我有一个名为Student
的类,其数据成员为:
private String name;
private long idNumber;
使用正确的getter和setter方法。
我需要创建一个名为StudentTest
的测试人员类,其中包括以下方法:
public static Student[] createArray()
public static void populateArray(Student[] array)
public static void displayArray(Student[] array)
当我尝试编译测试人员类时,我收到“找不到符号”错误。
这是我的测试人员类:
// Scanner class from the Java API
import java.util.Scanner;
public class StudentTester {
public static void main(String[] args) {
// Call methods
Student[] studentList = createArray();
populateArray(studentList);
displayArray(studentList);
} // end main
// Create Array Method
public static Student[] createArray() {
// Declaration & Creation of Scanner object
Scanner input = new Scanner(System.in);
// Create Array
System.out.println("Enter size of array: ");
int i = input.nextInt();
Student[] studentList = new Student[i];
return studentList;
}
// Populate Array Method
public static void populateArray(Student[] array) {
for(int i = 1; i < studentList.length; i++) {
studentList[i] = new Student();
Scanner userInput = new Scanner(System.in);
// Get Input for Name
System.out.println("Enter Student Name: ");
studentList[i].setName = userInput.nextLine();
// Get Input for Id Number
System.out.println("Enter Student ID Number: ");
studentList[i].setIdNumber = userInput.nextInt();
}
}
// Display Array Method
public static void displayArray(Student[] array) {
System.out.println("Array Contents");
for(int j = 0; j < studentList.length; j++) {
System.out.println(studentList[j].getName() + " " + studentList[j].getIdNumber());
}
}
} // end class
请任何人帮助我,我对java很新。
我的Student
班级
public class Student {
// Data Members
private String name;
private int idNumber;
// Constructor
public Student() {
name = "Unassigned";
idNumber = 0;
}
// Getters
public String getName(){
return name;
}
public int getIdNumber(){
return idNumber;
}
// Setters
public void setName(String name){
this.name = name;
}
public void setIdNumber(int idNumber){
this.idNumber = idNumber;
}
} // end class
无法找到的符号与数组本身studentList
答案 0 :(得分:0)
populateArray
(和displayArray
)正在尝试使用studentList
,但您在参数中将其命名为array
。重命名,如
public static void populateArray(Student[] studentList) { // <-- not array.
public static void displayArray(Student[] studentList) { // <-- and here.
或在您的方法中使用array
代替studentList
。
