I am trying to display the value of percentage in a pie chart, for that I have the percentage value in the Personality
class and the Chart
Class is where I need to show it. My code structure is below:
Personality.JAVA
Tree C = gson.fromJson(profile.toString(), Tree.class);
Tree.SubTree t = C.getTree();
ArrayList<Children> mc = t.getChildren();
Children c1 = mc.get(0);
ArrayList<Children1> c2 = c1.getChildren();
Children1 obj1 = c2.get(0);
private Children1 obj1; //ERROR-ILEGAL START OF EXPRESSION
public Children1 getObj1(){
return this.obj1;
}
/** ArrayList<child2> c3 = obj1.children;
child2 obj2 = c3.get(0);
ArrayList<child3> c4 = obj2.children;
child3 obj3 = c4.get(0); **/
System.out.println(obj1.getPercentage()); //ERROR - IDENTIFIER EXPECTED
Children1.JAVA
public class Children1 {
private String category;
private String id;
private String name;
private double percentage;
private double sampling_error;
private ArrayList<Children2> children;
public Double getPercentage() {
return percentage;
}
/**
*
* @param percentage
* The percentage
*/
public void setPercentage(Double percentage) {
this.percentage = percentage;
}
}
Tree.JAVA(Not sure if this class is necessary but here it is)
public class Tree {
private SubTree tree;
@Override
public String toString() {
return "ID: " + id + "\n" + "Name: "+ "\n" + tree+ "\n" ;
}
class SubTree{
private String id;
private String name;
private ArrayList<Children> children; //Gets Arraylist from Class - Children
public ArrayList<Children> getChildren() {
return children;
}
public void setChildren(ArrayList<Children> children) {
this.children = children;
}
}
public SubTree getTree() {
return tree;
}
public void setTree() {
this.tree = tree;
}
}
CHART CLASS
private PieDataset createDataset(){
Personality m = new Personality();
// Personality.class = Personality();
DefaultPieDataset result = new DefaultPieDataset();
result.setValue("Value1",m.obj1 ); //attempted to get obj1 from Persoanlity Class
result.setValue("Linux", 10);
result.setValue("Mac", 25);
return result;
}
So overall program is - get normal paragraph convert to json then to parse to java after using java values produce graph. So in this case get percentage value obj1
to show in Chart class
.
Hope you guys understood the question and thankyou for your time :)
You have to make the Children1
object visible from the Personality
class. At the moment it looks like obj1
is just a local variable and its scope is only visible to that local method
If in Personality, you have a field Children1 obj1
then this could be set by the local method or constructor. If the scope of Children1 obj1
was public OR preferably it had a getter method, then you could read it from the Chart class
assuming that the Children1 obj1
is created in the constructor ie Personality m = new Personality();
Assuming that your Personality
class looks something like
public Personailty {
....
}
then you will to add, so that it looks like
public Personailty {
....
private Children1 obj1;
public Children1 getObj1(){
return this.obj1;
}
}
Possible solution below if you have attribute called obj1 in Personality class.
Personality Class should have:
private Children1 obj1;
public Children1 getObj1(){
return this.obj1;
}
.
Change this your Code
ArrayList<Children1> c2 = c1.getChildren();
Children1 obj1 = c2.get(0);
to
ArrayList<Children1> c2 = c1.getChildren();
this.obj1 = c2.get(0);
And on your Chart class
DefaultPieDataset result = new DefaultPieDataset();
result.setValue("Value1",m.getObj1()); //attempted to get obj1 from Persoanlity Class
