我的程序要写java实现类,我写了4个文件,
mycompanymain->这将显示其他文件的输出。
company->这将是company.java,其中包含公司的名称。
地址->这将包含为公司工作的人的地址。
供应商->这将链接两个类[公司,地址]。
我有这些错误:
MyCompanyMain.java:29: error: bad initializer for for-loop
for(Suppliers : company.getSuppliers())
^
1 error
Error: Could not find or load main class MyCompanyMain
Caused by: java.lang.ClassNotFoundException: MyCompanyMain
这是mycompanymain.java:
import java.util.ArrayList;
import static java.lang.System.out;
public class MyCompanyMain
{
public static void main(String[] args)
{
Company company = new Company();
company.setName("ABC sdn bhd");
Address address = new Address(123, "Jalan UTeM", "Durian Tunggal",76100, "Melaka", 06123456);
company.setAddress(address);
ArrayList<Supplier> suppliers = new ArrayList<Supplier>();
Supplier supplierBuku = new Supplier();
supplierBuku.setSupplierName("Syarikat Buku Sdn Bhd");
Address supplierBukuAddress = new Address(3, "Jalan Munsyi", "Ayer Keroh", 75400, "Melaka", 06123123);
supplierBuku.setAddress(supplierBukuAddress);
Supplier supplierComputer = new Supplier();
supplierComputer.setSupplierName("Syarikat Computer Sdn Bhd");
Address supplierComputerAddress = new Address(3, "Jalan Bukit Beruang","Ayer Keroh", 75400, "Melaka", 06111223);
supplierComputer.setAddress(supplierComputerAddress);
suppliers.add(supplierBuku);
suppliers.add(supplierComputer);
Company.setSuppliers(suppliers);
Address comp_Address = company.getAddress();
out.println(comp_Address.getNoShop()+" :"+comp_Address.getRoad()+" : "+comp_Address.getDistrict()+" :"+comp_Address.getPhone());
for(Suppliers : company.getSuppliers())
{
out.print(s.getSupplierName()+" \t: ");
Address supp_Address = s.getAddress();
out.println(supp_Address.getNoShop()+" :"+supp_Address.getRoad()+" : "+supp_Address.getDistrict()+" :"+supp_Address.getPhone());
}
}
}
这是company.java:
import java.util.* ;
public class Company {
private String name ;
private Address address ;
private ArrayList<Supplier> suppliers ;
public Company() {
suppliers = new ArrayList<Supplier>();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
public ArrayList<Supplier> getSuppliers() {
return suppliers;
}
public void setSuppliers(ArrayList<Supplier> suppliers) {
this.suppliers = suppliers;
}
}
这是address.java:
public class Address {
private int noShop ;
private String road ;
private String district ;
private int posCode ;
private String state ;
private int phone ;
public Address(int noShop, String road, String district, int posCode, String state, int phone) {
this.noShop = noShop;
this.road = road;
this.district = district;
this.posCode = posCode;
this.state = state;
this.phone = phone;
}
public int getNoShop() {
return noShop;
}
public String getRoad() {
return road;
}
public String getDistrict() {
return district;
}
public int getPosCode() {
return posCode;
}
public String getState() {
return state;
}
public int getPhone() {
return phone;
}
}
这是supplier.java:
public class Supplier {
private String supplierName ;
private Address address ;
public Supplier() {
}
public String getSupplierName() {
return supplierName;
}
public void setSupplierName(String supplierName) {
this.supplierName = supplierName;
}
public Address getAddress() {
return address;
}
public void setAddress(Address address) {
this.address = address;
}
}

这里的问题不是
main
方法,这是因为您的代码无法编译,因为您缺少增强for循环的类型声明。你好像少了一个间隔Supplier
(类型)和s
(声明的变量):au9on6nz2#
for循环中缺少一个变量,请使用
