I am a new programmer in javafx. I am building a desktop application named as fuzzy calculator. whenever I run this program it opens a user interface but when click on the button(Max-Min) in the interface I found my output in the console instead of textfield. How can I get my desired output in the textfield I have created??? I have already wasted too many hours searching the solution but none of them is working or clear to me.
I am attaching my code below for your suggestion..
N.B: as my application is in developing mood all button is not working currently, only Max-min button is active.
Main.java
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
primaryStage.setTitle("Fuzzy Calculator");
primaryStage.setScene(new Scene(root, 600, 400));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Controller.java
package sample;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import java.util.Arrays;
import java.util.Scanner;
public class Controller {
@FXML
private Button add;
@FXML
private Button maxmin;
@FXML
private Button maxavg;
@FXML
private Button sub;
@FXML
private TextField display;
@FXML
private Button maxprod;
@FXML
private Button minmax;
@FXML
void maxmin(ActionEvent event) {
System.out.println("Array size:");
Scanner input=new Scanner(System.in);
int n=input.nextInt();
System.out.println("1st input ");
int a[][]=new int [n][n];
for(int i=0;i<n;i++)
{
for(int j=0;j<n;j++)
{
a[i][j]=input.nextInt();
}
}
System.out.println("2nd input ");
int b[][]=new int [n][n];
for(int i=0;i<n;i++)
{
for(int j=0;j<n;j++)
{
b[i][j]=input.nextInt();
}
}
int [] c=new int [n];
int [] k=new int [n];
int t=0;
for(int i=0;i<n;i++)
{
t=0;
for(int j=0;j<n;j++ )
{
if(a[i][j]<b[j][i])
{
k[t]=a[i][j];
t++;
}
else
{
k[t]=b[j][i];
t++;
}
}
Arrays.sort(k);
c[i]=k[n-1];
}
System.out.println("the output is :");
for(int i=0;i<n;i++)
{
System.out.print(" "+c[i]);
}
}
}
