Character.isSpaceChar() method in Java
The java.lang.Character.isSpaceChar(char ch) is an inbuilt method in java which determines if the specified character is a Unicode space character. A character is considered to be a space character if and only if it is specified to be a space character by the Unicode Standard.
This method returns true if the character’s general category type is any of the following ?
- SPACE_SEPARATOR
- LINE_SEPARATOR
- PARAGRAPH_SEPARATOR
Syntax:
public static boolean isSpaceChar(char ch)
Parameter: The function accepts one mandatory parameter ch which specifies the character to be tested.
Return Value: This method returns a boolean value. The value is True if the character is a space character, False otherwise.
Below programs illustrate the Character.isSpaceChar() method:
Program 1:
// Java program to illustrate the // Character.isSpaceChar() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives c1, c2 and assign values char c1 = '$' , c2 = '\u2025' ; // Function to check if the character is a unicode space or not boolean bool1 = Character.isSpaceChar(c1); System.out.println( "c1 is a space character? " + bool1); // Function to check if the character is a unicode space or not boolean bool2 = Character.isSpaceChar(c2); System.out.println( "c2 is a space character? " + bool2); } } |
c1 is a space character? false c2 is a space character? false
Program 2:
// Java program to illustrate the // Character.isSpaceChar() method import java.lang.*; public class gfg { public static void main(String[] args) { // create 2 char primitives // c1, c2 and assign values char c1 = '*' , c2 = '\u2028' ; // Function to check if the character is a unicode space or not boolean bool1 = Character.isSpaceChar(c1); System.out.println( "c1 is a space character? " + bool1); // Function to check if the character is a unicode space or not boolean bool2 = Character.isSpaceChar(c2); System.out.println( "c2 is a space character? " + bool2); } } |
c1 is a space character? false c2 is a space character? true
