Question

您好我的代码需要帮助。我试图使用扫描仪和方法制作用户基础输入乘法表，但我不知道如何从主方法获得用户基础输入到我创建的方法，这是我到目前为止：

public static void multiplicationTable(int i){
for (int i=1;i<=size;i++){
for (int j=1;j<=size;j++)
System.out.print("\t"+i*j);
System.out.println(); }
}
public static void main (String[] args) {
System.out.println("This program displays a multiplication table.");
Scanner size = new Scanner(System.in);
System.out.println("Enter a positive integer: ");
int n = size.nextInt ();
}

Answer 1

你可以传递：

    System.out.println("This program displays a multiplication table.");
    Scanner size = new Scanner(System.in);
    System.out.println("Enter a positive integer: ");
    int n = size.nextInt ();
    multiplicationTable(n); \\ pass here

Answer 2

实际上你的代码非常封闭。请看下面（我已经测试过代码）：

public static void multiplicationTable(int size) {
    for (int i = 1; i <= size; i++) {
        for (int j = 1; j <= size; j++) {
            System.out.print("\t" + i * j);
        }
        System.out.println();
    }
}

public static void main(String[] args) throws Exception {
    System.out.println("This program displays a multiplication table.");
    Scanner size = new Scanner(System.in);
    System.out.println("Enter a positive integer: ");
    int n = size.nextInt();
    multiplicationTable(n);
}

基于用户的乘法表
