需要帮助格式化Java中特定类型的String

Question

I am new in java String formatting concept so need help. I have a string something like [MALE] and i need remove those braces and get MALE. How to get it done?

Answer 1

You cannot modify a String in java so you will need to use a StringBuilder . If you want to use the atomic bomb, use a regular expression. Otherwise just checkout the StringBuilder methods in the doc and do what you wish.

You can turn it back to a String afterwards.

Answer 2

这会..

yourString=yourString.substring(1, yourString.length-1)

Answer 3

public class Remove {
public static void main(String [] args){
    String string = "[MALE]";
    string = string.replaceAll("\\[", "");
    string = string.replaceAll("\\]", "");
    System.out.println(string);
}

}

Answer 4

You can use StringBuilder

 StringBuilder sb=new StringBuilder();
 sb.deleteCharAt(sb.indexOf("["));
 sb.deleteCharAt(sb.indexOf("]"));

For String(This looks like a workaround):

 String s="[SBD]";
  s=  s.replace("[","");
   s= s.replace("]","");

Please note that if more than one "[" or "]" it will replace all occurences.
