如何从第一种方法获得输入的结果？

** I have trouble getting the result from the first user. The plan is to greet both of them but I can't seem to get the value of the other method I'm using. The goal is to use overloading and to greet the both of them now I just have a problem on greeting the both of the user. I mean greet them together **

Answer 1

I am not sure if I am understanding the question correctly. Do you want to greet both of the users towards the end?

Then you'll need to set up a global variable.

import java.util.*;
public class OverloadingFG2 {

public static String fullName1;

public static void main(String[] args) {

    userenter();
    userenter(false);
}
public static void userenter(){
    Scanner input = new Scanner(System.in);
    System.out.println("Enter your Fullname: ");
    fullName1 = input.nextLine();

    System.out.println("");

    System.out.println("Are you Male or Female?");
    System.out.println("M for Male F for female: ");
    String sex = input.nextLine();
    String male = "M";
    String female = "F";

    if(sex.equalsIgnoreCase(male)){
        System.out.println("Hello Mr. " + fullName1 + " Welcome to the party!");
    }else if(sex.equalsIgnoreCase(female)){
        System.out.println("Hello Ms. " + fullName1 + " Welcome to the party!");
    }
    System.out.println("");
}
public static boolean userenter(boolean yes){
    Scanner input = new Scanner(System.in);
    System.out.println("Are you with a company? Yes/No");
    String ans = input.nextLine();
    String y = "yes";

    if (ans.equalsIgnoreCase(y)){
        userenter("withmate");
    }else
        System.out.println("Have a Good Day ahead!");
    return yes;
}
public static void userenter(String withmate){
    Scanner input = new Scanner(System.in);
    System.out.println("Enter your mates Fullname: ");
    String fullname = input.nextLine();

    System.out.println("");

    System.out.println("Are you Male or Female?");
    System.out.println("M for Male F for female: ");
    String sex = input.nextLine();
    String male = "M";
    String female = "F";

    if(sex.equalsIgnoreCase(male)){
        System.out.println("Hello Mr. " + fullname + " and " + fullName1 + " Welcome to the party!");
    }else if(sex.equalsIgnoreCase(female)){
        System.out.println("Hello Ms. " + fullname + " and " + fullName1 + " Welcome to the party!");
    }
    System.out.println("");
}

}

Answer 2

In response to your question:

In that case yes, you'll have to create a global variable for their gender. I've simplified the code for you for demonstration:

import java.util.*;
public class OverloadingFG2 {

public static String fullName1;
public static String gender1;

public static void main(String[] args) {

    userenter();
    userenter(false);
}

public static void userenter() {
    Scanner input = new Scanner(System.in);
    System.out.println("Enter your Fullname: ");
    fullName1 = input.nextLine();

    System.out.println("");

    System.out.println("Are you Male or Female?");
    System.out.println("M for Male F for female: ");
    String sex = input.nextLine();
    gender1 = (sex.equalsIgnoreCase("M") ? "Mr. " : "Ms. ");

    System.out.println("Hello " + gender1 + fullName1 + " Welcome to the party!");
    System.out.println("");
}

public static boolean userenter(boolean yes) {
    Scanner input = new Scanner(System.in);
    System.out.println("Are you with a company? Yes/No");
    String ans = input.nextLine();
    String y = "yes";

    if (ans.equalsIgnoreCase(y)) {
        userenter("withmate");
    } else
        System.out.println("Have a Good Day ahead!");
    return yes;
}

public static void userenter(String withmate) {
    Scanner input = new Scanner(System.in);
    System.out.println("Enter your mates Fullname: ");
    String fullname = input.nextLine();

    System.out.println("");

    System.out.println("Are you Male or Female?");
    System.out.println("M for Male F for female: ");
    String sex = input.nextLine();
    String gender2 = (sex.equalsIgnoreCase("M") ? "Mr. " : "Ms. ");

    System.out.println("Hello " + gender2 + fullname + " and " + gender1 + fullName1 + " Welcome to the party!");
    System.out.println("");
}

}
