我分配了一份简历，以便用户输入并显示它。但是，我不知道如何调用另一个变量来实现打印/显示功能。
代码如下：
import java.util.Scanner;
public class curriculumVitae1{
public static String firstName;
public static String middleName, lastName, birthDate, maritalStatus, homeAddress, provincialAddress, mobileNumber, anotherMobile, landlineNumber, anotherLandline, primaryYears;
private static void main (String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nCurriculum Vitae");
System.out.print("\nInput your last name: ");
String lastName;
lastName = input.nextLine();
System.out.print("\nInput your first name: ");
String firstName;
firstName = input.nextLine();
System.out.print("\nInput your middle name: ");
String middleName;
middleName = input.nextLine();
System.out.print("\nInput your birthdate: ");
String birthDate;
birthDate = input.nextLine();
System.out.print("\nInput your marital status (Married, Widowed, Separated, Divorced, Single) : ");
String maritalStatus;
maritalStatus = input.nextLine();
System.out.print("\nInput your home address: ");
String homeAddress;
homeAddress = input.nextLine();
curriculumVitae1.cv();
}
private static void provincial(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nDo you have a provincial address? Enter Y if yes, and N if no: ");
char provincialQuestion;
provincialQuestion = input.nextLine().charAt(0);
if (provincialQuestion=='Y'){
System.out.print("\nInput your provincial address: ");
String provincialAddress;
provincialAddress = input.nextLine();
}
else if(provincialQuestion=='N'){
}
}
private static void mobile(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nContact Details ");
System.out.print("\nInput your mobile number: ");
String mobileNumber;
mobileNumber = input.nextLine();
System.out.print("\nDo you have another mobile number? Enter Y if yes, and N if no: ");
char mobileQuestion;
mobileQuestion = input.nextLine().charAt(0);
if (mobileQuestion=='Y'){
System.out.print("\nInput another mobile number: ");
String anotherMobile;
anotherMobile = input.nextLine();
}
else if(mobileQuestion=='N'){
}
}
private static void landline(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nInput your landline number: ");
String landlineNumber;
landlineNumber = input.nextLine();
System.out.print("\nDo you have another landline number? Enter Y if yes, and N if no: ");
char landlineQuestion;
landlineQuestion = input.nextLine().charAt(0);
if (landlineQuestion=='Y'){
System.out.print("\nInput another mobile number: ");
String anotherLandline;
anotherLandline = input.nextLine();
}
else if (landlineQuestion=='N'){
}
}
private static String email(){
Scanner input = new Scanner(System.in);
System.out.print("\nInput your email address: ");
String emailAddress;
emailAddress = input.nextLine();
return emailAddress;
}
private static String tertiary(){
Scanner input = new Scanner(System.in);
System.out.print("\nEducation History ");
System.out.print("\nTertiary Education ");
System.out.print("\nInput your tertiary education course: ");
String tertiaryCourse;
tertiaryCourse = input.nextLine();
System.out.print("\nInput your tertiary education school: ");
String tertiarySchool;
tertiarySchool = input.nextLine();
System.out.print("\nInput your tertiary education inclusive years (xxxx-xxxx): ");
String tertiaryYears;
tertiaryYears = input.nextLine();
System.out.print("\nDo you have any honors/achivements received during your tertiary education? Enter Y if yes, and N if no: ");
char tertiaryQuestion;
tertiaryQuestion = input.nextLine().charAt(0);
if (tertiaryQuestion=='Y'){
System.out.print("\nInput your honor/s or achivement/s:");
String tertiaryAchievements;
tertiaryAchievements = input.nextLine();
return tertiaryAchievements;
}
else if (tertiaryQuestion=='N'){
return "------";
}
}
private static void secondary(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nSecondary Education ");
System.out.print("\nInput your secondary education school: ");
String secondarySchool;
