Test.java source code:
import java.text.NumberFormat;

public class Test{
// Main method
        public static void main(String args[]) {
                Test test=new Test(0);
                double x[] = { 6.0,0.0 };
                for(int i=0;i<x.length;i++) test.formatNum(x[i]);
                System.exit(0);
        }

// Test class
        public NumberFormat numberFormat;
        public int numfracdigits;

        public Test(int numfracdigits){
                this.numfracdigits = numfracdigits;
                numberFormat = NumberFormat.getInstance() ;
    numberFormat.setMinimumFractionDigits(this.numfracdigits);
    numberFormat.setMaximumFractionDigits(this.numfracdigits);
        };

  public void formatNum(double num) {
// Uncommenting these lines gives valid result
// numberFormat = NumberFormat.getInstance();
// numberFormat.setMinimumFractionDigits(numfracdigits);
// numberFormat.setMaximumFractionDigits(numfracdigits);
                String outnum = numberFormat.format(num);
                System.out.println("Number:"+num+" Formatted:"+outnum);
  }

}

P.3 This is output:

Number:6.0 Formatted:6
