Given string str, the task is to print the last character of each word in the string.

Examples:  

Input: str = “Geeks for Geeks” 
Output: s r s

Input: str = “computer applications” 
Output: r s 

Approach: Append an area i.e. ” “ at the top of the given string in order that the last word within the string is additionally followed by an area a bit like all the opposite words within the string. Now start traversing the string character by character, and print every character which is followed by an area .
Below is that the implementation of the above approach:

// Java implementation of the approach
class GFG {

	// Function to print the last character
	// of each word in the given string
	static void printLastChar(String str)
	{

		// Now, last word is also followed by a space
		str = str + " ";
		for (int i = 1; i < str.length(); i++) {

			// If current character is a space
			if (str.charAt(i) == ' ')

				// Then previous character must be
				// the last character of some word
				System.out.print(str.charAt(i - 1) + " ");
		}
	}

	// Driver code
	public static void main(String s[])
	{
		String str = "Geeks for Geeks";
		printLastChar(str);
	}
}

Output: 

s r s
