    Question language Recognizer

    Hi

    this is my project question in Data Structures



    and this is the code

    PHP Code:
    import java.util.Scanner;

    class 
    Stack {

        private 
    int top = -1;
        private 
    char stack[] = new char[10];

        public 
    void push(char a) {
            
    stack[++top] = a;
        }

        public 
    char pop() {
            return (
    charstack[top--];
        }

        public 
    void refill() {
            
    top stack.length 1;
        }

        public 
    void reset() {
            
    top = -1;
        }
    }

    public class 
    Class1 {

        public static 
    void main(String[] argsthrows Exception {
            
    Stack s1 = new Stack();
            
    Stack s2 = new Stack();
            
    Stack s3 = new Stack();

            
    boolean isPartOf false;

            
    Scanner input = new Scanner(System.in);
            
    int n0;
            
    char chch1ch2;

            
    System.out.println("========================================================================= ");
            
    System.out.println("Enter 10 letters for the language , , , WITHOUT SPACES BETWEEN THE LETTERS");

            for (
    int i 010i++) {
                
    ch = (charSystem.in.read();
                
    s1.push(ch);
            }

            
    System.out.println("========================================================================= ");
            
    System.out.println("The valid characters of your language are:");

            for (
    int i 010i++) {
                
    System.out.print(1);
                
    System.out.println(") ");
            }

            
    System.out.println("========================================================================= ");
            
    System.out.println("Enter the number of the letters of the word you want to check");

            
    input.nextInt();

            
    System.out.println("========================================================================= ");
            
    System.out.println("Enter the word you need to check");

            for (
    int i 0ni++) {
                
    ch = (charSystem.in.read();
                
                
    s2.push(ch);
                
            }
            for (
    int i 0ni++) {
                
    ch1 s2.pop();
                
    s1.refill();
                 
                for (
    int j 010j++) {
                    
    ch2 s1.pop();
                                if (
    ch1 == ch2) {
                        
    isPartOf true;
                        
    r++;
                        
    s3.push(ch2);
                        
    System.out.println("ch2 = " ch2);
                    } else if (
    isPartOf) {
                        
    isPartOf false;
                        break;
                    }
                }
            }
            if (
    isPartOf) {
                
    System.out.println("========================================================================= ");
                
    System.out.println("The word is part of the language\n");
            } else {
                
    System.out.println("========================================================================= ");
                
    System.out.println("The word is not a part of the langauge\n");
            }
        }

    Add some comments to the program's output saying what is wrong with it and show what it should be.

    Please copy and paste here the contents of the command prompt window. Images do not allow copy or find of their contents.

    To copy the contents of the command prompt window:
    Click on Icon in upper left corner
    Select Edit
    Select 'Select All' - The selection will show
    Click in upper left again
    Select Edit and click 'Copy'

    Paste here.
    If you don't understand my answer, don't ignore it, ask a question.
