how to capitalize the first letter of a string in java

Question

I have a presentation about capitalize the first letter of each word of a sentence 
I write a program like that :

 public static void main(String[] args){
	 Scanner in = new Scanner(System.in);
         System.out.print("Input a Sentence: ");
	 String line = in.nextLine();
	 String upper_case_line = ""; 
         Scanner lineScan = new Scanner(line); 
         while(lineScan.hasNext()) {
             String word = lineScan.next(); 
             upper_case_line += Character.toUpperCase; 
         }
      System.out.println(upper_case_line); 
    }

But it gives some error:

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol
  symbol:   variable toUpperCase
  location: class java.lang.Character
	at javastackoverflow.NewClass1.main(NewClass1.java:15)

What is the error ?

Answer 1

You can use trim method to take a upper case number after space:

 public static void main(String[] args){
	 Scanner in = new Scanner(System.in);
         System.out.print("Input a Sentence: ");
	 String line = in.nextLine();
	 String upper_case_line = ""; 
         Scanner lineScan = new Scanner(line); 
         while(lineScan.hasNext()) {
             String word = lineScan.next(); 
             upper_case_line += Character.toUpperCase(word.charAt(0)) + word.substring(1) + " "; 
         }
      System.out.println(upper_case_line.trim()); 
    }

Happy coding
