Java 数组

使用：

int[] myArray = new int[5];

myArray[0] = 10; // 索引从0开始
myArray[1] = 20;

二维数组：

[
    [“张三”, 18, “男”],
    [“李四”, 20, “女”],
    [“王五”, 19, “男”],
    [“赵六”, 17, “女”],
    [“赵七”, 22, “男”]
]

或（？）：

String[][] students = {
        {"张三", "18", "男"},
        {"李四", "20", "女"},
        {"王五", "19", "男"},
        {"赵六", "17", "女"},
        {"赵七", "22", "男"}
};
for (int i = 0; i < students.length; i++) {
    System.out.println("姓名：" + students[i][0] + "，年龄：" + students[i][1] + "，性别：" + students[i][2]);
}
