java pacman - ループは配列を通して1回だけ反復する

Question

プログラムの出力に問題があります。私はグリッドを生成し、パクマンの向きを変えて移動させることができますが、それは最初の位置から移動した後、方向付けまたは移動を停止します。何かが間違っている必要がありますプログラムが繰り返す方法で、私は何がわからない。

package javaapplication2; 
import java.util.*; 

public class JavaApplication2 { 
    int index; 
    int index2; 
    final int ARRAY_SIZE = 10; 
    final int ARRAY_SIZE2 = 10; 
    String [][] myArray = new String [ARRAY_SIZE][ARRAY_SIZE2]; 
    String output; 

public static void main(String[] args) 
{ 

    JavaApplication2 pacman = new JavaApplication2(); 
    pacman.createPacman(); 
    pacman.generateArray(); 
    Scanner input = new Scanner(System.in); 
    int m = input.nextInt(); 
    pacman.orientPacman(m); 



} 
public void generateArray(){ 


    for (index = 0; index < ARRAY_SIZE; index++) 
    { 
     for (index2 = 0; index2 < ARRAY_SIZE2; index2++) 
     { 
      Random rand = new Random(); 
      int value = rand.nextInt(50); 
      if (myArray[index][index2] == "<") 
       myArray[index][index2] = "<"; 
      else if (myArray[index][index2] == " ")

最初の繰り返しで実行されているかどうかを確認します。

また、2番目のインデックスと3番目のインデックス値が空であるかどうかを確認してください。
