A little bit of help please...

Question

I've been working on a project for school and I had it working pretty good, but then I did something and now it won't run. It compiles with no errors, but when I go to run it...it just doesn't do anything. Any help would be great :]
import java.util.Scanner;
import java.util.Stack;
public class StackTest
     Scanner scanner = new Scanner(System.in);
    Stack<Character> stack = new Stack<Character>();
    Stack<Character> stack2 = new Stack<Character>();
    Stack<Character> junkStack = new Stack<Character>();
    String inputLine = "";
    String searchString = "";
    int junk;
    public void reverse(String inputLine)
          // push all characters on the stack
        for(int i = 0; i < inputLine.length(); i++)
                char temp = inputLine.charAt(i);
                stack.push(new Character(temp));
        //Reverse the string onto another stack           
        while(stack.empty() != true)
                 stack2.push(stack.pop());
    public void searchForString(char firstSearchLetter, char lastSearchLetter)
            for(int i = 0; i < stack2.size(); i++)
                if(stack2.peek() == firstSearchLetter)
                      junkStack.push(stack2.pop());
                      while(stack2.peek() != lastSearchLetter)
                           junkStack.push(stack2.pop());
                       junkStack.push(stack2.pop());
                 else
                      stack.push(stack2.pop());
     public int calculateJunk(Stack junkStack)
          int junk = junkStack.size() - searchString.length();
          return junk;
     public void main(String[] args)
          System.out.print("Please enter your sentence: ");
        inputLine = scanner.nextLine();
        StackTest st = new StackTest();
        st.reverse(inputLine);
        System.out.println("Stack2: " + stack2);
        System.out.println("Stack: " + stack);
        System.out.println("Please enter the search string: ");
        searchString = scanner.nextLine();
        char firstSearchLetter = searchString.charAt(0);
        char lastSearchLetter = searchString.charAt(searchString.length() - 1);
        System.out.println("first letter: " + firstSearchLetter);
        System.out.println("last letter: " + lastSearchLetter);
        System.out.println("junkStack: " + junkStack);
        System.out.println("stack: " + stack);
        System.out.println("junk in between: " + junk);
}

I haven't stared at your code, but why not move the logic in your main into a method, for starters?
public void run() {
          System.out.print("Please enter your sentence: ");
        inputLine = scanner.nextLine();
        st.reverse(inputLine);
        System.out.println("Stack2: " + stack2);
        System.out.println("Stack: " + stack);
        System.out.println("Please enter the search string: ");
        searchString = scanner.nextLine();
        char firstSearchLetter = searchString.charAt(0);
        char lastSearchLetter = searchString.charAt(searchString.length() - 1);
        System.out.println("first letter: " + firstSearchLetter);
        System.out.println("last letter: " + lastSearchLetter);
        System.out.println("junkStack: " + junkStack);
        System.out.println("stack: " + stack);
        System.out.println("junk in between: " + junk);
public static void main(String[] args) {
    StackTest st = new StackTest();
    st.run();
