导入扫描仪时一直出错[关闭]

Question

我想知道为什么我的 java 扫描器不工作

我尝试了很多东西，但我的扫描仪和导入 java.util 不工作。请看下面

package com.mycompany.theatre;
import java.util.scanner;


public class Theatre {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        
        System.out.println("Welcome to the New Theatre");
        
        
        int[] row1 = new int[12];
        int[] row2 = new int[16];
        int[] row3 = new int[20];
        
        for (int i = 0; i < row1.length; i++) {
            row1[i] = 0;         
        }
        for (int i = 0; i < row2.length; i++) {
            row2[i] = 0;
        }
        for (int i = 0; i < row3.length; i++) {
            row3[3] = 0;
        }
    }
}
