gaussian class in java -


i making class simulates gaussian integer. using constructor in addition method add 2 two parts of gint , return new gint sum. reason when trying implement method, java says gint required when initialize new gint , found void. why be? have included class below , indicated line causes error.

public class gint {      private int real;     private int imag;        public void gint(int r)     {         imag=0;         real=r;      }      public void gint(int r, int i)     {         real=r;         imag=i;      }      gint add(gint rhs)     {         gint added;         int nreal=this.real+rhs.real;         int nimag=this.imag+rhs.real;          added= gint(nreal,nimag);   //--> says requires gint , found void          return added;     } }

use implementation , happy:

public class gint {      private int real;     private int imag;      public gint(int r) {         imag=0;         real=r;     }      public gint(int r, int i) {         real = r;         imag = i;     }      gint add(gint rhs) {         gint added;         int nreal = this.real + rhs.real;         int nimag = this.imag + rhs.real;          added = new gint(nreal, nimag);          return added;     } }

comments:

  • don't use class names begin lowercase letter (e.g. gint instead of gint)
  • constructors in java not have return type in java, removed void type in op
  • you need new operator create new gint object in java
