Hello I am in my first year of java and currently I am in chapter 2 at my high school. I am stuck on some of the question programs and though if anyoen here can help me.

NOTE:I am using Netbeans

Here are some question programs:

1. Design and implement an application that reads a string from the user, then determines and prints how many of each lowercase vowel (a,e,i,o,u) appear in the string. Have a seperate counter for each vowel. Also count and print the number of constants,spaces, and punctuation marks.

2. Design and implement an application that simulates a simple slot machine in which three numbers between 0 and 9 are randomly selected and printed side by side. Print a statement saying all three of the numbers are the same, or any two of the numbers are the same, when this happens. Keep playing until the user chooses to stop.

3. Desing and implement an applet that draws the side view of stair steps from the lower left to the upper right,

Thanls Alot

You should try a little bit. What is the code you have written so far? Did you try searching building blocks of you code like "reading string from user"? If we see your code, we can try helping. We can not write your homework for you. It is not good for you.

Code:

    public static void main(String[] args) {
        make a Scanner for/with System.in
        boolean your_boolean
        while(your_boolean) {
            ask user to enter text
            get user input with scanner.nextLine()
            process the line of input for your requirements
            ask user if they want more
            get user input with nextLine
            your_boolean = evaluate input
