JAVA MACHINE PROBLEM

Compile the code below. This program display the string value into uppercase letters.

import java.lang.*;
public class ToUpperCase {

public static void main(String[] args) {
String str = "hello it212 students";
char ch;
for ( int i = 0; i < str.length(); i++ ) {
ch = str.charAt(i);
System.out.print(Character.toUpperCase(ch));
}
}
}


Machine problem:
To "capitalize" a string means to change the first letter of each word in the string to upper case (if it is not already upper case). For example, a capitalized version of "Now is the time to act!" is "Now Is The Time To Act!". Write a subroutine named printCapitalized that will print a capitalized version of a string to standard output. The string to be printed should be a parameter to the subroutine. Test your subroutine with a main() routine that gets a line of input from the user and applies the subroutine to it.

Note that a letter is the first letter of a word if it is not immediately preceded in the string by another letter. Recall that there is a standard boolean-valued function Character.isLetter(char) that can be used to test whether its parameter is a letter. There is another standard char-valued function, Character.toUpperCase(char), that returns a capitalized version of the single character passed to it as a parameter. That is, if the parameter is a letter, it returns the upper-case version. If the parameter is not a letter, it just returns a copy of the parameter.

Sample
Input:
Take calculated risks. That is quite different from being rash.

Output:
Take Calculated Risks. That Is Quite Different From Being Rash.
