格式化字符串：删除电话号码

Question

I'm having a String(StringTo) such as

John [0775678899] ,Ann [0776789988] ,Mary [0777789900] 

But I need to format the string to display it as:

John, Ann, Mary

I tried using the below method but it didn't give me the expected result:

StringTo = StringTo.replace("//[^10] ,/", ", ");

Can someone tell me whats wrong or any other way to compute this?

Answer 1

用空字符串替换正则表达式\\[\\d+\\]

Answer 2

Try this, it will format the white-space properly:

StringTo = StringTo.replaceAll("\\s*\\[\\d+\\]\\s*(,?)", "$1 ");

Input:

John [0775678899] ,Ann [0776789988] ,Mary [0777789900] 

Output:

John, Ann, Mary 

Answer 3

If I understood you correctly - you need to remove all numbers inside [] . Try this:

StringTo.replaceAll("\\[.*?\\] ","");

Answer 4

public static void main(String[] args) {
    String s = "John [0775678899] ,Ann [0776789988] ,Mary [0777789900]";
    String[] ss = s.split(",");
    ArrayList<String >name = new ArrayList<String>();
    for(int i = 0; i< ss.length; i++){
        String[]splitted = ss[i].split("\\[");
        name.add(splitted[0]);
    }
    System.out.println(name);
}

Output:

[John , Ann , Mary ]
