How to print the first character of each word in a String in Java?

A String class can be used to represent the character strings, all the string literals in a Java program are implemented as an instance of a String class. The Strings are constants and their values cannot be changed (immutable) once created.

We can print the first character of each word in a string by using the below program.

Example

public class FirstCharacterPrintTest {
   public static void main(String[] args) {
      String str = "Welcome To Tutorials Point";
      char c[] = str.toCharArray();
      System.out.println("The first character of each word: ");
      for (int i=0; i < c.length; i++) {
         // Logic to implement first character of each word in a string
         if(c[i] != ' ' && (i == 0 || c[i-1] == ' ')) {
            System.out.println(c[i]);
         }
      }
   }
}

Output

The first character of each word: 
W
T
T
P
