How to fill setter method with double[] argument in Java?

Question

public class HealthInsurancePlan {
   
   //variable for setter & getter method
      private double coverage[] = {0.0,0.0};
    
  //setter
      public void setCoverage(double coverage[]){
          this.coverage = coverage;
      }
    
  //getter
      public double[] getCoverage() {
          return coverage;
      }
}

1. No why following command doesn't work?

2. What is proper way to fill arguments in the setter method?

   setCoverage(0.1,0.2);

Thx.

Answer 1

You can use Java var args so that it accepts variable number of objects and converts it into array of objects. Update your setter as follows:

 //setter
 public void setCoverage(double... coverage){
    this.coverage = coverage;
 }

and you can just call setCoverage(0.1,0.2)
