java - 如何将用户输入添加到java中的数组中？

Question

public static void main(String[] args) {
    Scanner user_input = new Scanner(System.in);
    int i;
    int n;
    String a;     
    System.out.println("Enter the Class:");
    a = user_input.next();
    System.out.println("Enter the number of Students:");
    n = user_input.nextInt();
    for (i= 1; i <= n; i++) {
        String g = a + i;
        System.out.println(g);
    }
}

这是我的程序。它获取类(class)的用户输入并为学生打印卷号。

例如:如果类(class)为 10A，学生人数为 10，则打印一系列 10A1 , 10A2, 10A3 ... 10A10

如何让程序将它们存储为数组中的元素？

例如:

array[0] = 10A1;
array[1] = 10A2;
array[2] = 10A3; 

等等

您的代码应如下所示:

public static void main (String args[])
{
    Scanner user_input = new Scanner(System.in);
    int i;
    int n;
    String a;
    System.out.println("Enter the Class:");
    a = user_input.next();
    System.out.println("Enter the number of Students:");
    n = user_input.nextInt();
    String []strings = new String[n]; // Creating an are of string with the given number
    for(i= 0; i < n ;){
        strings[i] = a + ++i; // Storing strings on to the array !
        System.out.println(strings[i-1]);
    }
}
