學習java數組的基礎

public class TestArray {

public static void main(String[] args) {

// 數組大小

int size = 10;

// 定義數組

double[] myList = new double[size];

myList[0] = 5.6;

myList[1] = 4.5;

myList[2] = 3.3;

myList[3] = 13.2;

myList[4] = 4.0;

myList[5] = 34.33;

myList[6] = 34.0;

myList[7] = 45.45;

myList[8] = 99.993;

myList[9] = 11123; // 計算所有元素的總和

double total = 0;

for (int i = 0; i < size; i++) {

total += myList[i];

}

System.out.println("總和爲： " + total); }}
