非法开始表达(方法) [英] Illegal start of expression (method)

问题描述

决定最近要学习一点Java，但我遇到了第一个障碍.这是我极其基本的代码:

decided to recently learn a little bit of java and I've been stumped at the first hurdle. Here is my extremely basic code:

import java.util.Scanner;

class helloWorld{

public static void main(String[] args){
    Scanner user_input = new Scanner(System.in);

    int a = 50;
    String first_name;
    String last_name;

    public static int funcName(int a, int b) {
    }
}
}

据我所知，没有错误.但是，在编译时我收到此错误:

As far as I can see, there are no errors. However, at compile time I receive this error:

Dominics-MacBook-Pro:helloworld dominicsore$ javac helloworld.java
helloworld.java:12: error: illegal start of expression
public static int funcName(int a, int b) {
^
helloworld.java:12: error: illegal start of expression
public static int funcName(int a, int b) {
       ^
helloworld.java:12: error: ';' expected
public static int funcName(int a, int b) {
             ^
helloworld.java:12: error: '.class' expected
public static int funcName(int a, int b) {
                               ^
helloworld.java:12: error: ';' expected
public static int funcName(int a, int b) {
                                ^
helloworld.java:12: error: ';' expected
public static int funcName(int a, int b) {
                                       ^
6 errors

我进行了搜索，所有常见的回答都是错别字和括号放错了位置，但据我所知并非如此.

I've searched and searched and all the usual responses are typos and misplaced brackets but as far as I can see this isn't the case.

不确定是否会有所不同，但是我使用的是vim编辑器，并且正在从终端进行编译.

Not sure if it will make any difference but I am on a mac, using the vim editor and I'm compiling from terminal.

任何建议都值得赞赏.

推荐答案

funcName是在main方法中定义的，它必须在main方法之外:

funcName is being defined from within the main method, it must be outside it:

import java.util.Scanner;

class helloWorld{

    public static void main(String[] args){
        Scanner user_input = new Scanner(System.in);

        int a = 50;
        String first_name;
        String last_name;
    }
    public static int funcName(int a, int b) {

    }
}
