I am trying to make a 3x3 dimension(area of movements) using 2Dimensional array. My only problem is that as I run the program and chose left direction, the 3x3 dimension doesnt appear. It only shows 0. I wanna see the 3x3 dimension. What's the problem with my code?
Scanner input = new Scanner(System.in);
int[][]arr = {{0,0,0},{0,0,0},{0,0,0}};
int turtle =1;
for(int i=0;i<3;i++){
for(int j=0;j<3;j++){
System.out.println ("(1)Left(2)Right(3)Up(4)Down");
int movement = input.nextInt();
if(movement == 1){
if(turtle==1){
turtle = 1;
System.out.println ("Cant move left");
}
if(turtle ==2){
arr[0][0] = 1;
turtle = 3;
}
if(turtle ==3){
arr[0][2] = 1;
turtle = 2;
}
if(turtle ==4){
System.out.println ("Cant move left");
turtle = 4;
}
if(turtle ==5){
arr[1][0] = 1;
turtle = 4;
}
if(turtle ==6){
arr[1][1] = 1;
turtle = 5;
}
if(turtle ==7){
System.out.println ("cant move left");
turtle = 7;
}
if(turtle ==8){
arr[2][0] = 1;
turtle = 7;
}
if(turtle ==9){
arr[2][1] = 1;
turtle = 8;
}
}
System.out.printf ("%d",arr[i][j]);
}
System.out.println ();
}

Try this.
import java.util.Arrays;
for (int[] a : arr) {
System.out.println(Arrays.toString(a);
}
The other way would be to do the following.
for(int [] a : arr) {
for (int i = 0; i < a.length; i++) {
System.out.print(a[i] + " " );
}
System.out.println();
}
