Hi Fellow EE'rs

Could someone please assist me with creating code to handle a stack? What would be the required driver programs needed for this?

Many Thanks

Not at my own pc but does the following look ok to setup a stack and add from keyboard input?

public class CChar {

      private char CharVal;


      public CChar() {
            Stack stack = new Stack();
            CharVal = ' ';
      }


      public void setCharValFromKeyboard() {
            try {
                  BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
                  System.out.print("Character to add to stack: ");
                  CharVal = (char) in.read();
                        stack.push(CharVal);
                  System.out.println();

            }
            catch (Exception e) {
            }

      }
   
}

close , try more like this:

public class CChar {

       BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
      Stack stack = new Stack();

      public CChar() {
      }


      public void setCharValFromKeyboard() {
            try {
                  System.out.print("Character to add to stack: ");
                  char charVal = (char) in.read();
                  stack.push(charVal);
                  System.out.println();

            }
            catch (Exception e) {
            }

      }
   
}

Thanks for that

Would it just be a case of the following to remove stack values and to print a stack contents?

public void popStackValue() {
       try {
             System.out.println("The poped value is " + stack.pop());
             System.out.println("The new stack size is" + stack.size());
             }
}

public void printStack() {
      try {
            System.out.println("The contents of  the Stack are" + stack);
            }
}

Would that be the correct way to print out the stack contents?

Many Thanks
Steve
