My first Java Code [PROBLEMS]

[JoshuaBritton]

hey, I don`t know a lot about codes, but at uni we have to do battleships Java code.
I have created this code so far but they are a lot errors, that I cant find out how to fix, I wound appreciate is some could give me a hand and tell were i going wrong. incomparable types: char and java.lang.String is the main error I font understand.

the code is ...

/**
 * @(#)Battleships.java
 *
 * Battleships application
 *
 * @author
 * @version 1.00 2012/3/11
 */

import java.util.Scanner;
public class bs3 {

    public static void main(String[] args) {

    //*instructions
    {
    System.out.println ("to play enter a number from 1-10 to place your ships, and the same to fire.");
    }

//*player grid
     int c[][]={
    	{1,2,3,4,5,6,7,8,9,10},
    	{1,0,0,0,0,0,0,0,0,0},
    	{2,0,0,0,0,0,0,0,0,0},
    	{3,0,0,0,0,0,0,0,0,0},
    	{4,0,0,0,0,0,0,0,0,0}};
    	for(int a=0;a<5;a++)
    	{

    //*keybord inputs
    Scanner fromkeyboard=new Scanner (System.in) ;
    int mynumberx=fromkeyboard.nextInt ();
    int mynumbery=fromkeyboard.nextInt ();

    //*ship inputs
    {
    int a=0,b=0;
    char[][] c=new char[10][4];
    if(c[a][b]=="1"||c[a][b+1]=="1");}

    //*3box ship
    {
    	c[a][b]="1";
    	c[a][b+1]="1";
    	c[a][b+2]="1";
    }

//*output (hit or miss)
    	System.out.print("");
    	for (int b=0;b<9;b++)

    	{System.out.print(c[a][b]);}
    	{	if(c[mynumberx][mynumbery]==1)
    			System.out.print("HIT");
    			else
    			System.out.print("MISS");
    	}
    }
}
}

thanks to anyone who may read this, I feel so silly having to do this but we got to start some place.

Character literals need single quotes, as in 'a', 'b' or 'c'; not double quotes (those are Strings) as in "a", "b" or "c".

The c array contains int values, the code is comparing its elements to Strings. The int 1 != to the String: "1"

... and below that int array c it is redefined as a char array. The OP should really read the compiler's error messages.

whoops

The second c is in {}s and hides the first one.

Lots going on here. Good "bad coding techniques" example.

Yup, and the indentation is worth zilch and makes me dizzy ;-)

p.s any good books to help, I am reading Head start and java for dummy`s ?
sorry about been pest.

Make sure the {}s are properly paired.

You have extra pairs of {} that are not needed.
