Java “基本计算”；此行有多个标记语法错误，请删除此标记；

您好，我刚刚开始学习java，在一些非常基本的计算方面遇到了困难。这个简单的程序要求用户输入两个值，然后当它运行时，我希望它显示“20+5=25”。但是，我在行的这一部分反复收到“语法错误，删除此令牌”消息

“+“num2”=“num1

”。怎么了

package ner.cs1451;

import java.util.Scanner;

public class Project01a {
/*This program asks the user to input two values
 *Then computes the following: sum, difference, product, quotient, remainder, and the average.*/

    public static void main(String[] args) {


        Scanner in = new Scanner(System.in);


        System.out.print("Enter the first number: ");
        int num1 = in.nextInt();
        System.out.print("Enter second number: ");
        int num2 = in.nextInt();
        int avg = (num1 + num2)/2;


        System.out.println(num1 "+" num2 "=" num1 + num2);
        System.out.println(num1 "-" num2 "=" num1 - num2);
        System.out.println(num1 "*" num2 "=" num1 * num2);
        System.out.println(num1 "/" num2 "=" num1 / num2);
        System.out.println(num1 "%" num2 "=" num1 % num2);
        System.out.println("The average of your two numbers is: "+avg);

您在尝试连接的所有值之间缺少连接运算符

+

。例如

System.out.println(num1 + "+" + num2 + "=" + (num1 + num2));

您还需要将加法用括号括起来，以便在数字之间进行正常加法，而不是串联。

将字符串串联起来，如下所示：

System.out.println（num1+“+”+num2+“=”+（num1+num2））
