how to check whether the string ends with exact string?

Question

The input is XYZ

The String array contains three string i.e.

test.alpha.beta.XYZWorld
test.gamaa.mu.XYZ
test.nu.tera.XYZ

I need the last two result if i provide the input "XYZ". Not the test.alpha.beta.XYZWorld. if i use lastIndexOf method defined in java.lang.String, obviously it returns 1,2 and 3 result.

Please help.

Have you looked at the endsWith(String suffix) method in String class ? — jlordo

Your lastIndexOf has to be exactly the length of your input smaller than the length of your test string. In the case of test.alpha.beta.XYZWorld, it will be less than that. — milivojeviCH

There is an endsWith() method in String.

can we do this?:first change toCharArray say a[] if(a[i]=='X'&&a[i+1]=='y'&&a[i=2]=='z'&&a[i+3]=='\0'){ //end string }

You can do that, but it is ugly.

yeah endsWith() is better :)

    String pattern = "xyz";
    String a = "xyz";
    String b = "xyzA";

    int position = b.lastIndexOf(pattern);
    if (b.length() == position + pattern.length())
    {
       System.out.print("OK");
    } else
    {
        //error
    }

check out String.endsWith(suffix) method from String API. it returns a boolean value.

  String s = "test.gamaa.mu.XYZ";
  System.out.println(s.endsWith("XYZ"));

  returns TRUE
