Write a java program to input a string and find the total number of uppercase letters in the string?
The code is given at the bottom. This code requires JAVA 1.5+ version to be compiled.This is very simple program. We ask user to input string and later we just iterate through all the character in the string. We use Character.isUpperCase() static method to check is the character we are checking is upper case if so we increase count variable by one. After iteration is done we print count variable and application quits.Note: for statement was introduced in 1.5 JAVA version.Example of usage:david-mac:~ david$ java TestEnter string: This is A Test String.Your string has 4 upper case letters.-------------------------import java.io.*;import java.lang.*;public class Test{public static void main(String[] args)throws IOException{BufferedReader in = new BufferedReader(new InputStreamReader(System.in));System.out.print("Enter string: ");String userString = in.readLine();int count = 0;for (char ch : userString.toCharArray()){if (Character.isUpperCase(ch)){count++;}}System.out.println("Your string has " + count + " upper case letters.");}}

Is space a token in java?
By default, no. The StreamTokenizer class ignores spaces as white space.If you need to make it a token, which you didn't specify, you can modify the default behavior by calling the function ordinaryChar (int ch), where ch is the character you would want to be treated as a token.From the Java SE 6 API documentation:ordinaryCharpublic void ordinaryChar(int ch) Specifies that the character argument is "ordinary" in this tokenizer. It removes any special significance the character has as a comment character, word component, string delimiter, white space, or number character. When such a character is encountered by the parser, the parser treats it as a single-character token and sets ttype field to the character value. Making a line terminator character "ordinary" may interfere with the ability of a StreamTokenizer to count lines. The lineno method may no longer reflect the presence of such terminator characters in its line count.Parameters:ch - the character.
