How to check if a field contains a hyphen character in java

Question

My object returns to me - from Log.d ("FormattedDate", Object.getDOB ());

 if (!Object.getDOB().matches("[^-]*")) { txtDOB.setText(Object.getDOB()); } else { txtDOB.setText("-"); } 

I check if my Object.getDOB () matches with - and then shows emptry lines, but this regExp does not work.

Answer 1

java.lang.String has String # contains () which does this for you:

Returns true if and only if this string contains the specified sequence of char values.

 if (Object.getDOB().contains("-")) { //code } 

Answer 2

You can also use

 if (Object.getDOB().indexOf("-") != -1) { //code } 

if it returns -1 , then the string does not contain char (in your case, "-" ). Otherwise, it returns a char index.

Answer 3

You can use contains() in java to search which is available in String class

Returns true if and only if this string contains the specified sequence of char values.

 getDOB().contains("-")
