错误:不兼容的类型:意外的返回值Char与String比较

问题描述

我正在尝试将char与String进行比较，但出现错误.错误

I am trying to compare char to a String but getting an error.Error

error: incompatible types: unexpected return value

代码:

public class MyClass {
    public static void main(String args[]) {
        String s = Integer.toBinaryString(2432);
        String p = "0";

        for (char c : s.toCharArray()) {
            return p.equals(new String(new char[]{c}));
        }
    }
}

推荐答案

main()的类型为void(public static void main(String args[]) {) 因此，您不能从中返回值.

The type of main() is void (public static void main(String args[]) {) and therefore you cannot return a value from it.

我运行此命令时收到的实际错误是:

The actual error I get when I run this is:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
Void methods cannot return a value
