Solution

1) There is a complie time error in the display function, at the line:

while(i < newFlowers.length && uniqueFlower.compareTo(newFlowers[i]) == 0) {

From the above line, need to change, newFlowers[i].getName() to compare with uniqueFlower as,

while(i < newFlowers.length && uniqueFlower.compareTo(newFlowers[i].getName()) == 0) {

//Flowers.java

public class Flowers {

private String Name;

private String Color;

  

public Flowers(String Name, String Color) {

this.Name = Name;

this.Color = Color;

  

}

  

public Flowers() {

  

}

  

public String getName() {

return Name;

}

  

public void setName(String Name) {

this.Name = Name;

}

  

public String getColor() {

return Color;

}

  

public void setColor(String Color) {

this.Color = Color;

}

  

  

public String toString() {

return \" Name: \" + Name + \"\ Color: \" + Color;

}
