我该咋写才能写出跟效果图一毛一样

    public static void main(String[] args) {
        String[] world=new String[]{"TMD","日","狗"};
        Scanner scanner=new Scanner(System.in);
        while(true) {
            System.out.print("请输入检测的字符串：");
            String str=scanner.nextLine();
            for (int i = 0; i < world.length; i++) {
                str=str.replaceAll(world[i], "*");
            }
            System.out.println(str);
            System.out.println("是否继续检测：（继续：true，结束：false）");
            String flag=scanner.nextLine();
            if(flag.equals("false")) {
                System.out.println(" --结束输入--");
                break;
            }
        }
    }
