JNI学习三-简单类型数组访问

class PrimitiveArrayDemo { private native int sum(int [] intArray, int num); public static void main(String [] args) { PrimitiveArrayDemo demo = new PrimitiveArrayDemo(); int num = 10; int [] intArray = new int[num]; for(int i = 0; i < num; ++i) { intArray[i] = i; } int sum = demo.sum(intArray, num); System.out.println("sum of intArray is " + sum); } static { System.loadLibrary("PrimitiveArrayDemo"); } }
