Error message "java.lang.NoSuchMethodError: Customer.<init>(Ljava/lang/String;D)V " [closed]

Question

I keep getting the same error message when running this program. This is what i get:

Exception in thread "main" java.lang.NoSuchMethodError: Customer.<init>(Ljava/lang/String;D)V 
at Customer5.input(Customer5.java:35)<b>---(See below (code) to refer to lines 35 & 7)
at Customer5.main(Customer5.java:7)

Another thing is that the class "Customer" shows a message that says "The type Customer is already defined."

import java.util.*;
public class Customer5 {

    public static void main(String[] args) {


        Customer[] customers=input();//This is line 7
        customers=sort(customers);
        output(customers);
    }


    public static Customer[] input(){

        Scanner input =new Scanner(System.in);
        int n;


        String name;
        double debt;


        System.out.print("Enter number of customers :");
        n=input.nextInt();

        Customer[] customers=new Customer[n];
        for(int i=0; i<n; i++){

            System.out.print("Enter name:");
            name=input.next();

            System.out.print("Enter debt:");
            debt=input.nextDouble();

            customers[i]=new Customer(name, debt);//This is line 35
        }
        return customers;
    }


    public static Customer[] sort(Customer[] customers){

        Customer temp;
        for(int i=0; i<customers.length; i++){

             for(int j=i+1; j<customers.length; j++){

                   if(customers[j-1].debt>customers[j].debt){

                         temp=customers[j-1];
                         customers[j-1]=customers[j];
                         customers[j]=temp;
                   }
             }
        }
              return customers;
    }



     public static void output(Customer[] customers){
            for(int i=0; i<customers.length; i++){
             System.out.println(customers[i].name+"\t" +customers[i].debt);
            }
     }



} 

class Customer{ //this line shows a message that says:The type Customer is already defined

    public String name;
    public Double debt;

    public Customer(String name, double debt){
       this.name=name;
       this.debt=debt;
    }

}

I don't know what to do in order to fix it. I am not very familiar with this type of error message. I'd really appreciate any feedback or comments on how to approach this problem. Thanks!

Answer 1

This Class runs fine for me, issue is there must be some other Customer class in your package or application which doesnt have constructor public Customer(String name, double debt) .

Try clicking Ctrl + Shift + R and search Customer or Press Ctrl + H, search Customer in all java files

Answer 2

Tested, it works fine for me.

Find "clear and build" option in your IDE, it should do the trick.

Also make sure, that in your project does not exist other Customer class.
