英文:
Getter isn't returning anything when I try to print using the get method
问题
我在主类中创建了一个对象，并将所有相关参数传递给了"member"类的构造函数。
但是，当我尝试调用getName()来打印姓名时，它打印出一个空格...
任何提示都会有所帮助
while (true) {
System.out.print("姓名：");
String nameInput = input.nextLine();
input.next();
System.out.print("号码：");
String number = input.nextLine();
input.next();
try {
System.out.println("类型：\n1/2/3...?");
int choice = input.nextInt();
switch (choice) {
case 1: {
member object1 = new member(nameInput, number);
System.out.println("默认姓名：" + object1.getName());
}
case 2: {
// 这只是一个示例打印
System.out.println("选择了第二种情况");
}
case 3: {
System.out.println("选择了第三种情况");
}
default: {
System.out.println("错误");
}
}
} catch (InputMismatchException e) {
System.out.println("错误");
input.next();
}
}
这是"member"类：
public class member {
private String Name;
private String Number;
public member(String name, String number) {
Name = name;
Number = number;
}
public String getName() {
return Name;
}
public String getIDNumber() {
return Number;
}
}
英文:
I have created a object in the main class and gave all the relevant parameters to the constructor in the "member" class.
But, when I tried to print the name by calling the getName() it prints a empty space...
Any tips would be helpful
while (true) {
System.out.print("Name :");
String nameInput=input.nextLine();
input.next();
System.out.print("Number : ");
String number=input.nextLine();
input.next();
try {
System.out.println("Type: \n 1/2/3...?");
int choice=input.nextInt();
switch (choice){
case 1:{
member object1=new member(nameInput,number);
System.out.println("Default name : "+object1.getName());
} case 2:{
//this is just a sample print
System.out.println("Case 2 selected");
} case 3:{
System.out.println("Case 3 selected");
} default:{
System.out.println("Error");
}
}
}catch (InputMismatchException e){
System.out.println("Error");
input.next();
This is the member class
public class member {
private String Name;
private String Number;
public member(String name, String number) {
Name = name;
Number = number;
}
public String getName() { return Name; }
public String getIDNumber() { return Number;}
}

自定义构造函数必须与类名完全相同（包括大小写），在开关的情况1中，您将对象命名为<b>关键字对象</b>，请尝试更改这些内容！
英文:
The custom constructor must be the same exact name as the class name(upper and lower case included), also in the case 1 of the switch you named the object with the <b>keyword Object</b> , try changing those things!!

问题在于你的构造函数。构造函数是一个特殊的方法，其名称与类名匹配。请使用大写字母来表示类名。
英文:
the problem is in your constructor. Constructor is a special method where name match with class name. and please use uppercase for class name
