import java.util.Scanner;

public class Main {

public static int vowels(String s) {

int count = 0;
s = s.toLowerCase();

for(char c: s.toCharArray()) {
if("aeiou".contains(c + "")) {
count++;
}
}

return count;

}

public static void main(String[] args) {

Scanner scnr = new Scanner(System.in);

String s = scnr.nextLine();

System.out.println("number of vowels: " + vowels(s));

scnr.close();

}

(Tokenizing Telephone Numbers) Write a program that inputs a telephone number as a string in the form (555) 555-5555. The program should use function strtok to extract the area code as a token, the first three digits of the telephone number as a token and the last four digits of the phone number as a token. The seven digits of the phone number should be concatenated into one string. The program should convert the area-code string to int and convert...

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. Ex: If the input is: 6 the output is: 011 6 in binary is...
##### Write a static method called "evaluate" that takes a string as a parameter
In Java language  Write a static method called "evaluate" that takes a string as a parameter. The string will contain a postfix expression, consisting only of integer operands and the arithmetic operators +, -, *, and / (representing addition, subtraction, multiplication, and division respectively). All operations should be performed as integer operations. You may assume that the input string contains a properly-formed postfix expression. The method should return the integer that the expression evaluates to. The method MUST use a stack...
