![]() equalsIgnoreCase() method makes the case-insensitive comparison.The regex functions in R have ignore.case as their only option. equals() method makes the case-sensitive comparison. The handy String.matches() method in Java does not take a parameter for matching options.Difference between equals() and equalsIgnoreCase()Ĭlearly, the primary difference between equals() and equalsIgnoreCase() APIs is their case sensitivity while performing the comparisons. Assertions.assertFalse("null".equalsIgnoreCase(null)) Īssertions.assertFalse("abc".equalsIgnoreCase("abcd")) //Different stringsĪssertions.assertTrue("abc".equalsIgnoreCase("ABC")) Īssertions.assertTrue("ABC".equalsIgnoreCase("AbC")) 3. Java does not have a built-in Regular Expression class, but we can import the package to work with regular expressions. Regular expressions can be used to perform all types of text search and text replace operations. Also, equalsIgnoreCase() returns false when the strings have different content. A regular expression can be a single character, or a more complicated pattern. We can see that passing null returns false. Returns 'TRUE' if the 'i' modifier is set, 'FALSE' otherwise. It specifies whether a particular regular expression performs case-insensitive matching, i.e., whether it was created with the 'i' attribute. has the value true if the i flag was used otherwise, false. The following Java program demos a few comparisons using the equalsIgnoreCase() API. ignoreCase is a read-only boolean property of RegExp objects. Note that if we pass null as the method argument, the comparison result will be false. The syntax to use the equalsIgnoreCase() API is as follows: boolean isEqual = thisString.equalsIgnoreCase( anotherString ) ![]() It checks the object references, which is not desirable in most cases. Never use ' =' operator for checking the strings equality. Ive tried a few variants but cant seem to get any to work My latest feeble attempt was. However, I would like it to exclude a couple of string values such as /ignoreme and /ignoreme2. This matches strings such as /hello or /hello123. Using equalsIgnoreCase(), two strings are considered equal if they are of the same length and corresponding characters in the two strings are equal, ignoring their cases.Ī similar method String.equals() compares the strings in a case-sensitive manner. I have a regular expression as follows: / a-z0-9 .
