带有方法声明的表达式的非法开头

Question

使用 javac 编译这个简单的代码，它给了我以下错误

Test3.java:38: 错误：表达式的非法开始

public static int minFun (int a, int b) {

我尝试在 main 之外声明变量（即 public static int a、b、c），但没有任何改变。

这让我感到困惑，因为我在学习本教程时使用了一个非常相似的示例代码。

在此先感谢您的帮助。

  // Program to output the minimum of two integer numbers

  import java.io.*;

  public class Test3 {

  public static void main (String args[]) {

          int a, b, c;

          String rA, rB;

          InputStreamReader input = new InputStreamReader (System.in);

          BufferedReader keyboard = new BufferedReader (input);

          System.out.println ("Please, enter two integer numbers.");

          try {

                  rA = keyboard.readLine ();

                  a = Integer.parseInt (rA);

                  rB = keyboard.readLine ();

                  b = Integer.parseInt (rB);

          }

          catch (IOException e) {

                  System.err.println ("Not a proper integer number.");

          }

          catch (NumberFormatException e) {

                  System.err.println ("Not a proper integer number.");

          }

          c = minFun (a, b);

          if (a != b) {

                  System.out.println ("The smaller number is " + c);

          }

          else {

                  System.out.println ("The two numbers are equals.");

  }

  public static int minFun (int a, int b) {

          int min;

          if (a < b) {

                  min = a;

          }

          else {

                  min = b;

          }

          return min;

  }

  }
