String time = "17.2";
String [] info = time.split("\\."); //点需要字符转义，而反斜杠有时转义字符，所以需要两个

Answer 6

String[] java.lang.String.split(String regex)
参数是正则表达式~而.在正则中代表任意字符,用.本身就要转义~

String time="17.2"; 
                    String[] info = time.split("\\."); 
                    System.out.println("info[0]=" + info[0]); 
                    System.out.println("info[1]=" + info[1]);

}

Answer 9

        String time="17.2"; 
        String[] info = time.split("\\."); //.为转义字符 
        System.out.println(info[0] + "," + info[1]);
