Thread: Getting errors

Hi there, I'm new to this site and java programming, and this is my first given assignment. Define a class named Asset to store the details of an asset in the company. Each object of Asset should store the information. The Asset class should include a no-argument constructor, a constructor with parameters, appropriate setter and getter methods. Write a driver program that tests the various operations of the class. I get 6 errors of non-static method cannot be referenced from a static context.

import java.util.Scanner;
public class Asset{
	private String assetID;
	private String description;
	private String date;
	private int orderNum;
	private double cost;
	private String status;
 
	public Asset(){
	}
 
	public Asset(String assetID, String description, String date, int orderNum, double cost, String status){
		this.assetID = assetID;
		this.description = description;
		this.date = date;
		this.orderNum = orderNum;
		this.cost = cost;
		this.status = status;
	}
 
	public void setAssetID(String assetID){
		this.assetID = assetID;
	}
 
	public void setDescription(String description){
		this.description = description;
	}
 
	public void setDate(String date){
		this.date = date;
	}
 
	public void setOrderNum(int orderNum){
		this.orderNum = orderNum;
	}
 
	public void setCost(double cost){
		this.cost = cost;
	}
 
	public void setStatus(String status){
		this.status = status;
	}
 
	public String getAssetID(){
		return assetID;
	}
 
	public String getDescription(){
		return description;
	}
 
	public String getDate(){
		return date;
	}
 
	public int getOrderNum(){
		return orderNum;
	}
 
	public double getCost(){
		return cost;
	}
 
	public String getStatus(){
		return status;
	}
}
 
class TestAsset{
	public static void main(String [] args){
		Scanner s = new Scanner(System.in);
 
		String assetID;
		String description;
		String date;
		int orderNum;
		double cost;
		String status;
 
		System.out.print("Enter asset ID: ");
		assetID = s.next();
 
		System.out.print("Enter the description: ");
		description = s.next();
 
		System.out.print("Enter the date: ");
		date = s.next();
 
		System.out.print("Enter the order number: ");
		orderNum = s.nextInt();
 
		System.out.print("Enter the cost: ");
		cost = s.nextDouble();
 
		System.out.print("Enter the status: ");
		status = s.next();
 
		System.out.print("Asset ID: " + Asset.getAssetID());
		System.out.print("Description: " + Asset.getDescription());
		System.out.print("Date: " + Asset.getDate());
		System.out.print("Order number: " + Asset.getOrderNum());
		System.out.print("Cost: " + Asset.getCost());
		System.out.print("Status: " + Asset.getStatus());
 
	}
}

Any guideline will be appreciated.

non-static method cannot be referenced from a static context.

You need to create an object to be able to reference a class's non-static methods. The non-static members of a class do NOT exist until an object is created. static members do exist without an object.
Classname objRef = new Classname(); // create object
objRef.method(); // use non-static method

Thanks Norm, now I'm able to run the program, but now I get the error Exception in thread "main" java.util.InputMismatchException

java.util.InputMismatchException

What did you type in for the statement at line 93 to read? Was it an integer or something else?
The Scanner nextInt() method requires you enter an integer.

I get that error after I type in the input for line 87, couldn't get to the next enter input.

at java.util.Scanner.nextInt(Scanner.java:2050)
at TestAsset.main(Asset.java:93)

The error message says the error occurred in line 93 where there is a call to nextInt()
I have no idea where line 87 or line 93 are in your program.

Can you open a command prompt, execute the program and copy and paste the full contents of the screen here?

Sorry for taking too long, is this fine?

You need to read what the Scanner next() method does.
The effect on your program was that your answer to the question: Enter the description:
supplied answers for the next few questions.
Did you notice that the program did not wait for you to enter data before it asked the next question?
