用方法声明非法开始表达式

Question

使用javac编译此简单代码，会给我以下错误

  

Test3.java:38：错误：表达式的非法开头

     

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

我试图在主变量之外声明变量（即public static int a，b，c），但没有任何改变。

自从我遵循this tutorial以来，使用了非常相似的示例代码，这使我感到困惑。

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;
  }
  }

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

此行缺少大括号。
