使用 javac 編譯這個簡單的代碼,它給了我以下錯誤Test3.java:38: 錯誤:表達式的非法開始public static int minFun (int a, int b) {我嘗試在 main 之外聲明變量(即 public static int a、b、c),但沒有任何改變。這讓我感到困惑,因為我在學習本教程時使用了一個非常相似的示例代碼。在此先感謝您的幫助。 // 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
這里的這一行缺少花括號。
