Get and set not working as expected reading array from different class

I have a ship locations class which i wish to use to store the locations of each players ships, i set this sub in my client class. I then wish to read it back from a different class called game session. Im creating a new ShipLocatiopns(); object however i was under the impression that by making the array static i will be able to read it from other classes regardless
This is the code in my game session which then reads the getsub method from ship locations,when i read this out i will always get {{0,0},{0,0}} even after I have set this in battle ship
Is it actually possible to set a array from one class, then read it back in another.I believe the problem relies in the game session class(the while loop below) as this is the only place where it doesnt seem to get the correct array

while(drawBoard){
		    	  System.out.println("While statment reached");
		    	  
		    	 
		    	 
		 		 int row = fromPlayer1.readInt();
		    	 int column = fromPlayer1.readInt();
		    	 System.out.println("the row and col "+row + column);
		    	 char shipT=fromPlayer1.readChar();
		    	 System.out.println("the char charcter set "+shipT);//null
		    	 Thread.sleep(5000);
		    	 ShipLocations sl = new ShipLocations();
		    	 if(sl.p1sub==null)
		    	 {
		    		 System.out.println("array is null");
		    	 }
		    	 System.out.println(Arrays.deepToString(sl.getp1sub()));
}

}

this is my shipLocations class

public class ShipLocations {

	
	static int [][] p1sub;
	
	public ShipLocations()
	{
		p1sub = new int[2][2];
		
	}
	public int[][] getp1sub()
	{
		return p1sub;
	}
	public void setp1sub(int[][] local) {
		for (int i = 0;i <local.length;i++)
		{
			for(int j = 0;j<local.length;j++)
			{
				p1sub [i][j]= local[i][j];
				System.out.println("set method"+p1sub[i][j]);
			}
		}
		
	}
