如何检查字符串是否以精确字符串结尾？

Question

The input is XYZ

The String array contains three string ie

1. test.alpha.beta.XYZWorld
2. test.gamaa.mu.XYZ
3. 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.

Answer 1

String有一个endsWith()方法。

Answer 2

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

Answer 3

    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
    }
