//一维数组
String[] str = new String[5]; //创建一个长度为5的String(字符串)型的一维数组
str[0] = "a"; //赋值
str[1] = "b";
str[2] = "c";
str[3] = "d";
str[4] = "e";
//也可以创建并赋值
String[] str = {"a","b","c","d","e"};
//二维数组
String[][] str = new String[2][2]; //创建一个2行2列的二维数组
str[0][0] = "a0"; //赋值
str[0][1] = "a1";
str[1][0] = "b0";
str[1][1] = "b1";
//也可以创建并赋值
String[][] str = {{"a0","a1"},{"b0","b1"}};
总结:
类型名[]/[][] 变量名 = new 类型名[]/[][];
