我在下面的這個程序中遇到了一件事，它是......當在方法 numTest 中它用逗號分隔時，值“17”如何到達方法 isPrime 并且我找不到這個值“17”的任何轉移到這個方法？非常感謝你幫助我走得更遠。任何人都可以向我解釋價值“17”的運動嗎？// Demonstrate a method reference for a static method. // A functional interface for numeric predicates that operate // on integer values. interface IntPredicate {   boolean test(int n); } // This class defines three static methods that check an integer // against some condition. class MyIntPredicates {   // A static method that returns true if a number is prime.   static boolean isPrime(int n) {     if(n < 2) return false;     for(int i=2; i <= n/i; i++) {       if((n % i) == 0)          return false;     }     return true;   }   // A static method that returns true if a number is even.   static boolean isEven(int n) {     return (n % 2) == 0;   }   // A static method that returns true if a number is positive.   static boolean isPositive(int n) {     return n > 0;   } }     class MethodRefDemo {   // This method has a functional interface as the type of its   // first parameter. Thus, it can be passed a reference to any   // instance of that interface, including one created by a   // method reference.   static boolean numTest(IntPredicate p, int v) {     return p.test(v);   }   public static void main(String args[])   {     boolean result;     // Here, a method reference to isPrime is passed to numTest().     result = numTest(MyIntPredicates::isPrime, 17);     if(result) System.out.println("17 is prime.");     // Next, a method reference to isEven is used.     result = numTest(MyIntPredicates::isEven, 12);     if(result) System.out.println("12 is even.");      // Now, a method reference to isPositive is passed.     result = numTest(MyIntPredicates::isPositive, 11);     if(result) System.out.println("11 is positive.");   } }
