How to count spaces in a string (Java)

How to count spaces in a string (Java):

 The following code shows you how to count number of spaces in a string.

Code

String str1 = "i proud to be a pakistani";

             

int spaceCount = 0;

             

   for (int i = 0 ; i < str1.length() ; i++) {

                                                  

Here, checking each character of string whether it is space.. and if it is space then counter plus by one:

   

           if (Character.isWhitespace(str1.charAt(i))) {

                          

                  spaceCount++;

           }

   }

System.out.println("Total Number Of Spaces In Str1 is : " + spaceCount);

Output of the program is:

  Total Number Of Spaces In Str1 is : 5

ANOTHER WAY THROUGH SPACE ASCII VALUE:

String str1 = "proud to be a pakistani";

             

int spaceCount = 0;

             

   for (int i = 0 ; i < str1.length() ; i++) {

Here, checking each character of string with the space ASCII value that is 32 and if it is equal then counter plus by one:

 

         if (str1.charAt(i) == 32) {

                          

              spaceCount++;

                    

         }

   }

                    

System.out.println("Total Number Of Spaces In Str1 is : " + spaceCount);

Output of the program is:

  Total Number Of Spaces In Str1 is : 4
