Java-从数组方法返回一个数组到Main函数

Question

public static public static void main(String[] args) {
    System.out.print("Enter the number of student names to input: ");
    int studentNum = new Scanner(System.in).nextInt();
    String students[ ] = new String[studentNum];
    for(int i = 0; i<studentNum; i++){
        students[ i ] = inputStudent(i+1);
    }
}

public static String[] inputStudent(int i) {
    String studentNum[] = new String[i];
    for(int a=0; a<i; a++) {
        System.out.print("Enter student name"+(a+1)+": ");
        studentNum[a]=new Scanner(System.in).nextLine();
    }
    return studentNum;
}

错误:

students[ i ] = inputStudent(i+1);

它说:

incompatible types: String[] cannot be converted to String

PS:main 函数不应修改。

Answer 1

您正在尝试将字符串数组分配给字符串

即

inputStudent(int i) 返回 Array，但您试图将 Array 分配给 students[ i ] = inputStudent(i+1);作为String[i] 是元素 String 数组，仅接受 String
