Lab: Static Method II

Define a Complex class with a static method for computing complex addition. Use (2+3i)*(4+5i) in your test.

public class ADT {

private int real, image ;

public ADT(){

}

public ADT(int real , int image) {

this.real = real;

this.image = image;

}

public ADT mult(ADT ADT2){

ADT ans = new ADT(0,0) ;

ans.real = this.real * ADT2.real + this.image * ADT2.image;

ans.image = this.image * ADT2.real + this.real * ADT2.image;

return ans;

}

public String toString(){

return real + "+" + image + "i";

}

}

public class StaticMethodII {

public static void main(String[] args) {

ADT f1, f2;

f1 = new ADT(2,3);

f2 = new ADT(4,5);

System.out.println("f1 = " + f1.toString());

System.out.println("f2 = " + f2.toString());

System.out.println("f1 x f2 = " + f1.mult(f2).toString());

}
