err get and set methods and scanner class / JOptionPane

[Abhradeep Banerjee]

Hi,

I just want to know how i am able to access the private attribute eg Private String name.

I would then want the user to key in his name using scanner class or JOptionPane.

Do i use a get and set method or?

Hi,

private access is only accessible to the class that contains the private member/attributes.
So this means you cannot directly access em.

however you may access it via public accessors. (Getters)

public class ClassA {
	private String name;
	
	public String getName() {
		return name;
	}
}

if you need to get the name use .getName() function.

thanks for your reply ryan

yes i did that part but im not sure what to put for the get method i pasted my code here


public class Customer{

private String name;
private String icNo;

public void setName(String n){
n=name;

}



public void setName(String i){
i=icNo;

}

}


import java.util.Scanner;
public class topmethod{

public static void main(String args[]){

Customer d = new Customer();
Scanner input = new Scanner(System.in);

System.out.println("Please Enter your name");
d.setName = input.nextLine();

//System.out.println("Please Enter your IC");
//d.icNo = input.nextLine();




}

}

thanks

1. no need to write two separate setter methods, you can use the one method with two arguments.
2. The way you are calling setter method is wrong. It should be

d.setName(input.nextLine()); 

3. in get method, normally, we return the value as

public String getName(){
return name;
}

ooo thanks man

[Ryan Webb]

public class Customer{

	private String name;
	private String icNo;

	public void setName(String n){
		n=name;
	}
	
	public void setName(String i){ //I think you mean setIcNo(String i) here
		i=icNo;
	}
	
	//here's where you need to put accessors :)
	public String getName() {
		return name
	}
	
	public String getIcNo() {
		return icNo;
	}
}
	
	
import java.util.Scanner;
public class topmethod{

	public static void main(String args[]){
	
		Customer d = new Customer();
		Scanner input = new Scanner(System.in);
		
		System.out.println("Please Enter your name");
		d.setName = input.nextLine();
		
		//System.out.println("Please Enter your IC");
		//d.icNo = input.nextLine();
		
		//to access do it like this :0
		String name = d.getName();
		String icNo = d.getIcNo();
		System.out.println(name);
		System.out.println(icNo);
	}

}

Please avoid screenshots; they are much harder to read than copy-and-paste.

err looks fine if you click on the download button

anyone knows the problem???

[Abhradeep Banerjee]

ok i managed to solve the problem thanks those who helped

but i got another problem how do retrive info i stored in an array.. from another class

Database.java

public class Database{


private String CarList[] = { "Altis", "Vios", "Latio", "Murano", "Jazz", "Civic", "Stream", "Odyssey", "WRX", "Impressa" };




public String findCarByModel(){

private String make;
private String model;
private int deposit;
private int rate;

//public static int calculateCost(int x) {

//return int;


//}

public void setMake(String m){

m=make;

}

public String getMake(){

Database myDatabase = new Database();



return make;
}

}


mainmethod.java
import java.util.Scanner;
public class mainmethod{

public static void main(String args[]){

Car myCar = new Car();

Scanner input = new Scanner(System.in);
System.out.print("Enter the model to rent: ");

myCar.setMake(input.nextLine());

String make = myCar.getMake();

if(make == null){
System.out.print("Model not is available");
}


}

}

Please use a new thread for a new question. Please go back to your code and add code tags with the edit button; it is very difficult to read otherwise.
