带有方法声明的非法表达式开头

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

公共静态 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，因为我关注 this tutorial 并使用了一个非常相似的示例代码。

提前感谢您的帮助。

  // 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;
  }
  }

Answer 1

      if (a != b) {
              System.out.println ("The smaller number is " + c);
      }
      else {
              System.out.println ("The two numbers are equals.");
      } // <----- was not present

此行缺少花括号。
