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);
    }
}

Output:

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);
    }
}

Output:

c1 is a space character? false
c2 is a space character? true
