well im new to java. and wanted to try the problem i encountered in C++
the Knight's tour

here's my problem, i want to put the result of the tour in a frame

Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class trialagainKT extends Frame {
  public static void main(String[] args){
  int x;
  int y;
  String Number1;
  String Number2;
  
  Number1 =JOptionPane.showInputDialog("enter x: ");
  Number2 =JOptionPane.showInputDialog("enter Y: ");
   		
   		x = Integer.parseInt(Number1);
   		y = Integer.parseInt(Number2);
   		
   	  	PerformKT(x, y); 	   	
  }
   	
public static void PerformKT(int currentRow, int currentColumn) {
		if (currentRow > 7 || currentRow < 0 || currentColumn  >  7 || currentColumn < 0) {
			JOptionPane.showMessageDialog(null,"Invalid Start Square ","Try Again",JOptionPane.PLAIN_MESSAGE);
		}
		//initialization of board
		int chessBoard[][] = new int[8][8];
		int horizontal[] = { 2, 1, -1, -2, -2, -1, 1, 2 };
		int vertical[] = { -1, -2, -2, -1, 1, 2, 2, 1 };
		int counter = 1;
		boolean legalMove[] = new boolean[8];
		int moveNumber = 0;
		int accessibility[][] = 
			{{2,3,4,4,4,4,3,2},{3,4,6,6,6,6,3,4},{4,6,8,8,8,8,6,4},{4,6,8,8,8,8,6,4},
			 {4,6,8,8,8,8,6,4},{4,6,8,8,8,8,6,4},{3,4,6,6,6,6,3,4},{2,3,4,4,4,4,3,2}};
		
		
		chessBoard[currentRow][currentColumn] = counter;
		
		for(counter = 2; counter <= 64; counter++) {
			for(int i = 0; i < 8; i++) {
				legalMove[i] = false; //reset leaglMove array to false
			}
			moveNumber = 0; //reset moveNumber to 0
			
			//check the possible moves for the knight
			while (moveNumber < 8) {
				int checkR = currentRow + vertical[moveNumber];                         
     			int checkC = currentColumn + horizontal[moveNumber];
				
				if (checkR >= 0 && checkR <= 7 && checkC >= 0 && checkC <= 7) {
					//check if legal move is occupied
					if (chessBoard[checkR][checkC] == 0) {
						accessibility[checkR][checkC]--;
						legalMove[moveNumber] = true;
					} else {
						legalMove[moveNumber] = false;
					}
				} else {
					legalMove[moveNumber] = false;
				}
				++moveNumber;
			}

			//what is the best move?
			int bestAccess = 8;
			int bestMove = -1;
			
			for(int i = 0; i < 8; i++) {
				if(legalMove[i] == true) {
					int checkR = currentRow + vertical[i];
   	   				int checkC = currentColumn + horizontal[i];

     	 			if (accessibility[checkR][checkC] <= bestAccess) {
     	    			bestAccess = accessibility[checkR][checkC];
     	    			bestMove = i;							//Store first legal move with lowest accessibility
     	 			}
				}
			}
			
			//move the knight
			currentRow += vertical[bestMove];
			currentColumn += horizontal[bestMove];
			
			chessBoard[currentRow][currentColumn] = counter;
		}
		//this is what i want to put in the frame
                System.out.println();
		System.out.println("  00  01  02  03  04  05  06  07 ");
		System.out.println("*---*---*---*---*---*---*---*---*");
		for(int i=0; i < chessBoard.length; i++) {
			for(int j=0; j < chessBoard[i].length; j++) {
				System.out.printf("|%3d", chessBoard[i][j]);
			}
			System.out.println("|");
			System.out.println("|   |   |   |   |   |   |   |   |");
			System.out.println("*---*---*---*---*---*---*---*---*");
			}
		
//this is for the frame
	JTextArea outputArea = new JTextArea (15,30);
    	outputArea.setFont(new Font("Courier",Font.BOLD,16));
    	JScrollPane scroller = new JScrollPane(outputArea);
//no particular output yet

    	String title="Complete Knight's Tour";
