java - Array overwriting all other values when a new one is added -

i have been having issue when adding objects array. seems every single time add new woodfloor object array, overwrites of other values of array. here's code:

package code;  public class main {  private static block[] blocks = new block[12];  public static void main(string[] args) {     for(int = 0; < 12; i++) {         blocks[i] = new woodfloor(i * 10, * 20);     }   } }    package code;  public class block {  protected static int x, y;  public block(int x, int y) {     this.x = x;     this.y = y; }  public int getx() {     return x; }  public int gety() {     return y; }  }   package code;  public final class woodfloor extends block {  public woodfloor(int x, int y) {     super(x, y); }  } 

don't use static modifier class fields need different each instance. static modifier makes field class field, 1 shared instances, , not want.

so change this:

protected static int x, y; 

to this:

protected int x, y;
