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; } }

if (a != b) {
System.out.println ("The smaller number is " + c);
}
else {
System.out.println ("The two numbers are equals.");
} // <----- was not present
这里的这一行缺少花括号。
