Hello, this is my code for a battleship game:

Is there anyway I can modify this and make it simpler/imporve it? I want to stream line it because I feel like it does some unnnecesary things that could be done better.

public class BattleshipLab

{

Scanner input = new Scanner(System.in);

public static final boolean DEBUG = false;

public static void breakln()

{

System.out.println("_____________________________________");

System.out.println("");

}

public static void createBoard(String[][] board)

{

for(int r = 0; r < board.length; r++)

{

for(int c = 0; c < board[0].length; c++)

{

board[r][c] = "~";

}

}

}

public static void showBoard(String[][] board)

{

breakln();

for(int r = 0; r < board.length; r++)

{

if(DEBUG == true)

{

for(int c = 0; c < board[0].length; c++)

{

System.out.print(" "+board[r][c]);

}

System.out.println("");

}

else

{

for(int c = 0; c < board[0].length; c++)

{

if(board[r][c].equals("S"))

{

System.out.print(" "+"~");

}

else

{

System.out.print(" "+board[r][c]);

}

}

System.out.println("");

}

}

breakln();

}

public static void createShip(String[][] board,int size)

{

if(Math.random() < 0.5)

{

int col = (int)(Math.random()*5);

int row = (int)(Math.random()*7);

for(int i = 0; i

{

board[row][col+i] = "S";

}

}

else

{

int col = (int)(Math.random()*7);

int row = (int)(Math.random()*5);

for(int i = 0; i

{

board[row+i][col] = "S";

}

}

}

public static int userFire(String[][] board, int hits, int torps)

{

Scanner input = new Scanner(System.in);

int row,col;

System.out.println("You have: "+ torps +" torpedos left!");

System.out.println("Select a row to fire in: ");

row = input.nextInt();

while(row > 8 || row < 1) // Error checking for row

{

System.out.println("Enter a valid row (1 -> 8)");

row = input.nextInt();

}

System.out.println("Select a column to fire in: ");

col = input.nextInt();

while(col > 8 || col < 1) // Error checking for column

{

System.out.println("Enter a valid col (1 -> 8)");

col = input.nextInt();

}

if(board[row-1][col-1].equals("S"))

{

hits ++;

System.out.println("~~~~~~~ HIT ~~~~~~~");

board[row-1][col-1] = "!";

}

else

{

System.out.println("~~~~~~~ MISS ~~~~~~~");

board[row-1][col-1] = "M";

}

return hits;

}

public static void finall(int hits, int torps)

{

if(hits < 4)

System.out.println("Sorry, but you lost because you didn't sink the ship.");

if(torps < 1)

System.out.println("You have lost all your torpedos");

else

if(hits >= 4)

{

System.out.println("You have beaten the game battleship, Thanks for playing!");

}

System.out.println("Good game, well played!");

}

public static void main(String[] arg)

{

String[][] board = new String[8][8];

createBoard(board);

createShip(board, 4);

int torps = 15;

int hits = 0;

/// Starting real stuff

while(torps > 0 && hits < 4)

{

showBoard(board);

hits = userFire(board, hits, torps);

torps --;

}

finall(hits, torps);

}

}
