The java.lang.Character.isTitleCase() in an inbuilt method in java which determines if the specified character is a titlecase character or not. A character is a titlecase character if its general category type, provided by getType(codePoint), is a TITLECASE_LETTER.
Some characters look like pairs of Latin letters. For example, there is an uppercase letter that looks like “LJ” and has a corresponding lowercase letter that looks like “lj”. A third form, which looks like “Lj”, is the appropriate form to use when rendering a word in lowercase with initial capitals, as for a book title.
Given below are some of the Unicode characters for which this method returns true:
- LATIN CAPITAL LETTER D WITH SMALL LETTER Z WITH CARON
- LATIN CAPITAL LETTER L WITH SMALL LETTER J
- LATIN CAPITAL LETTER N WITH SMALL LETTER J
- LATIN CAPITAL LETTER D WITH SMALL LETTER Z
Syntax:
public static boolean isTitleCase(char ch)
Parameter:The function accepts only one mandatory parameter ch which signifies the character to be tested.
Return Value: This method returns true if the character is titlecase else it returns false.
Below program illustrate the isTitleCase() method:
// Java program to demonstrate// Character.isTitleCase() methodimport java.lang.*;public class gfg { public static void main(String[] args) { // Assign values to ch1, ch2 char ch1 = 'Z'; char ch2 = '\u01f2'; // Function to check if the // character is a title case or not boolean b1 = Character.isTitleCase(ch1); boolean b2 = Character.isTitleCase(ch2); System.out.println(ch1 + " is a titlecase character is " + b1); System.out.println("unicode \u01f2 is a titlecase character is " + b2); }} |
Z is a titlecase character is false unicode ? is a titlecase character is true
