How to check that entered string contains Unicode: 0x1a value

Question:

I want to know that entered string is contains Unicode:0x1a value or not in java. I am not able to identify the value of → and other special character.

Answer1:

Because the character "→" has a Unicode code point \u2192.

String s = "this is → my arrow"; if (s.contains("→")) { System.out.println("Contains arrow!"); } else { System.out.println("No arrows in my string :("); }

As an alternative you may write the character in hex notation:

String s = "this is → my arrow"; if (s.contains("\u2192")) { System.out.println("Contains arrow!"); } else { System.out.println("No arrows in my string :("); }
