Java 乘法（PrintStream 类型不适用于参数 (String, int)）

Question

任意数的

Table 收到此错误 - 在 System.out.println(number+" x "+i+" = ",+number*i);

(PrintStream 类型不适用于参数 (String, int))

package JAVAS;
import java.util.Scanner;
public class number {

    public static void main(String[] args) {
Scanner num = new Scanner(System.in);
System.out.println("Enter the number ??");
int number = num.nextInt();
int i=1;
System.out.println("the table of the following number is ");
while (i <= 10)
{
    System.out.println(number+" x "+i+" = ",+number*i);
    i++;
}
        
    }
}

你的问题是你的 println 中多了一个逗号。但是，为了清楚起见并向您展示执行此操作的更好方法，请考虑以下内容：

public static void main(String[] args) throws IOException {
    try (Scanner scanner = new Scanner(System.in)) {
        System.out.println("Enter the number ??");
        int number = scanner.nextInt();
        System.out.println("the table of the following number is ");
        String format = "%d x %d = %d";
        for (int i = 1; i < 11; i++) {
            System.out.println(String.format(format, number, i, number * i));
        }
    }
}
