Java数组
声明
double[] myList; // 首选的方法 double myList[]; // 效果相同，但不是首选方法 创建 public class TestArray { public static void main(String[] args) { // 数组大小 int size = 10; // 定义数组 double[] myList = new double[size]; myList[0] = 13.6; myList[1] = 14.53; myList[2] = 323.34; myList[3] = 123.24; myList[4] = 44.05; myList[5] = 334.343; myList[6] = 344.50; myList[7] = 45.445; myList[8] = 9.4; myList[9] = 11452; // 计算所有元素的总和 double total = 0; for (int i = 0; i < size; i++) { total += myList[i]; } System.out.println("总和为： " + total); } } 处理 public class TestArray { public static void main(String[] args) { double[] myList = {0.5, 2.6, 3.3, 4.2}; // 打印所有数组元素 for (int i = 0; i < myList.length; i++) { System.out.println(myList[i] + " "); } // 计算所有元素的总和 double total = 0; for (int i = 0; i < myList.length; i++) { total += myList[i]; } System.out.println("Total is " + total); // 查找最大元素 double max = myList[0]; for (int i = 1; i < myList.length; i++) { if (myList[i] > max) max = myList[i]; } System.out.println("Max is " + max); } }
