Write a Java program to capitalize each word in the string?

You can capitalize words in a string using the toUpperCase() method of the String class. This method converts the contents of the current string to Upper case letters.

Example

 Live Demo

public class StringToUpperCaseEmp {
   public static void main(String[] args) {
      String str = "string abc touppercase ";
      String strUpper = str.toUpperCase();
      System.out.println("Original String: " + str);
      System.out.println("String changed to upper case: " + strUpper);
   }
}

Output

Original String: string abc touppercase
String changed to upper case: STRING ABC TOUPPERCASE
