编写程序，针对各种数据类型各声明一个变量，初始化并输出其值

public static void main(String[] args) {
            //基本数据类型
            boolean initBoolean = false;
            byte initByte = 12;
            short initShort = -2000;
            int initInt = 0;
            long initLong = 1l;
            float initFloat = 6f;
            double initDouble = 7d;
            String initChar = "abc";

            //引用数据类型
            int[] initIntArr = {20,68,34,22,34};
            System.out.println("initBoolean: " + initBoolean);
            System.out.println("initByte: " + initByte);
            System.out.println("initShort: " + initShort);
            System.out.println("initInt: " + initInt);
            System.out.println("initLong: " + initLong);
            System.out.println("initFloat: " + initFloat);
            System.out.println("initDouble: " + initDouble);
            System.out.println("initChar: " + initChar);
            System.out.println("initIntArr: " + initIntArr);
            ArrayList<String> sites = new ArrayList<String>();
            sites.add("Google");
            sites.add("Runoob");
            sites.add("Taobao");
            sites.add("Weibo");
            System.out.println("initArrayList: " + sites);

        }
