Example

The following example shows the usage of lang.Character.isSpaceChar() method.

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 2 char primitives ch1, ch2
      char ch1, ch2;

      // assign values to ch1, ch2
      ch1 = ' ';
      ch2 = '\u2028';  // LINE_SEPARATOR

      // create 2 boolean primitives b1, b2
      boolean b1, b2;

      /**
       *  check if ch1, ch2 are space characters
       *  and assign results to b1, b2
       */
      b1 = Character.isSpaceChar(ch1);
      b2 = Character.isSpaceChar(ch2);

      String str1 = "ch1 is a space character is " + b1;
      String str2 = "ch2 is a space character is " + b2;

      // print b1, b2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result:

ch1 is a space character is true
ch2 is a space character is true