secondarySchool = input.nextLine();
System.out.print("\nInput your secondary education inclusive years (xxxx-xxxx): ");
String secondaryYears;
secondaryYears = input.nextLine();
System.out.print("\nDo you have any honors/achivements received during your secondary education? Enter Y if yes, and N if no: ");
char secondaryQuestion;
secondaryQuestion = input.nextLine().charAt(0);
if (secondaryQuestion=='Y'){
System.out.print("\nInput your honor/s or achivement/s:");
String secondaryAchievements;
secondaryAchievements = input.nextLine();
}
else if (secondaryQuestion=='N'){
}
}
public static void primary(String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nPrimary Education ");
System.out.print("\nInput your primary education school: ");
String primarySchool;
primarySchool = input.nextLine();
System.out.print("\nInput your primary education inclusive years (xxxx-xxxx): ");
String primaryYears;
primaryYears = input.nextLine();
System.out.print("\nDo you have any honors/achivements received during your primary education? Enter Y if yes, and N if no: ");
char primaryQuestion;
primaryQuestion = input.nextLine().charAt(0);
if (primaryQuestion=='Y'){
System.out.print("\nInput your honor/s or achivement/s:");
String primaryAchievements;
primaryAchievements = input.nextLine();
}
else{
System.out.print("------");
}
}
public static void cv(String args[]){
System.out.println(" Curriculum Vitae");
System.out.print("\nName:" + firstName + " " + middleName + " "+ lastName);
System.out.print("\nBirthdate:" + birthDate);
System.out.print("\nMarital Status:" + maritalStatus);
System.out.print("\nHome Address:" + homeAddress);
System.out.print("\nProvincial Address:" + provincialAddress);
System.out.print("\nMobile Number:" + mobileNumber );
System.out.print("\nAnother Mobile Number:" + anotherMobile);
System.out.print("\nLandline:" + landlineNumber);
System.out.print("\nYear: " + primaryYears);
}
}
但是，我总是得到这样的错误
C:\Users\BEST\Desktop\wew>javac curriculumVitae1.java
curriculumVitae1.java:33: error: method cv in class curriculumVitae1 cannot be applied to given types;
curriculumVitae1.cv();
^
required: String[]
found: no arguments
reason: actual and formal argument lists differ in length
1 error
请帮助我如何从其他函数中打印出另一个变量。或我可以做的一些选择。

您的方法期望使用(String[] args)，但是由于您不使用它们，因此我将其删除。试试
public static void cv() {
答案 1 :(得分：0)
错误详细信息突出显示您正在调用方法而未在方法签名public static void cv(String args[])中提供必需的参数：
必填部分告诉您期望的参数类型，此处String[]和 found 部分告诉您所看到的参数，此处它没有看到您传递任何参数。
原因告诉您，实际（提供的参数）数量与期望的形式（参数签名定义的形式）数量不同，即数量不足或过多提供了论据。
您也可以从原始错误消息中获得此信息：
error: method cv in class curriculumVitae1 cannot be applied to given types;
curriculumVitae1.cv();
它没有明确声明，但是从下面显示的代码行中，您可以看到“给定类型”一无是处，因为该方法的调用没有参数-括号内没有任何内容。
就像彼得·劳里（Peter Lawrey）所说，您可以从方法签名中删除String args[]，因为您不使用它。
希望这可以帮助您了解错误消息以及它们告诉您的问题更好！

对程序进行以下更改：
将main（）方法的访问说明符从私有更改为公共。否则，代码将引发错误-Does not contain a main method
由于已将firstName，middleName，lastName，birthDate等声明为静态变量，因此请勿在{{1}}中将它们声明为局部变量。将值分配给main（）方法中已经声明的静态变量，如下所示：
main method由于未使用public static void main (String args[]){
Scanner input = new Scanner(System.in);
System.out.print("\nCurriculum Vitae");
System.out.print("\nInput your last name: ");
//String lastName;
lastName = input.nextLine();
System.out.print("\nInput your first name: ");
//String firstName;
firstName = input.nextLine();
System.out.print("\nInput your middle name: ");
//String middleName;
middleName = input.nextLine();
System.out.print("\nInput your birthdate: ");
//String birthDate;
birthDate = input.nextLine();
System.out.print("\nInput your marital status (Married, Widowed, Separated,
Divorced, Single) : ");
//String maritalStatus;
maritalStatus = input.nextLine();
System.out.print("\nInput your home address: ");
//String homeAddress;
homeAddress = input.nextLine();
//System.out.println();
cv();
}
方法中的String[] args自变量。
由于cv()是cv()，因此可以直接从static method调用它。
main()变量，然后按如下所示返回它来完成此操作： tertiaryAchievements
