solution:
In this program, we will create a Complex class that contains data members real, and imaginary. Then we will add objects of the Complex class to the HashSet collection. After that, we will print complex numbers.
Program/Source Code:
The source code to create a set of Complex numbers using HashSet collections is given below. The given program is compiled and executed successfully.
// Java program to create a set of Complex numbers
// using HashSet collections
import java.util.*;
class Complex {
int real;
int imaginary;
Complex(int r, int i) {
this.real = r;
this.imaginary = i;
}
void printComplex() {
System.out.println("Complex Number: " + real + " + " + imaginary + "i");
}
}
public class Main {
public static void main(String[] args) {
HashSet < Complex > comp = new HashSet();
comp.add(new Complex(10, 20));
comp.add(new Complex(20, 30));
comp.add(new Complex(30, 40));
comp.add(new Complex(40, 50));
System.out.println("Hash Set of Complex numbers: ");
for (Complex c: comp) {
c.printComplex();
}
}
}
Output:
Hash Set of Complex numbers:
Complex Number: 10 + 20i
Complex Number: 40 + 50i
Complex Number: 30 + 40i
Complex Number: 20 + 30i
Explanation:
In the above program, we imported the "java.util.*" package to use the HashSet collection. Here, we created a public class Main and a Complex class. The Complex class contains data members real, and imaginary. The Main class contains a method main().
The main() method is the entry point for the program. Here, we created a set to store complex numbers using the HashSet collection. Then we added complex numbers to created set using add() method. After that, we printed the set elements.
