我收到了错误 [英] I'm getting the error

问题描述

（编译错误Main.java:69：错误：找不到符号shipmentEntity [k] .display（）; ^符号：方法display（）location：class ShipmentEntity 1 error）以下程序..



我尝试过：

(Compilation Errors Main.java:69: error: cannot find symbol shipmentEntity[k].display(); ^ symbol: method display() location: class ShipmentEntity 1 error) for the below program..

What I have tried:

ShipmentEntity.java
  public class ShipmentEntity {
protected String shipmentEntityName;
protected String identificationNumber;
ShipmentEntity()
{
    
}

public ShipmentEntity(String shipmentEntityName, String identificationNumber) {
    super();
    this.shipmentEntityName = shipmentEntityName;
	this.identificationNumber = identificationNumber;
}
public String getShipmentEntityName() {
	return shipmentEntityName;
}
public void setShipmentEntityName(String shipmentEntityName) {
	this.shipmentEntityName = shipmentEntityName;
}
public String getIdentificationNumber() {
	return identificationNumber;
}
public void setIdentificationNumber(String identificationNumber) {
	this.identificationNumber = identificationNumber;
}

你的代码确实有一个

Your code does have a

shipmentEntity[k].display();

。

We can't help you if you don't give correct information.

这是船舶实体

This is Ship Entity

ShipmentEntity.java
  public class ShipmentEntity {
protected String shipmentEntityName;
protected String identificationNumber;
ShipmentEntity()
{
    
}

public ShipmentEntity(String shipmentEntityName, String identificationNumber) {
    super();
    this.shipmentEntityName = shipmentEntityName;
	this.identificationNumber = identificationNumber;
}
public String getShipmentEntityName() {
	return shipmentEntityName;
}
public void setShipmentEntityName(String shipmentEntityName) {
	this.shipmentEntityName = shipmentEntityName;
}
public String getIdentificationNumber() {
	return identificationNumber;
}
public void setIdentificationNumber(String identificationNumber) {
	this.identificationNumber = identificationNumber;
}





}
